Best Rear Brake Conversion Kit for Ford, GM and ATV Builds

#1 · Best Overall

1. Speedway Motors Ford Kit

Best for: Ford 8- or 9-inch conversion builders.

Why it ranks #1: The listing explicitly fits Ford 8- or 9-inch rear ends and describes a complete bolt-on kit, making its axle coverage clear.

The Speedway Motors kit covers both Ford 8- and 9-inch rear ends, giving builders two named axle families to consider in one conversion listing. Its title calls it a complete, bolt-on rear-end kit, emphasizing a conversion format rather than a component-by-component specification.

The Ford 8- or 9-inch compatibility stated in the title helps buyers begin with rear-end identification, while the bolt-on description frames installation around attaching the kit to the axle assembly. Speedway Motors calls it a complete kit and positions it for increased stopping power, but the supplied details do not enumerate the included brake parts or state axle measurements. That makes the axle-family match clear while leaving component-level planning less defined.

Skip it if you need an itemized parts list or axle measurement limits before planning installation; those details are not supplied here.

A builder with a Ford 8- or 9-inch rear end seeking a bolt-on conversion may find the stated application useful. The listing's lack of component-level detail is a boundary for parts planning.

#2 · Parking Brake Cables

2. GELUOXI Ford Kit

• Compatible with Vehicle Type: Car

Best for: Ford 8- or 9-inch axle owners.

Why it ranks #2: It targets Ford 8- and 9-inch small-bearing axles and includes parking-brake cables; the listing also specifies wheel and shim considerations.

Three shim options let this GELUOXI kit adjust brake spacing to the rear axle, a useful detail for Ford 8- and 9-inch small-bearing conversions. It also includes three flange options, giving the installer choices for axle-flange configurations while replacing rear drums with discs.

The adjustable shims help set brake spacing to the axle, while the three flange options address differing rear axle flange configurations. The kit is specified for Ford 8- and 9-inch small-bearing rear ends, so it is aimed at a particular axle family rather than a universal conversion. Installation requires axle removal, but the supplied note says welding and fabrication are not required. Wheel clearance is a firm consideration: the kit requires 14-inch disc-brake wheels or rims 15 inches and larger.

Skip it if you cannot remove the axles or run the specified wheel clearance; this kit requires both for installation and use.

Ford 8- or 9-inch small-bearing axle owners who want a disc conversion with shim and flange choices should consider this kit. Plan for axle removal and check that the wheels meet its stated clearance requirement.

#3 · Built-In E-Brake

3. JEGS GM A-Body Kit

• Compatible with Vehicle Type: Car

Best for: 1964–1972 GM A-body owners.

Why it ranks #3: It fits many GM 10- and 12-bolt rear axles and A-body cars, with 11-inch rotors, loaded calipers, hoses, hardware, and an emergency-brake kit.

A built-in emergency brake in the loaded calipers gives this JEGS kit a practical feature for GM A-body drum-to-disc conversions. It is specified for 1964–1972 A-body cars and most 10- and 12-bolt rear axles, with a bolt-on installation approach.

The 1964–1972 GM A-body application and 10- or 12-bolt axle specification narrow the intended fit, while the dual 5 x 4.750-inch and 5 x 4.500-inch rotor bolt patterns address two listed wheel patterns. Plain 11-inch rotors, rubber hoses, loaded calipers, hardware, and a parking/emergency brake kit are included. The kit is described as bolt-on for standard shock applications whether both shocks sit forward of or behind the axle housing.

Skip it if you have a nonstandard shock arrangement; the listing specifies both shocks forward of or behind the rear axle housing.

GM A-body owners with a matching 10- or 12-bolt axle can consider this bolt-on kit, particularly when the built-in emergency brake and dual rotor patterns suit the project. Standard shock placement remains a fit boundary.

#4 · GM Axle Coverage

4. Speedway Motors GM Kit

• Compatible with Vehicle Type: Car, Truck, Van

Best for: GM 10- or 12-bolt axle projects.

Why it ranks #4: This bolt-on dual-pattern kit is specifically listed for GM 10- and 12-bolt applications, though the supplied details provide fewer component specifics.

