Rear Disc Conv. Kit GM 10/12 Bolt Stag Shock

The Rear Disc Conv. Kit GM 10/12 Bolt Stag Shock from Right Stuff Detailing is a complete rear brake conversion system designed for General Motors 10-bolt and 12-bolt axle housings commonly found in full-size trucks, muscle cars, and performance vehicles from the 1960s through early 2000s. This kit addresses the critical need for upgraded stopping power on classic and modified vehicles where original drum brakes no longer provide adequate thermal capacity or modulation for contemporary driving demands or track use. Whether you're restoring a Chevelle, Camaro, or truck, this conversion bridges the gap between nostalgia and modern safety standards.

This conversion kit features an 11-inch plain rotor paired with a single-piston caliper architecture, delivering reliable hydraulic braking force with straightforward servicing and predictable pedal feel. The plain rotor design—free of vanes or cooling fins—offers weight savings and simplified machining, making it ideal for street applications where brake fade is less critical than cost and compatibility. The offset hat design ensures proper wheel clearance while maintaining robust structural integrity under hard braking. Iron construction provides excellent thermal conductivity and fade resistance, while the natural finish resists corrosion better than bare cast surfaces. The complete kit format means all necessary brackets, hardware, and components arrive ready for installation, eliminating sourcing delays and compatibility guesswork.

This system is ideal for restoration enthusiasts, performance builders, and anyone upgrading vintage GM rear-axle vehicles seeking OEM-style appearance with modern stopping capability. The kit's design accommodates both 10-bolt and 12-bolt differentials, making it compatible with a broad range of Chevrolet, GMC, and Pontiac platforms. Installation requires basic mechanical competency, professional brake bleeding, and proper torque specifications; many builders pair this with front disc conversions for balanced braking balance. At 67.5 lbs, the complete assembly is easily managed during installation and poses no suspension stress.
