Best Wheel Spacers For Tractors for Specific Axle Fitment

#1 · Best Overall

1. BORA JD 3032E

• Material: Aluminum
• Size: 3.0"
• Compatible with Vehicle Type: Tractor

Best for: John Deere 3032E both axles.

Why it ranks #1: Designed for the John Deere 3032E and both axles, it specifies a 6×6 pattern, 4.625-inch center bore, and 14×1.5 hardware.

A stated fit on both axles makes this 3-inch BORA set a single application-specific option for John Deere 3032E owners widening front and rear stance. The 6×6 bolt pattern, 4.625-inch center bore, and 14×1.5 bolts for tapped holes specify its mounting details.

The aluminum spacers move wheels outward to create a wider stance, which BORA associates with better balance and traction on and off road. The 3-inch thickness defines a substantial spacing change, while the 6×6 bolt pattern and 4.625-inch center bore target the 3032E. BORA describes a bolt-on installation at the factory hub, and the product fits both axles. That broad axle coverage can simplify a matched setup, but the listed fit remains specific to the John Deere 3032E.

Skip it if you need rear spacers for a John Deere 4066R; BORA's 4066R rear set is made for that axle and tractor.

This set suits 3032E owners who want a matching spacer application across both axles and a 3-inch stance change. Its tractor-specific fit means it is not a general-purpose choice for other John Deere models.

#2 · Both-Axle Fit

2. BORA JD 2038R

• Material: Aluminum
• Size: 3.0"

Best for: John Deere 2038R both axles.

Why it ranks #2: Its listed fit covers both axles of the John Deere 2038R, with a 6×6 bolt pattern, 4.625-inch center bore, and 3-inch size.

A both-axle fit makes this 3-inch BORA spacer set a coordinated stance option for John Deere 2038R owners. Its 6×6 bolt pattern, 4.625-inch center bore, and 14×1.5 hardware identify the specified mounting arrangement, while the aluminum construction keeps the application tractor-specific.

The spacers push wheels outward to create a wider stance, which BORA says can improve balance and traction on and off road. At 3 inches thick, they provide a defined amount of spacing, and the stated 6×6 pattern with a 4.625-inch center bore targets the 2038R. The product is listed for both axles, so one application-specific set can address front and rear positions. A factory-hub bolt-on installation is described, but the fitment remains tied to this John Deere model.

Skip it if you need a 2.5-inch front-axle set for a Kubota L Series; BORA's L Series front spacers are specified for that fitment.

This fits 2038R owners planning a 3-inch stance change at both axles, with a factory-hub bolt-on approach. Treat the tractor-specific fit and substantial spacing as the key decision boundaries.

#3 · Front-Axle Pick

3. BORA Kubota L Front

Best for: Kubota L Series front axle.

Why it ranks #3: Made for the front axle of listed Kubota L Series models, it specifies a 6×6 pattern, 4.625-inch center bore, and 14×1.5 hardware.

A 2.5-inch spacer thickness distinguishes this BORA set for the front axle of Kubota L Series tractors. Its 6×6 bolt pattern, 4.625-inch center bore, and 14×1.5 hardware identify the mounting arrangement, while the model list spans numerous L Series tractors from the L2350 through the L6060.

The aluminum spacers push the front wheels outward for a wider stance, which BORA says can improve balance and traction. The stated 6×6 pattern and 4.625-inch center bore give the fitment a defined target, while nuts and studs are listed alongside 14×1.5 hardware. This front-axle set is specified for numerous Kubota L Series models, helping owners select a position-specific option rather than treating front and rear fitments as interchangeable. Its 2.5-inch thickness sets the amount of outward spacing.

Skip it if you need a rear-axle set for a Kubota L Series tractor; BORA's L Series rear spacers are specified for that position.

Pick this for a listed Kubota L Series tractor when the front axle needs additional spacing. The 2.5-inch width and front-specific fitment matter when coordinating it with a separate rear set.

#4 · Rear-Axle Pick

4. BORA Kubota L Rear

• Material: Aluminum
• Size: 2.0"
• Compatible with Vehicle Type: Tractor

Best for: Kubota L Series rear axle.

Why it ranks #4: This rear-axle spacer names numerous Kubota L Series models and includes nuts and bolts, with a 6×170 pattern and 2-inch size.

A 2-inch spacer thickness and rear-axle-specific fitment make this BORA set a substantial stance option for listed Kubota L Series tractors. Its 6×170 bolt pattern, 5.325-inch center bore, and included nuts and bolts address the rear mounting layout rather than asking buyers to adapt a general-purpose spacer.

