Best 6 Lug To 5 Lug Conversion Kit for Wheel Changes

Best 6 Lug To 5 Lug Conversion Kit

A strong 6-to-5-lug conversion choice matches your vehicle’s 6-lug pattern to the exact 5-lug pattern on your aftermarket wheels, making these kits a fit-focused option for owners changing wheel styles. This roundup compares ten products, including 6×5.5 adapters converting to 5×4.5, 5×5, 5×5.5, or 5×4.75, plus one 6×135 option. The products differ in adapter count, thickness, hub bore, and listed vehicle applications, so a matching bolt pattern alone is not enough to confirm fit.

Check the vehicle-side pattern, wheel-side pattern, center bore, stud thread, and vehicle application before ordering. We rank direct wheel-adapter kits ahead of a rear axle conversion kit, which serves a different installation purpose.

The ECCPP 4PCS 6×5.5 to 5×4.5 adapters lead as the Best Overall pick because they provide four 2-inch adapters and list broad fitment across vehicles including Silverado 1500, Tahoe, Sierra 1500, and Yukon. They are for 6×5.5 vehicles using aftermarket 5×4.5 wheels, not original wheels or tires. Confirm your exact vehicle fit and wheel specifications before buying; this pattern is not interchangeable with 5×5 or 5×5.5.

Detailed Reviews: Best 6 Lug To 5 Lug Conversion Kit

ECCPP 6x5.5 to 5x4.5 Adapters

#1 · Best Overall

1. ECCPP 6×5.5 to 5×4.5 Adapters

  • Weight: 24.4 lb
  • Dimensions: 11.6 x 7.27 x 6.87 in

Best for: 5×4.5 wheels for listed GM vehicles.

Why it ranks #1: Four 2-inch adapters convert 6×5.5 to 5×4.5, with listed fitment across Silverado 1500, Tahoe, Sierra 1500, and other vehicles.

ECCPP’s four-piece kit converts a 6×5.5 vehicle pattern to 5×4.5, enabling compatible aftermarket wheels on a wide range of listed Chevrolet and Cadillac applications. Its application list includes Tahoe, Silverado 1500, Escalade, and Express models, while the supplied facts explicitly rule out OEM tires.

The change from 6×5.5 to 5×4.5 is useful when the vehicle and intended aftermarket wheel match those patterns. ECCPP’s fitment list covers several Chevrolet and Cadillac vehicles, including Tahoe, Silverado 1500, Escalade, and Express applications, offering a starting point for year-specific checks. The product description says OEM tires are not for this setup and calls for aftermarket 5×4.5 wheels. Buyers therefore need to plan for the wheel change alongside the adapter installation.

Pros
  • Converts 6×5.5 vehicle pattern to 5×4.5
  • Four adapters included
  • Fitment list covers Chevrolet and Cadillac models
  • Aftermarket wheel pattern is explicitly specified
Cons
  • OEM tires are not for this setup; aftermarket 5×4.5 wheels are required.

Skip it if you need 5×5 wheels; ECCPP’s B0D54BNB9J kit changes 6×5.5 to that wheel pattern.

A listed Chevrolet or Cadillac owner seeking to use aftermarket 5×4.5 wheels is the right buyer. Check the vehicle application and plan around the stated incompatibility with OEM tires.

YIZBAP 6x5.5 to 5x4.5 Adapters

#2 · Best Spec Detail

2. YIZBAP 6×5.5 to 5×4.5 Adapters

Best for: Silverado 5×4.5 wheel conversion.

Why it ranks #2: Its 2-inch thickness, 108mm hub bore, and 14×1.5 studs are specified, alongside 6×5.5-to-5×4.5 fitment for Silverado 1500 and Tahoe.

YIZBAP specifies a 6×5.5-to-5×4.5 conversion with a 108mm hub bore, enabling compatible 5×4.5 wheels on listed 6×5.5 vehicles. The two-inch thickness and 14×1.5 studs supply important setup dimensions, while the application list includes Silverado 1500, Tahoe, Suburban, and Avalanche models.

The adapter’s two-inch thickness and change from 6×5.5 vehicle pattern to 5×4.5 wheel pattern define both the conversion and its spacing. A 108mm hub bore and 14×1.5 studs offer concrete dimensions for evaluating a proposed setup. YIZBAP explicitly limits wheel compatibility to 5×4.5, excluding 6×5.5 wheels, so the wheel’s pattern must match the adapter. Listed vehicle applications provide a starting point for checking the relevant model and year.

