With an absolute gaggle of 2011 Mustang GT aftermarket performance parts being announced at SEMA, it would seem as though many would just get lost in the crowd. However, one of the more intriguing things hitting the market of late have been the twin disc clutches that distribute torque flow over twice the frictional surface that the dual discs provide – a stellar complement to the 400-plus horsepower 5.0L engine. And it would only seem natural that Advanced Clutch Technology (ACT), one of the leaders in clutch and drivetrain technology, would deliver with a trick piece of their own for the new Mustang.
ACT’s new Twin Disc assemblies have a multitude of key features. Among those are solid hub discs that are of minimal weight for faster shifts, resulting in less stress on synchronizers and proving race performance with street manageability, along with proprietary Positive Lift Floater System design for quiet operation with no floater rattle or posts to wear. The premium ceramic friction materials provide high heat tolerance with low wear rates, and the flywheel material is properly distributed for maximum strength, low inertia, good heat tolerance, and rigidity.
The diaphragms are induction hardened on the release bearing contact area to reduce wear and promote smooth operation, and stronger drive straps and rivets are used when needed to strengthen the pressure plate and prevent breakage.
The 26-spline clutches for the Challenger are available in nine different forms with three different levels of pressure plates among them, ranging from a rating of 850 ft-lbs up to 1,450. The kits are complete with a one-piece, forged chromoly flywheel.
