Description
The Superior Clutch Kit solves the need for reliable, high-performance power transfer in Ford applications requiring the 12-3/8" equal-spaced bolt pattern with mechanical actuation. Built for enthusiasts pushing performance street and open track builds, this clutch kit delivers the aggressive engagement characteristics that high-output engines demand while remaining streetable.
The 12-3/8" diaphragm pressure plate provides distinct advantages over coil spring designs: lighter pedal effort, smoother engagement, and consistent clamp load that doesn't diminish with disc wear. Diaphragm pressure plates maintain stable clamping force at high RPM, while coil springs can lose efficiency under centrifugal force. The result is a clutch that feels better in traffic and holds harder at the track.
The 11" clutch disc features Kevlar/Kevlar facings on both sides - engineered for aggressive bite, superior heat dissipation, and extended service life under demanding conditions. Kevlar's unique friction characteristics mean torque capacity actually increases as temperature rises during hard use, the opposite of organic compounds that fade with heat. The sprung hub design absorbs drivetrain shock during engagement, protecting your transmission and reducing chatter for smooth operation.
Every Superior clutch is hand-assembled in-house and double-checked for accuracy before shipping, ensuring you receive a ready-to-install premium piece right out of the box. This kit includes everything needed for installation in Ford applications with mechanical throwout bearing actuation, including a Small Block Ford pilot bushing. Perfect for muscle car restorations, street performance builds, and TREMEC transmission swaps. Made in the USA.