Pros
  • Converts 6×5.5 vehicle pattern to 5×4.5 wheel pattern
  • 108mm hub bore specified
  • Two-inch thickness specified
  • 14×1.5 threaded studs
Cons
  • It does not fit 6×5.5 wheels; the wheel pattern must be 5×4.5.

Skip it if you need 5×5.5 wheels; ECCPP’s B0FNMHGMBB adapter set changes 6×5.5 to that pattern.

For owners of listed Silverado, Tahoe, Suburban, or Avalanche applications seeking compatible 5×4.5 wheels, this provides defined conversion dimensions. The wheel pattern remains the critical fit boundary.

#3 · Best 5×5 Fit

3. ECCPP 6×5.5 to 5×5 Adapters

  • Weight: 25.9 lb
  • Dimensions: 12.99 x 8.46 x 7.87 in

Best for: 5×5 aftermarket wheel conversion.

Why it ranks #3: Four 2-inch adapters convert 6×5.5 to 5×5, serving buyers who have aftermarket wheels with that exact five-lug pattern.

ECCPP’s four-adapter kit changes a 6×5.5 vehicle pattern to 5×5, enabling compatible aftermarket wheels on listed Chevrolet and GMC applications. Its two-inch thickness is specified, and the product clearly excludes stock rims, making wheel selection a central part of this conversion.

The 6×5.5-to-5×5 pattern change allows use of aftermarket wheels with the matching five-lug pattern; ECCPP explicitly says stock rims do not fit this setup. A two-inch thickness defines the adapter’s spacing, while the fitment information names Silverado 1500 and several GMC applications. That combination helps buyers assess both the vehicle and replacement wheel before installation. The listing also advises matching bolt count, bolt-circle diameter, center bore, and bolt size to the intended application.

Pros
  • Changes 6×5.5 vehicle pattern to 5×5
  • Two-inch thickness specified
  • Four adapters included
  • Fitment details include Chevrolet and GMC applications
Cons
  • Stock rims are not compatible; aftermarket 5×5 wheels are required.

Skip it if you need 5×4.5 wheels; ECCPP’s B0FNMFPGC9 kit converts a 6×5.5 vehicle to that pattern.

This suits a listed Chevrolet or GMC owner who wants to mount aftermarket 5×5 wheels on a 6×5.5 vehicle. Stock rims are excluded, so wheel choice is the important boundary.

SCITOO 6x5.5 to 5x4.5 Adapters

#4 · Wide Vehicle List

4. SCITOO 6×5.5 to 5×4.5 Adapters

  • Weight: 24.4 lb
  • Dimensions: 4.13 x 15.75 x 12.6 in

Best for: Broad 5×4.5 vehicle coverage.

Why it ranks #4: This four-piece, 2-inch 6×5.5-to-5×4.5 set lists many Chevrolet applications and specifies a 108mm bore and 14×1.5 studs.

SCITOO’s four-piece set combines a 6×5.5-to-5×4.5 conversion with a 108mm bore and 14×1.5 studs, enabling compatible 5×4.5 wheels on listed vehicles. Its application list spans Chevrolet models including Tahoe, Silverado 1500, Express, and Suburban, giving buyers broad vehicle coverage to assess.

The 5×4.5 wheel pattern and 6×5.5 vehicle pattern define the conversion, while the 108mm bore and 14×1.5 studs give buyers additional dimensions for setup comparison. The listed applications cover several Chevrolet truck, SUV, and van models across specified years, which can help narrow whether the set applies to a particular vehicle. SCITOO identifies aluminum alloy as the material and describes hot-forged aircraft-grade aluminum, connecting the material choice with its stated strength-to-weight emphasis.

Pros
  • Converts 6×5.5 vehicle pattern to 5×4.5 wheel pattern
  • 108mm bore
  • 14×1.5 studs
  • Four-piece set
Cons
  • This set is for 5×4.5 wheels, not other five-lug patterns.

Skip it if you need 5×5 wheels; ECCPP’s B0D54BNB9J set converts a 6×5.5 vehicle to that pattern.

Consider this for a listed Chevrolet vehicle when the intended wheel is 5×4.5 and the bore and stud dimensions match. The broad application list still requires checking the specific vehicle year.

