Description

Ford's big block Toploader transmissions--the heavy-duty units found behind 427, 428, and 429 engines in legendary muscle cars like the Mustang, Cobra, Fairlane, and Torino--demand clutch components that can handle serious torque without sacrificing streetability. The 1-3/8-inch diameter, 10-spline input shaft configuration was Ford's answer for high-horsepower applications, and this MDL Superior clutch set delivers the precise engineering these transmissions require.

The Kevlar/Kevlar disk facing combination provides the ideal balance between street manners and track capability. Unlike single-material disks that compromise either smoothness or holding power, the dual Kevlar construction delivers consistent friction characteristics across temperature ranges while maintaining the progressive engagement serious drivers expect. The sprung hub design absorbs driveline shock during aggressive shifts, preventing the harsh engagement that damages synchros and ring gears while delivering a more comfortable driving experience in stop-and-go traffic.

Every MDL Superior clutch disk is hand-built in-house, ensuring quality control that mass-produced units cannot match. Each disk undergoes precision balancing and tolerance verification before assembly, guaranteeing smooth operation and extended service life. The diaphragm pressure plate delivers consistent clamping force and reliable release characteristics, while the included hydraulic throwout bearing eliminates the adjustment headaches and pedal-effort issues associated with mechanical linkage systems.

Rated at 600 ft-lbs of torque, this clutch set handles modified big blocks and serious performance applications with confidence. Designed for performance street driving and open tracking events. Made in the USA and backed by MDL's 1-year defect-free warranty with lifetime technical support.
