About the Spool Performance 8HP Stage 2 Transmission Kit

After more than a year of rigorous development and testing, Spool Performance proudly presents the Stage 2 Transmission Kit designed for the ZF 8HP 70, 8HP75, and 8HP76 transmissions. Built to exceed stock limitations, this upgrade delivers over 1200 ft-lbs of torque capacity—a significant enhancement in strength and durability.

This comprehensive kit includes:

• Advanced friction materials developed in-house for superior engagement and longevity

• Custom billet 7075 aluminum C and E hubs, heat-treated and hard-anodized for exceptional strength

• Redesigned pressure plates and apply plates

• Increased clutch counts in every clutch pack for improved torque handling

Why Upgrade?

Advanced Hub Design:
OEM C and E clutch hubs are known weak points, made from fragile cast A380 aluminum that is prone to shearing or spline failure due to steel clutch plate wear. Our billet 7075 hubs are heat-treated and anodized to resist shear forces and wear, with improved oil flow and cooling paths to optimize performance.

Superior Friction Materials:
Our FX-RT friction materials deliver much higher friction coefficients than stock, ensuring enhanced durability without sacrificing smooth engagement or drivability.