ECCPP 6x5.5 to 5x5.5 Adapters

#5

5. ECCPP 6×5.5 to 5×5.5 Adapters

  • Weight: 22.1 lb
  • Dimensions: 11.6 x 7.27 x 6.68 in

Best for: 5.5-inch aftermarket wheel conversion.

Why it ranks #5: Four 2-inch adapters convert a 6×5.5 vehicle pattern to 5×5.5, with listed fitment for Silverado 1500, Tahoe, Sierra 1500, and others.

A 6×5.5-to-5×5.5 bolt-pattern change is the defining feature of ECCPP’s four-adapter set, enabling a compatible 5×5.5 aftermarket wheel on a listed 6×5.5 vehicle. Its application list covers models including Chevrolet Tahoe, Silverado 1500, Suburban, and GMC Yukon, making vehicle-specific coverage central to choosing it.

The two-inch thickness gives the adapters a specified spacer depth as they change the vehicle pattern from 6×5.5 to 5×5.5. That conversion is useful only with a wheel using the new 5×5.5 pattern: the supplied facts explicitly say not to use the OEM tires and call for aftermarket wheels. The broad fitment list names multiple Chevrolet, GMC, and Ram applications, so buyers can check their model and year against that list before planning installation.

Pros
  • Changes 6×5.5 vehicle pattern to 5×5.5 wheel pattern
  • Four adapters included
  • Two-inch thickness specified
  • Fitment list includes Chevrolet, GMC, and Ram vehicles
Cons
  • Requires aftermarket 5×5.5 wheels; OEM tires are not for this setup.

Skip it if you need a 5×4.5 wheel pattern; ECCPP’s B0FNMFPGC9 kit converts to that pattern instead.

A Tahoe, Silverado, or other listed vehicle owner seeking to run aftermarket 5×5.5 wheels is the intended buyer. Check the year and application, and remember the conversion does not use OEM tires.

PHILTOP 6x5.5 to 5x5.5 Adapters

#6

6. PHILTOP 6×5.5 to 5×5.5 Adapters

  • Weight: 11.05 lb
  • Dimensions: 6 x 7.5 x 7.8 in

Best for: Tahoe 5×5.5 conversion setup.

Why it ranks #6: The 2-inch adapters specify 6×5.5 vehicle and 5×5.5 wheel patterns, 108mm hub bore, M14x1.5 thread, and a recommended torque range.

PHILTOP changes a 6×5.5 vehicle pattern to 5×5.5, with a 108mm hub bore and M14x1.5 thread pitch. That combination enables use of compatible 5×5.5 wheels while giving buyers key dimensions for setup checks; its two-inch thickness also defines the adapter’s spacing.

The 6×5.5-to-5×5.5 pattern change is the core function, and the two-inch thickness establishes the adapter’s specified offset from the hub. A 108mm hub bore and M14x1.5 thread pitch add useful fitment dimensions, while the listing gives a recommended torque of 85–90 ft/lbs. PHILTOP notes that vehicle bolts extending beyond the adapter thickness need cutting, an installation condition worth checking before assembly. The supplied vehicle-application text includes Chevrolet models.

Pros
  • Converts 6×5.5 vehicle pattern to 5×5.5 wheel pattern
  • 108mm hub bore
  • M14x1.5 thread pitch
  • Recommended torque of 85–90 ft/lbs specified
Cons
  • Vehicle bolts longer than the adapter thickness need cutting.

Skip it if you need 5×4.5 wheels; YIZBAP’s B09K72YR4Y adapter converts a 6×5.5 vehicle to that pattern.

A buyer with a listed 6×5.5 vehicle seeking 5×5.5 wheels can use the stated bore, thread, and torque details to assess the setup. Check bolt length because longer bolts require cutting.

FLYCLE 6x5.5 to 5x4.5 Adapters

#7

7. FLYCLE 6×5.5 to 5×4.5 Adapters

  • Weight: 11.64 lb

Best for: 5×4.5 wheel pattern conversion.

Why it ranks #7: These 2-inch adapters specify a 6×5.5-to-5×4.5 conversion, 108mm center bore, and 14×1.5 thread pitch, but emphasize a narrower wheel match.