The aluminum spacers move the rear wheels outward, with BORA associating the wider stance with improved balance and traction on and off road. The specified fit covers numerous L Series models, including L2501, L3301, and L3901, while the 6×170 pattern and 5.325-inch center bore define the mounting interface. Nuts and bolts are included, and the design combines studs with tapped holes for mounting. Because this set is for the rear axle, it does not provide a front-axle spacer solution.

Skip it if you need front-axle spacers for a Kubota L Series tractor; BORA's L Series front-axle set serves that position.

This is for Kubota L Series owners widening the rear stance, including listed models such as the L2501 and L3301. Keep its rear-only application in mind when planning a complete front-and-rear setup.

#5

5. BORA JD 1025R

• Material: Aluminum
• Size: 1.5"
• Compatible with Vehicle Type: Tractor

Best for: John Deere 1025R stance upgrade.

Why it ranks #5: Specifically built for John Deere 1025 and 1025R tractors, it fits both axles and lists a 5×4.5 pattern with a 1.5-inch size.

A tractor-specific 5×4.5 bolt pattern and matching hardware make this 1.5-inch BORA spacer set a direct fitment option for John Deere 1025/1025R owners. It fits both axles, so the same set can widen the stance at either end rather than serving only one axle.

The aluminum spacers push the wheels outward to create a wider stance, which BORA says can help improve balance and traction on and off road. Their 5×4.5 bolt pattern, 3.15-to-3.12 center-bore fitment, and matching 12×1.25 hardware target the listed 1025/1025R application. The true bolt-on setup mounts directly to the factory hub, simplifying installation compared with a design requiring hub modification. The 1.5-inch size offers less outward extension than wider options in this roundup.

Skip it if you need a 3-inch rear-axle spacer for a John Deere 2025R; BORA's 2025R rear set provides that application.

Choose this for a John Deere 1025 or 1025R owner seeking a bolt-on stance change at either axle. The 1.5-inch thickness and tractor-specific bolt pattern define its fit and spacing limits.

#6

6. BORA JD 2025R Rear

• Material: Aluminum
• Size: 3
• Compatible with Vehicle Type: Tractor, UTV

Best for: John Deere 2025R rear stability.

Why it ranks #6: Designed for the John Deere 2025R rear axle, it lists a 6×6 pattern, 4.625-inch center bore, and 3-inch size.

A 3-inch rear spacer moves the wheels outward on the John Deere 2025R, making this BORA set the widest stated choice for that tractor in this roundup. Its 6×6 pattern and 4.625-inch center bore target the 2025R rear axle rather than a universal tractor fit.

BORA specifies a hub- and wheel-centric fit using the 6×6 bolt pattern and 4.625-inch center bore, which focuses the installation on the John Deere 2025R rear axle. The 3-inch thickness creates a wider stance; the supplied description links that change to improved stability on uneven terrain and reduced rollover risk. The spacers are aluminum, and the bolt-on format attaches directly to the factory setup. Since this product is designated for the rear axle, buyers seeking front spacing need another application-specific set.

Skip it if you want spacers for both axles of a John Deere 3032E; BORA's 3032E set fits both axles.

This suits 2025R owners seeking a wider rear stance for work on uneven terrain. The 3-inch thickness is substantial, but its stated fit is restricted to the 2025R rear axle.

#7

7. BORA JD 4066R Rear

• Material: Aluminum
• Size: 3.0"
• Compatible with Vehicle Type: Tractor

Best for: John Deere 4066R rear stance.

Why it ranks #7: This rear-axle option is specified for the John Deere 4066R, with an 8×8 pattern, 6-inch center bore, and 3-inch size.

An 8×8 bolt pattern and 6-inch center bore set this 3-inch BORA spacer pair apart for the rear axle of a John Deere 4066R. The rear-specific fit and factory-hub bolt-on design target owners widening the back of this tractor without changing the front axle.

The aluminum spacers push the rear wheels outward, with BORA linking the wider stance to improved balance, traction, and on- or off-road performance. The 3-inch thickness gives a clearly defined spacing change, while the 8×8 pattern and 6-inch center bore identify the intended mounting interface. Tapped holes and 14×1.5 bolts are specified, and the bolt-on approach mounts directly to the factory hub. The set is listed for the 4066R rear axle only, so it is not a complete all-axle kit.

