After over a year of rigorous testing, Spool Performance proudly presents our Stage 2 Transmission Kits for the 8HP70, 8HP75, and 8HP76 series transmissions. Engineered to exceed the limitations of stock components, these kits deliver an exceptional torque capacity of over 1200 ft-lbs. This comprehensive upgrade includes advanced friction materials developed in-house, billet 7075 heat-treated and hard-anodized custom-designed C and E hubs, bespoke pressure plates, apply plates, and increased clutch counts for every clutch pack.
The C and E clutch hubs in the 8HP series are critical points of failure due to their OEM construction from weak, cast A380 aluminum. These components are prone to shearing or breaking of the lock splines, and the steel clutch plates can dig into the splines, causing hang-ups and burnouts.
Our FX-RT frictions, developed in-house, provide significantly higher friction coefficients than OEM materials. These frictions ensure performance and durability without compromising engagement and overall drivability. This development is the culmination of over a year of continuous testing and refinement across multiple platforms.
Rebuilding a transmission can be intimidating, so we’ve designed our kits for seamless installation. All clutch packs are pre-clearanced and ready to drop in with custom pressure and apply plates, eliminating guesswork for the installer. Additionally, the kit includes extra steel plates for builders who prefer custom clearance settings.
The Spool Performance Stage 2 Transmission Kit ensures your 8HP70, 8HP75, and 8HP76 series transmissions are ready to handle increased torque while maintaining reliability and drivability.