FLYCLE’s 6×5.5-to-5×4.5 conversion pairs a 108mm center bore with 14×1.5 studs, enabling specified 5×4.5 wheels on a 6×5.5 vehicle. The key selection point is strict pattern matching: the listing says it works only with 5×4.5 wheels, not 6×5.5 wheels.

The two-inch thickness supplies a defined spacer depth while the adapter changes the vehicle’s 6×5.5 pattern to the wheel’s 5×4.5 pattern. Its 108mm center bore and 14×1.5 thread pitch give buyers additional dimensions to compare with their setup. FLYCLE also lists a recommended torque of 85–90 lb, which provides an installation reference in the supplied specifications. The stated wheel-pattern restriction makes checking the wheel pattern essential before purchase.

Pros
  • Converts 6×5.5 vehicle pattern to 5×4.5 wheel pattern
  • 108mm center bore specified
  • 14×1.5 thread pitch specified
  • Recommended torque of 85–90 lb provided
Cons
  • It accepts only 5×4.5 wheels, not 6×5.5 wheels.

Skip it if you need 5×5.5 wheels; ECCPP’s B0FNMHGMBB adapter set converts a 6×5.5 vehicle to that pattern.

Choose this for a 6×5.5 vehicle setup that needs 5×4.5 wheels and matches the listed bore and stud specifications. Its stated wheel-pattern restriction rules out using 6×5.5 wheels.

ECCPP 6x5.5 to 5x4.75 Adapters

#8

8. ECCPP 6×5.5 to 5×4.75 Adapters

  • Weight: 11.4 lb
  • Dimensions: 8.39 x 7.68 x 7.6 in

Best for: 5×4.75 wheel-pattern conversion.

Why it ranks #8: The 2-inch adapters offer a less common 5×4.75 wheel pattern and 78.1mm center bore, but the listing is for two pieces rather than four.

ECCPP’s two-piece set converts a 6×5.5 vehicle pattern to 5×4.75 and specifies a 78.1mm center bore with 14×1.5 studs. Those dimensions enable a targeted five-lug wheel conversion for listed applications, including Silverado 1500, Suburban, and Tahoe models.

The conversion to 5×4.75 is the defining fitment, while the 78.1mm center bore and 14×1.5 studs provide further dimensions to compare against a vehicle and wheel setup. The two-inch adapters change the pattern and add their specified thickness. ECCPP lists applications including Chevrolet and Cadillac models and says the product meets OE specifications in form, fit, and function. The listing also urges checking bolt count, circle diameter, center bore, and bolt size.

Pros
  • Changes 6×5.5 vehicle pattern to 5×4.75
  • 78.1mm center bore specified
  • 14×1.5 studs
  • Two-inch thickness
Cons
  • The target wheel pattern is 5×4.75, not 5×4.5 or 5×5.

Skip it if you need 5×4.5 wheels; SCITOO’s B0D5M5HFQ2 adapter set converts 6×5.5 to that pattern.

This is for a buyer whose 6×5.5 vehicle and intended wheel both match the stated 5×4.75 conversion and dimensions. Check the center bore and stud specifications as part of fitment.

ezaccessory 6x135 to 5x5 Adapters

#9

9. ezaccessory 6×135 to 5×5 Adapters

  • Weight: 24.2 lb

Best for: F-150 and Navigator wheel swap.

Why it ranks #9: Four adapters convert 6×135 vehicle hubs to 5×5 wheels, making this relevant only to buyers whose vehicle has the different 6×135 pattern.

A forged 6061-T6 billet construction distinguishes ezaccessory’s four-adapter set, which converts a 6×135 vehicle pattern to 5×5 (5×127). It enables compatible five-lug wheels on listed six-lug applications, including F-150 and Lincoln Navigator uses, with the target wheel pattern clearly specified.

The 6×135-to-5×5 conversion allows a vehicle with the listed six-lug pattern to mount a wheel using the specified five-lug pattern. The product description names F-150, Expedition, and Lincoln Navigator applications, and notes use with 2007-and-after Jeep Wrangler wheels. Aircraft-quality forged 6061-T6 billet and CNC machining are stated construction details, while the four adapters are sold as two pairs. Buyers should match both the vehicle and wheel patterns to this conversion.

Pros
  • Converts 6×135 vehicle pattern to 5×5 (5×127)
  • Four adapters supplied as two pairs
  • Forged 6061-T6 billet construction
  • CNC machined
Cons
  • The conversion is specific to 6×135 vehicles and 5×5 wheels.