The Speedway Motors kit is specifically titled for GM 10- and 12-bolt rear ends, making axle-family identification its clearest selection point. Its dual-pattern bolt-on format gives builders a conversion option centered on those housings without relying on a broad universal-fit claim.

The GM 10- and 12-bolt designation narrows the intended application to those rear-end families, helping buyers screen out unrelated axle types before planning a conversion. The dual-pattern bolt-on description points to a mounting approach based on bolting components in place rather than a fabrication-oriented format. The listing does not provide component details or a vehicle-year range, so shoppers should use the axle specification as the available fit guide and not infer included parts or broader compatibility.

Skip it if you need a listed component inventory or year-by-year application; this listing provides neither for narrowing the conversion.

A builder already identifying a GM 10- or 12-bolt rear end may value the dual-pattern bolt-on format. The listing leaves component contents and year-specific applications unspecified, so those details remain a boundary.

#5

5. Right Stuff GM Truck Kit

Best for: Select 5-lug Chevy and GMC trucks.

Why it ranks #5: Its stated fit covers select 2WD Chevy and GMC trucks with GM 10- or 12-bolt rear ends and a 5-lug pattern.

A 5 x 5-inch wheel bolt pattern makes this Right Stuff kit a clearly specified choice for select Chevy and GMC truck conversions. Its stated GM 10- and 12-bolt rear-end compatibility further narrows the intended axle group, avoiding a one-size-fits-all claim.

The kit is listed for select 1973–1991 Chevy and GMC 2WD trucks, tying the conversion to a stated vehicle range and drivetrain. Its GM 10- or 12-bolt rear-end specification identifies the axle family, while the 5 x 5-inch bolt pattern helps screen for wheel compatibility. Standard rotors and natural calipers are also specified, giving buyers concrete component details when comparing the kit with other configurations.

Skip it if you need a kit for a different wheel pattern or a vehicle outside the listed select 2WD truck applications.

Owners of a listed Chevy or GMC 2WD truck with a GM 10- or 12-bolt rear end and 5 x 5-inch wheels are the intended audience. The select-application limitation matters before choosing it.

#6

6. Mixizap Ford 9-Inch Kit

• Compatible with Vehicle Type: Truck

Best for: Ford 9-inch rear-end owners.

Why it ranks #6: It is designed for Ford 9-inch axles and lists axle-offset and flange-diameter limits, but its fit is narrower than the Ford 8- and 9-inch options.

A serviceable design and compatibility with Ford 9-inch axles are the key identifiers for this Mixizap rear disc kit. Its specified axle-offset and flange limits give builders practical measurements to check while planning a bolt-on conversion.

The kit is listed for Ford 9-inch axles with minimum axle offsets of 2-3/8 to 2-1/2 inches and a maximum flange diameter of 6 1/4 inches. Those measurements make axle inspection important before installation, rather than relying only on the Ford 9-inch label. The listing describes the kit as bolt-on and serviceable, which supports a conversion approach intended for routine service without claiming unlisted component contents or broader fitment.

Skip it if you cannot verify the stated axle offset and flange diameter; both measurements define this kit's Ford 9-inch fit.

Ford 9-inch owners whose axle measurements fall within the listed offset and flange limits may appreciate a serviceable bolt-on format. Measure those axle details first, since the application is not unrestricted.

#7 · Drilled Rotors

7. Voyagrise GM Axle Kit

• Compatible with Vehicle Type: Car, Truck

Best for: 5-on-5 GM axle conversion builders.

Why it ranks #7: The kit targets GM 10- and 12-bolt rear axles with a 5-on-5 pattern and includes drilled, slotted rotors plus calipers, pads, hoses, and hardware.

Cross-drilled and slotted 11.5-inch rotors distinguish this Voyagrise kit for GM 10- and 12-bolt rear axle conversions. Its stated 5-on-5 bolt circle and 1964–1987 application give buyers concrete axle and wheel-pattern criteria for screening fit.

The 5-on-5 bolt circle and GM 10- or 12-bolt rear-axle description narrow the intended conversion, while the 1964–1987 range adds a vehicle-year reference. The kit includes rotors, backing plates, bearings, seals, calipers, pads, brake hoses, brake tabs, and a caliper bracket, so the listed parts cover multiple conversion needs. The 11.5-inch drilled and slotted rotors have an anodized finish described as helping prevent rust.

