Give your 1988–1998 Chevrolet or GMC OBS truck the braking upgrade it deserves with this complete rear disc brake conversion kit. Designed for GM’s iconic “Old Body Style” pickups, this kit replaces factory drum brakes with high-performance disc brakes that deliver shorter stopping distances, improved heat dissipation, and a more responsive pedal feel. This rear brake upgrade provides the confidence and safety you need in today’s driving conditions, while keeping the rugged style of your classic GM truck intact.
Built for long-lasting performance, the kit features black-coated drilled and slotted rotors in the correct 5x5 bolt pattern for superior cooling, fade resistance, and corrosion protection. Heavy-duty black powder-coated caliper brackets and black powder-coated calipers ensure years of reliable service, while stainless steel brake hoses improve pedal firmness and resist deterioration better than traditional rubber lines. Grade 8 hardware guarantees a secure, professional-quality installation.
Whether your OBS truck is stock height, lowered, or part of a high-performance build, this kit is engineered for straightforward, bolt-on installation—no major modifications required. Ideal for restorations, custom builds, lifted trucks, or high-horsepower street machines, this OBS rear disc conversion gives your 1988-1998 GM truck modern braking power without losing its classic feel.
