Best G Body Disc Brake Conversion Kit for GM Rear Axles

#1 · Best Overall

1. Inline Tube Rear Disc Conversion

• Compatible with Vehicle Type: Car

Best for: Factory-style G-Body conversion.

Why it ranks #1: Specifically covers 1978–87 GM G-body rear axles and includes slotted rotors, loaded calipers, parking-brake parts, hoses and hardware.

Cross-drilled and slotted rotors arrive with loaded, pad-equipped calipers, giving this Inline Tube kit a more complete factory-style rear-disc conversion package. Its included cables, lines, hoses, brackets, shims, and hardware support the changeover workflow, while the integrated parking-brake components preserve that function in a conversion intended for specified GM G-Body applications.

The supplied single-piston calipers come loaded with pads, so the package includes more than bare calipers for the rear conversion. Cross-drilled and slotted rotors are paired with caliper brackets, shims, lines, hoses, and mounting hardware, bringing many of the listed installation components together. Parking-brake cables and hose clips are included as well. Fit has firm limits: the listing specifies a 7.5-inch rear axle and wheels at least 15 inches in diameter.

Skip it if you have a rear axle other than the specified 7.5-inch type; SKAUTOPT's listing covers a broader stated vehicle range.

Choose this Inline Tube kit for a factory-style rear conversion when the vehicle has the specified 7.5-inch axle and at least 15-inch wheels. Its loaded calipers and included parking-brake parts suit buyers seeking a broadly equipped package.

#2 · Best 10-Bolt Match

2. JEGS 10-Bolt Rear Kit

• Compatible with Vehicle Type: Car

Best for: JEGS standard e-brake kit.

Why it ranks #2: Names 1978–88 GM 10-bolt G-body fitment, 11-inch multi-pattern plain rotors, rubber hoses, mounting hardware and an e-brake.

An 11-inch GM rotor and standard-kit configuration with an e-brake make this JEGS package distinct for buyers seeking a conventional G-Body conversion bundle. It lists plain rotors, raw calipers, brackets, flanges, rubber brake hoses, and mounting hardware, with stated applications covering 1978–1988 GM G-Body and 1982–1992 GM F-Body vehicles.

JEGS identifies this as a GM 10-bolt rear-disc conversion for the stated G-Body and F-Body years, giving buyers a specific axle and vehicle range to compare against their car. The 11-inch plain rotors are multi-pattern, while rubber hoses, brackets, flanges, and mounting hardware are listed for the conversion. The calipers are described as raw, unlike loaded calipers supplied with pads; buyers should account for that distinction when planning parts and installation.

Skip it if you want drilled and slotted rotors; the Fizzvex G Body S10 kit lists that rotor style and emergency-brake calipers.

Choose the JEGS standard kit if your GM 10-bolt G-Body or listed F-Body application suits its stated range and you prefer plain, multi-pattern rotors. Its raw calipers mean pad preparation is a separate installation consideration.

#3 · Best Fitment Notes

3. SKAUTOPT 10-Bolt Kit

• Compatible with Vehicle Type: Cars

Best for: Axle-pull installation planners.

Why it ranks #3: Specifies a 10-bolt rear conversion, 15-inch-or-larger disc wheels and axle removal, plus 11-inch drilled-and-slotted rotors and emergency-brake cables.

This SKAUTOPT kit explicitly states that installation requires pulling the axles and using disc-brake wheels at least 15 inches in diameter, making two key planning constraints clear upfront. It includes 11-inch drilled and slotted rotors, emergency-brake calipers, cables, rubber hoses, and hardware across its listed Buick, Chevrolet, Pontiac, and Olds applications.

The 15-inch-or-larger wheel requirement gives buyers a clear threshold to check before starting, while the axle-pull note signals a significant installation step. The two 11-inch drilled and slotted rotors have 5-on-4.5-inch and 4.75-inch bolt patterns. Emergency-brake calipers, cables, rubber hoses, and complete mounting hardware are included, bringing key conversion parts together. Its listed applications cover selected Skylark, Camaro, El Camino, Malibu, Monte Carlo, Firebird, Le Mans, Tempest, and Olds years.