Skip it if you need a different bolt circle; this kit is specified for a 5-on-5 pattern and GM 10- or 12-bolt rear axle.

A builder converting a listed 1964–1987 GM 10- or 12-bolt rear axle with a 5-on-5 pattern gets a detailed component set and drilled, slotted rotors. The bolt-circle and axle limits are central.

#8

8. Fizzvex Chevy Truck Kit

Best for: Eight-lug Chevy truck conversions.

Why it ranks #8: It lists several Chevy C- and K-series applications and supplies 8-lug rotors, calipers, pads, hoses, and mounting hardware.

The included 8-lug, 12.5-inch GM rotors make this Fizzvex conversion a defined option for listed Chevy truck applications. Its component package also names brackets, calipers, pads, hoses, and mounting hardware, helping buyers assess the scope of the conversion.

Fizzvex lists several C20, C30, G20, and K20/K30 applications across specified model years, giving truck owners a concrete compatibility starting point. The 8-lug 12.5-inch rotors pair with steel-piston calipers and semi-metallic pads, while laser-cut, drilled-and-tapped brackets and zinc-coated Grade 8 bolts address mounting. Inner hub seals, caliper pins, rubber flex hoses, banjo bolts, copper washers, and anti-rattle clips are also itemized, making the included installation components clear.

Skip it if you need a conversion for an unlisted vehicle or axle; the stated fitment is limited to specific Chevy models and years.

Owners of the listed Chevy truck and van models who need an 8-lug rear conversion can use the detailed parts list to plan the job. Application is limited to the stated models and years.

#9

9. D-ETEGNIK C10 Kit

• Compatible with Vehicle Type: Car

Best for: Six-lug 1963–1970 C10 owners.

Why it ranks #9: This kit is tailored to 6-lug C10 trucks and also lists Suburban and 2WD Blazer fitment, with rotors, calipers, brackets, and hoses.

The six-lug configuration and 1963–1970 Chevy C10 fitment make this D-ETEGNIK kit unusually specific for classic truck buyers. The listing also extends compatibility to GMC15 trucks and certain Suburban and 2WD Blazer applications.

The stated Chevy C10 and GMC15 truck years give owners a defined vehicle range, while six-lug compatibility addresses the intended wheel pattern. The kit is described as a complete rear drum-to-disc conversion and lists rotors, calipers, brackets, brake hoses, and necessary hardware. That named component set helps with job planning, and the additional Suburban and 2WD Blazer fitments broaden the listed applications beyond C10 trucks without turning the kit into a universal option.

Skip it if you have a different vehicle year or wheel pattern; the listed applications center on 1963–1970 trucks and six-lug wheels.

Owners of a listed 1963–1970 C10, GMC15, Suburban, or 2WD Blazer with six-lug wheels are the intended buyers. Its specific application and wheel-pattern limits should guide selection.

#10

10. SuperATV Honda Kit

• Compatible with Vehicle Type: Does NOT FIT: 2×4 Models | Models with drum…

Best for: Honda solid-axle 4×4 ATV riders.

Why it ranks #10: It converts rear drums on specified solid-axle Honda 4×4 utility ATVs, so it suits an ATV buyer but not the listed car and truck applications.

Compatibility with Honda Foreman 500 and 520 and Rancher 420 models gives this SuperATV kit a defined ATV audience. It replaces a drum-brake setup on solid-axle Ranchers, offering a disc conversion for riders whose machine and rear-brake arrangement match the stated application.

The listed Foreman and Rancher applications help owners identify whether this is the relevant Honda 4×4 kit, while the solid-axle restriction rules out some configurations. SuperATV says installation needs no welding or modifications and can be completed with everyday hand tools, a practical advantage for a DIY conversion. It uses common brake pads, including current RDBK pads or OE replacement pads, which gives owners those stated pad options for ongoing service.

Skip it if you own a 2×4 Honda or a swing-arm drum-brake model; this kit is limited to specified 4×4 applications.

Owners of listed Honda 4×4 Foreman or Rancher models with a matching solid axle can consider this DIY-oriented conversion. It is not for 2×4 machines or swing-arm drum setups, so the rear configuration is decisive.
