Product Details
Spool Performance proudly presents their Stage 2 Transmission Kits for the 8HP45, 8HP50, and 8HP51 series transmissions. Designed to exceed the limitations of stock components, these kits offer an extraordinary torque capacity of over 1000 ft-lbs. This impressive upgrade showcases 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.
Advanced Hub Design
The C and E clutch hubs in the 8HP series are critical points of failure due to their OEM construction from flimsy, cast A380 aluminum. These components are infamously prone to shearing or breaking of the lock splines, and the steel clutch plates can dig into the splines, causing hang-ups and burnouts.
Key Upgrades:
- Material: Re-engineered using 7075 series aluminum, one of the strongest grades of billet aluminum.
- Treatment: Heat-treated and hard-anodized to improve strength and surface hardness, delivering superior resistance to shear forces and wear from steel disc engagement.
- Design Enhancements: Improved clutch cooling paths, oil evacuation, and increased clutch pack area for optimized performance.
Superior Friction Materials
Our FX-RT frictions, developed in-house, offer significantly higher friction coefficients than OEM materials. These frictions boost performance and durability without compromising engagement and overall drivability. This development is the product of over a year of rigorous testing and refinement across various platforms.
Ease of Installation
We recognize that rebuilding a transmission can be intimidating, which is why we've specifically designed our kits for easiest 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 additional steel plates for builders who prefer custom clearance settings.