Skip it if you cannot pull the axles or have wheels smaller than 15 inches; Inline Tube DBK1012GX also specifies 15-inch wheels but lists a 7.5-inch axle.

This SKAUTOPT package suits a hands-on conversion plan where axle removal is manageable and the vehicle has at least 15-inch wheels. Check the stated model-year applications and both rotor bolt patterns before beginning the installation.

#4 · Best Listed Package

4. Fizzvex Drilled Rotor Kit

Best for: Multi-model drilled-rotor kit.

Why it ranks #4: Lists 11-inch drilled-and-slotted rotors, calipers with built-in emergency brakes, cables, rubber hoses and complete mounting hardware.

Two 11-inch drilled and slotted rotors with 5-on-4.5-inch and 4.75-inch bolt patterns give this Fizzvex kit a concrete fitment feature for its listed applications. The package also includes calipers with built-in emergency brakes, cables, hoses, and mounting hardware, supporting a rear-disc conversion with parking-brake components.

The paired rotor bolt patterns are specified as 5-on-4.5-inch and 4.75-inch, giving buyers concrete wheel-pattern details to compare with their setup. Each rotor measures 11 inches, and the included calipers have built-in emergency brakes; matching cables, rubber hoses, and complete mounting hardware are listed. The stated applications span Buick Skylark, several 1978–1987 Chevrolet models, and selected Camaro, Firebird, Olds, and Pontiac years, so check the exact listed model range before planning installation.

Skip it if you need explicit wheel-diameter and axle-pull guidance before installation; the Blplturb S10 listing states both requirements.

This Fizzvex kit suits buyers whose vehicle falls within its listed model applications and whose wheel bolt pattern matches one of the two stated options. Its emergency-brake calipers and supplied cables address parking-brake needs in the conversion.

5. SuDaoSun G-Body Kit

• Compatible with Vehicle Type: Car

Best for: Broad listed model coverage.

Why it ranks #5: Includes 11-inch drilled-and-slotted rotors, built-in-emergency-brake calipers, cables, hoses and mounting hardware for several listed GM models.

A listed application range covering Buick Skylark, Chevrolet G-Body models, Camaro, Firebird, and selected Olds and Pontiac years makes this SuDaoSun kit a broad-fitment option. Its two 11-inch drilled and slotted rotors pair with emergency-brake calipers, cables, rubber hoses, and mounting hardware for a bundled rear-disc conversion.

SuDaoSun specifies two 11-inch drilled and slotted rotors with 5-on-4.5-inch and 4.75-inch bolt patterns, giving buyers measurable details for checking their wheel setup. The calipers include built-in emergency brakes, and the package lists matching cables and rubber hoses. Complete mounting hardware, including brackets, bolts, and spacers, supports the conversion workflow. The broad vehicle list covers selected 1978–1988 Buick, Chevrolet, Pontiac, and Olds applications, but is not a substitute for checking the exact model year.

Skip it if you need stated wheel-size and axle-pull requirements in the listing; the SKAUTOPT G body and S10 kit provides those details.

Consider this SuDaoSun kit if your car is within the listed model years and you want rotors, emergency-brake calipers, hoses, and mounting hardware together. Its application list is broad, so exact vehicle-year fit remains the key boundary.

6. GELUOXI Drilled Rotor Kit

Best for: G-Body kit bundle seekers.

Why it ranks #6: Lists 11-inch drilled-and-slotted rotors, calipers with built-in emergency brakes, cables, hoses and hardware for G-body-related models.

This GELUOXI kit combines two 11-inch drilled and slotted rotors with calipers that have built-in emergency brakes, giving buyers a defined set of core rear-conversion parts. Its stated vehicle range includes selected Buick Skylark, Chevrolet, Olds, and Pontiac models, while the rotors list 5-on-4.5-inch and 4.75-inch bolt patterns.

The two stated rotor bolt patterns give buyers useful measurements to compare with their wheel setup, and the 11-inch drilled and slotted rotor specification identifies the included rotor style. Calipers with built-in emergency brakes are paired with two emergency-brake cables and rubber hoses. Complete mounting hardware is also listed, bringing installation components into the package. The applications span selected Skylark, Camaro, El Camino, Malibu, Monte Carlo, Firebird, Le Mans, Tempest, and Olds years, so exact model-year matching matters.