Skip it if you need a 4-inch rear spacer for a John Deere 3039R; BORA's 3039R rear set provides that thicker option.

This is for 4066R owners wanting a 3-inch rear stance change with a factory-hub bolt-on arrangement. Its 8×8 pattern, 6-inch center bore, and rear-only position define the fit boundary.

#8

8. BORA JD 3039R Rear

• Material: Aluminum
• Size: 4.0"
• Compatible with Vehicle Type: Tractor

Best for: John Deere 3039R wider rear.

Why it ranks #8: Made for the John Deere 3039R rear, it specifies an 8×8 pattern, 6-inch center bore, and a comparatively thick 4-inch size.

Four inches of spacing gives this BORA set the largest stated extension in this roundup, specifically for the rear axle of a John Deere 3039R. Its 8×8 bolt pattern, 6-inch center bore, and tapped-hole hardware match that focused application rather than a general tractor axle.

BORA says the wider stance can help improve balance and traction for on- and off-road operation, while the 4-inch thickness makes the amount of outward movement explicit. The 8×8 pattern and 6-inch center bore specify the rear mounting interface for the John Deere 3039R, and the supplied description calls the design a direct factory-hub bolt-on. Aluminum construction and 14×1.5 bolts for tapped holes round out the stated setup. This is a rear-only application, so it does not address front spacing.

Skip it if you want a 3-inch rear spacer for a John Deere 4066R; BORA's 4066R rear set has that application and thickness.

Choose this for a 3039R owner deliberately seeking a 4-inch rear stance change. That extension is substantial, and the rear-only fitment and 8×8 interface should guide the installation plan.

#9

9. AR-PRO 3/4-Inch Kit

• Material: Metal
• Size: 3/4" Bore
• Compatible with Vehicle Type: Lawn Tractor, Riding Mower

Best for: Lawn tractor axle spacer kit.

Why it ranks #9: A metal spacer kit for lawn tractors and riding mowers, it has a 3/4-inch bore and includes 1/2-inch and 1/4-inch sleeves.

A 3/4-inch bore paired with a metal spacer body gives this AR-PRO kit a straightforward fit target for standard lawn tractor and riding mower axles. Its mixed sleeve set lets owners combine the included 1/2-inch and 1/4-inch extensions when adjusting wheel spacing for mower applications.

The high-strength metal construction is specified as stronger than plastic alternatives and intended to handle demanding mower use, making it the practical choice where load-bearing capacity matters. A 3/4-inch inner diameter targets standard lawn tractor and riding mower axles, while the combo pack supplies four 1/2-inch and four 1/4-inch extension sleeves. That mix offers spacing options without requiring a separate sleeve size for every adjustment, though compatibility is stated for lawn tractors and riding mowers rather than larger tractors.

Skip it if you need a model-specific agricultural tractor spacer; BORA's John Deere 1025/1025R kit is specified for that tractor.

This kit suits lawn tractor and riding mower owners who want metal spacers with two sleeve lengths for axle-spacing adjustments. Its stated 3/4-inch bore and mower-focused compatibility make it a poor match for other tractor classes.

#10

10. Rugged Kubota 4×110

Best for: Kubota RTV tire-clearance setup.

Why it ranks #10: This 2-inch, 4×110 spacer lists Kubota RTV-X900 and RTV-XG850 applications, making it a utility-vehicle option rather than a tractor-specific pick.

Two inches of spacing lets this Rugged 4×110 set widen a compatible Kubota's stance while creating room for larger tires or rims. Its anodized surface adds corrosion resistance, a useful consideration for utility vehicles exposed to working conditions where the spacer finish may encounter moisture.

Rugged identifies this spacer for Kubota applications and says the added clearance can accommodate wider, larger, or high-traction tires. That makes the 2-inch spacing relevant to owners changing tire or rim dimensions, as well as those seeking a wider stance. The product information also lists 2014–2023 RTV-X900 and 2018–2022 RTV-XG850 Sidekick applications, front and rear. Anodized surface treatment is specified for added corrosion resistance, but the supplied details do not identify installation hardware or a broader tractor fit range.

Skip it if you need a tractor-specific spacer with listed mounting hardware; BORA's John Deere 1025/1025R set includes matching hardware.

Consider this for a listed Kubota RTV owner seeking tire clearance or a wider stance, especially when changing to larger or higher-traction tires. Its 4×110 pattern and stated RTV fitments are the key boundaries.
