Description
The Superior BBCO (Big Block Change Over) clutch kit addresses the specific fitment requirements of Ford 429/460 and 351M/400 engines running the 11.5" long bolt pattern. Whether you're upgrading from a worn factory clutch or building a fresh big block combination, this kit delivers the heat resistance and holding power that aggressive street driving and open track sessions demand.
Kevlar friction material on both faces of the disk sets this kit apart from standard organic offerings. Where organic facings fade under repeated high-heat cycles, Kevlar maintains consistent grip and pedal feel - critical when you're pushing hard lap after lap or making repeated passes. The 600 ft-lb torque rating provides headroom for modified engines while the sprung hub absorbs driveline shock, protecting your transmission's synchronizers and delivering smooth, progressive engagement.
The 11.5" long pattern diaphragm pressure plate uses 5/16"-18 mounting hardware and provides modern clamping force with lighter pedal effort than traditional long-style covers. Every Superior clutch disk is hand-assembled in MDL's facility, where technicians verify tolerances and balance before shipping. The included big block Ford pilot bushing and alignment tool ensure precise installation.
This kit fits Ford big block applications (429/460) and 351M/400 engines with the 11.5" long clutch bolt pattern. Requires 10-spline x 1-3/8" input shaft. Does not include throwout bearing - select the appropriate bearing for your bellhousing and release system. Made in the USA and backed by MDL's 1-year warranty and lifetime technical support.