Skip it if you need stated wheel-size and axle-removal requirements before installation; Blplturb's S10 kit provides both details.

Consider GELUOXI if your vehicle matches its listed applications and you want drilled and slotted rotors with emergency-brake hardware in one package. Check the precise year and rotor bolt pattern, since the listing gives no installation thresholds.

7. Woosphy Drilled Rotor Kit

• Compatible with Vehicle Type: Cars

Why it ranks #7: Names replacement references and several related GM models, with 11-inch drilled-and-slotted rotors and calipers with built-in emergency brakes.

8. NEWZQ Drilled Rotor Kit

• Compatible with Vehicle Type: Car

Best for: OE-reference comparison buyers.

Why it ranks #8: Lists 11-inch drilled-and-slotted rotors and emergency-brake calipers for multiple related models, but offers no specific wheel or axle requirement here.

NEWZQ lists replacement references 916645641 and DBK7892LX, giving parts-comparison shoppers identifiers alongside a wide selection of stated Buick, Chevrolet, Olds, and Pontiac applications. Its package includes two 11-inch drilled and slotted rotors, calipers with built-in emergency brakes, emergency-brake cables, rubber hoses, and mounting hardware for a rear-disc conversion.

#9

9. Blplturb 10-Bolt Kit

• Compatible with Vehicle Type: Cars

Best for: 15-inch-wheel conversion planners.

Why it ranks #9: Provides drilled-and-slotted rotors and states 15-inch-or-larger wheels and axle removal are required, but its model identification is S10.

Blplturb clearly calls for disc-brake wheels at least 15 inches across and axle removal during installation, helping buyers assess two major fit and workflow constraints upfront. Its listed package adds two 11-inch drilled and slotted rotors, emergency-brake calipers and cables, rubber hoses, and mounting hardware for multiple stated Buick, Chevrolet, Pontiac, and Olds applications.

The explicit axle-pull instruction helps buyers plan the installation sequence and required access, while the 15-inch wheel minimum gives a direct preliminary fit check. The two 11-inch drilled and slotted rotors have 5-on-4.5-inch and 4.75-inch bolt patterns. Calipers with built-in emergency brakes, two cables, rubber hoses, and complete mounting hardware are listed. The application range covers selected Skylark, Camaro, El Camino, Malibu, Monte Carlo, Firebird, Le Mans, Tempest, and Olds years.

Skip it if you cannot pull the axles or have wheels under 15 inches; the JEGS 555-631475 listing does not state those requirements.

Pick Blplturb if your vehicle appears in its listed applications, has at least 15-inch wheels, and can be serviced with the axles pulled. The rotor bolt patterns and exact model-year range remain important fit checks.

#10

10. SuDaoSun Monte Carlo Kit

• Compatible with Vehicle Type: Cars

Best for: Monte Carlo application shoppers.

Why it ranks #10: Lists multiple related GM applications and the usual drilled-rotor components, but its model identifier is broad and the title targets Monte Carlo.

Monte Carlo 1978–1987 appears directly in this SuDaoSun kit's stated application list, alongside other selected Buick, Chevrolet, Pontiac, and Olds models. The package pairs two 11-inch drilled and slotted rotors with emergency-brake calipers, cables, rubber hoses, and complete mounting hardware, while clearly stating a 15-inch wheel minimum and axle-pull installation.

The explicit 15-inch-or-larger wheel requirement and axle-pull note give buyers two practical planning checks before undertaking the conversion. Two 11-inch drilled and slotted rotors use 5-on-4.5-inch and 4.75-inch bolt patterns, providing additional details for comparing the wheel setup. Calipers with built-in emergency brakes come with cables, rubber hoses, and complete mounting hardware. The application list includes Monte Carlo 1978–1987, but buyers should still match their precise vehicle and installation conditions.

Skip it if you cannot pull the axles or have wheels smaller than 15 inches; Fizzvex's G Body S10 listing does not state those requirements.

This SuDaoSun option suits Monte Carlo owners whose vehicle matches the listed 1978–1987 range and whose wheels meet the stated minimum. Plan for axle removal, and compare the rotor bolt patterns before committing to the conversion.
