Description
Sourcing a reliable clutch for vintage Aston Martin applications can be a frustrating exercise in hunting obsolete parts or settling for questionable aftermarket offerings. The Superior Series 9-inch clutch assembly solves that problem with a purpose-built disk engineered specifically for the 1-1/16-inch, 10-spline input shaft found in select Aston Martin drivetrains.
Every Superior clutch disk is hand-assembled at MDL's facility in Idaho, where critical tolerances--spline engagement, hub concentricity, and friction material adhesion--are double-checked before the assembly leaves the shop. The organic friction facings on both sides deliver the progressive engagement characteristics that make street driving enjoyable, without the grabbiness or chatter of aggressive racing compounds.
The diaphragm pressure plate maintains consistent clamping force throughout its service life, eliminating the hot spots and uneven wear that plague inferior designs. The sprung hub absorbs torsional shock from the engine and smooths power delivery through the drivetrain--critical for preserving gearbox synchros and providing refined pedal feel. At 200 lb-ft torque capacity, this assembly handles stock and moderately upgraded powerplants without slippage.
The kit arrives ready to install with everything you need: pressure plate, clutch disk, throw-out bearing, pilot bushing, and an alignment tool to ensure proper indexing during assembly. Backed by MDL's 1-year free-from-defect warranty and lifetime technical support. Made in the USA.