Skip it if you have a 6×5.5 vehicle; FLYCLE’s B0CQCCMNFS adapter is specified for that vehicle pattern.

This fits buyers converting a listed 6×135 vehicle, such as an F-150 or Navigator application, to 5×5 wheels. Its patterns are specific, so other six-lug configurations fall outside the stated conversion.

Yukon GM 12-Bolt 5-Lug Kit

#10

10. Yukon GM 12-Bolt 5-Lug Kit

Best for: Classic GM 12-bolt rear conversion.

Why it ranks #10: This is a rear axle conversion kit for 1965–1969 GM 12-bolt trucks, not a wheel adapter for fitting five-lug wheels to a six-lug vehicle.

Yukon Gear & Axle identifies this as a five-lug conversion kit for 1965–1969 GM 12-bolt trucks, with a rear axle kit included. That application-specific focus makes it a different kind of conversion from a bolt-on wheel-pattern adapter: the listing centers on the rear axle assembly for a classic truck.

The included rear axle kit and stated 1965–1969 GM 12-bolt truck application give classic-truck owners a defined starting point for a five-lug rear conversion. Yukon also identifies steel construction and describes high-quality alloys and heat-treatment technology, connecting the material and manufacturing details to axle strength. Because the listing specifies a particular rear axle family and model-year range, buyers need to match that exact application rather than treat it as a universal 6-lug wheel adapter.

Pros
  • Five-lug conversion kit for GM 12-bolt trucks
  • Specified for 1965–1969 applications
  • Rear axle kit included
  • Steel construction identified
Cons
  • Application is limited to 1965–1969 GM 12-bolt trucks.

Skip it if you need a wheel-pattern adapter for a modern 6×5.5 vehicle; this kit is for a classic GM 12-bolt rear axle.

This suits a classic GM truck owner converting the rear axle on a 1965–1969 12-bolt application. It is not presented as a general wheel adapter, so the axle family is the key boundary.

Avoid the bolt-pattern and hub-fit trap

A matching lug count does not make an adapter compatible; the vehicle-side and wheel-side bolt patterns must both match exactly. For example, 6×5.5-to-5×4.5 products cannot fit 5×5 wheels, while a 6×5.5-to-5×5 adapter does not fit 5×5.5 wheels. The listings also show why center bore matters: the YIZBAP and SCITOO 5×4.5 products specify a 108mm bore, while the ECCPP 5×4.75 product lists 78.1mm.

Verify the vehicle hub bore and wheel center bore against the product requirements rather than relying on a vehicle name or lug count alone. Check stud thread as well: several products list 14×1.5, while PHILTOP specifies M14x1.5.

Vehicle fitment lists are useful starting points, not a substitute for confirming the exact year, trim, hub, and wheel.

Account for bolt length and added spacing

A thick adapter can create clearance and installation issues if vehicle studs protrude beyond its mounting face or the wheel lacks space for them. PHILTOP specifically warns that vehicle bolts longer than the adapter thickness may need to be cut; do not assume that warning applies identically to every product, but use it as a cue to inspect the installed geometry before assembly. Several options in this roundup are 2 inches thick, so they also move the wheel outward by that listed amount.

That change can affect clearance to the fender, suspension, and other nearby parts, but the product data does not establish clearance for a particular vehicle or wheel combination. Check fitment with the actual wheel and tire, follow the manufacturer’s installation instructions and torque requirements, and seek qualified help if you cannot verify safe stud engagement or clearance.

How to Choose a 6-to-5-Lug Wheel Adapter

Match both bolt patterns

Start by matching the vehicle pattern to the wheel pattern, because these products do not convert to one universal five-lug size. The roundup includes 6×5.5-to-5×4.5 options, 6×5.5-to-5×5, 6×5.5-to-5×5.5, and a two-piece 6×5.5-to-5×4.75 set. The ezaccessory product instead starts at 6×135 and converts to 5×5, so it suits a different vehicle-side pattern.

Buyers with common 6×5.5 hubs should select according to their actual wheel’s five-lug pattern; buyers with 6×135 hubs should consider only a matching conversion. Never select based only on the phrase “six lug to five lug.”

