Rear Disc Conversion 78-88 GM 10 Bolt

The RIGHT STUFF DETAILING Rear Disc Conversion 78-88 GM 10 Bolt is a complete brake system retrofit kit engineered to upgrade the stopping performance of 1978–1988 General Motors vehicles equipped with 10-bolt rear axles. This conversion kit replaces legacy drum brake architecture with modern disc brake technology, delivering superior heat dissipation, consistent pedal response, and fade resistance—critical advantages for both street driving and high-demand applications where thermal management separates competent braking from marginal safety margins.

The kit includes a single-piston caliper design paired with an 11.000-inch plain rotor featuring an offset hat geometry. This combination provides adequate clamping force for light-to-moderate duty use while maintaining straightforward installation geometry on the GM 10-bolt platform. The iron rotor construction and natural (uncoated) finish deliver durable fade resistance and cost-effective corrosion management through proper maintenance. The offset hat design optimizes rotor ventilation and reduces unsprung weight compared to fully vented alternatives, balancing thermal performance with chassis dynamics.

This conversion serves owners of classic and early-model GM trucks and performance vehicles seeking to upgrade braking capability without extensive frame or suspension modification. Whether integrating into a restoration project, improving stopping power for modern traffic conditions, or preparing a vehicle for amateur track days, the GM 10-bolt rear disc conversion is a bolt-on solution that addresses the fundamental limitation of original drum brake systems. Installation requires rear axle removal and familiarity with brake hydraulics; professional installation is recommended for users unfamiliar with rear brake work.

Disc brake conversions for first-generation GM 10-bolt platforms have become a market standard among restoration shops and performance builders. This RIGHT STUFF DETAILING offering represents a proven approach to modernizing rear brake systems on vehicles manufactured between model years 1978 and 1988, providing a direct compatibility solution without requiring adapter plates or custom fabrication.
