While the Mustang and Camaro really took the SEMA Show by storm this year, the new Chrysler muscle cars weren’t completely left out of the game, with plenty of new performance products being showcased. One of those that
garnered plenty of interest was the all-new twin disc clutch from Advanced Clutch Technology (ACT), designed for the 2009-10 Dodge Challenger. With double the friction surfaces to distribute the torque flow over the two discs, the powerful 5.7L and 6.1L HEMI V8 engines can greatly benefit from all of the advantages that this new clutch has to offer in the drivetrain department.
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.