Check thickness and fitment details

Look for an adapter thickness and vehicle application that match your setup, then confirm stud length and nearby wheel clearance. Multiple products specify 2 inches, including the ECCPP 6×5.5-to-5×4.5 and PHILTOP 6×5.5-to-5×5.5 options. That thickness is a defined part of the conversion, not a universal fit guarantee.

PHILTOP also notes that vehicle bolts extending beyond the adapter may need cutting, so buyers who cannot verify stud clearance should pause before installation. Broad application lists may help owners of Silverado, Tahoe, or Sierra vehicles identify candidates, while exact year, trim, and hub verification should decide the final choice.

Favor the listed application that actually matches your vehicle, not the longest compatibility list.

Compare bore, studs, and adapter count

Choose a product whose hub bore and thread specifications match your hardware, and check that the set includes enough adapters for your intended installation. The YIZBAP and SCITOO 6×5.5-to-5×4.5 listings specify a 108mm bore and 14×1.5 studs; PHILTOP lists a 108mm bore and M14x1.5 thread. ECCPP’s 5×4.75 option lists a 78.1mm center bore and comes as two pieces, unlike several four-piece sets.

Buyers requiring four adapters should avoid assuming that a two-piece kit is a complete vehicle set. Buyers with confirmed matching hubs and studs can use these details to narrow the selection, but should verify the complete mounting requirements before purchase.

Which 6-to-5-lug adapter fits my setup?

Choose by the exact patterns first. For a 6×5.5 vehicle and aftermarket 5×4.5 wheels, the ECCPP 6×5.5 to 5×4.5 Adapters are the leading broad-fit option; YIZBAP 6×5.5 to 5×4.5 Adapters offer clearly listed 108mm bore and 14×1.5 studs. If your wheels are 5×5, consider ECCPP 6×5.5 to 5×5 Adapters; for 5×5.5, compare ECCPP 6×5.5 to 5×5.5 Adapters and PHILTOP 6×5.5 to 5×5.5 Adapters.

The SCITOO set is another 5×4.5 choice with a long listed application range. Choose ezaccessory 6×135 to 5×5 Adapters only for a 6×135 vehicle.

Yukon GM 12-Bolt 5-Lug Kit is an axle conversion, not a wheel adapter. Verify fitment and clearance before installation.

Frequently Asked Questions

How do I confirm that my vehicle and aftermarket wheel bolt patterns match an adapter?

Confirm both patterns from reliable vehicle and wheel specifications before choosing an adapter. Match the vehicle’s lug pattern to the adapter’s vehicle-side pattern, then match the adapter’s wheel-side pattern to the aftermarket wheel. Also verify the exact vehicle fit, center bore, and stud specifications; do not assume similar-looking patterns are interchangeable.

Do wheel adapters affect wheel offset, clearance, or handling?

Yes. An adapter moves the wheel outward by its thickness, changing its effective position and potentially affecting clearance to bodywork, suspension, or other components. Handling effects can vary with the vehicle, wheel, tire, and setup.

Check clearance at steering lock and through suspension travel, and confirm the complete combination is appropriate for your vehicle.

What installation checks should I make before driving with wheel adapters?

Before driving, confirm the adapter fits flush against the hub and that its pattern, bore, studs, and wheel-side fit are correct. Follow the adapter maker’s installation instructions and specified torque procedures, check that the wheel turns without contact, and inspect for looseness or interference. Do not drive if fitment or clearance is uncertain.

Is an axle conversion kit the same as a wheel adapter?

No. A wheel adapter connects a vehicle hub to a wheel with a different bolt pattern, while the listed Yukon kit is a GM 12-bolt axle conversion. Treat them as different types of parts and confirm which component your project requires before selecting a product.

Can I use a 6×5.5 adapter on a 6×135 vehicle?

No, not based on the listed patterns: 6×5.5 and 6×135 are different vehicle-side patterns. The ezaccessory listing is for a 6×135 vehicle mounting 5×5 wheels; the 6×5.5 options are for vehicles with that pattern. Confirm your exact hub and wheel specifications before choosing.

Final Words

Choose by the exact vehicle-side and wheel-side patterns first, then verify the vehicle fit, wheel specifications, and clearance. For a 6×5.5 vehicle with aftermarket 5×4.5 wheels, the ECCPP adapters lead this selection; consider the other listed patterns only when they match your setup. The Yukon product is an axle conversion, not a wheel adapter.

Do not assume a fit based on vehicle name alone.
