Classic GMC/Chevrolet pickups, vans, and SUVs are some of the most venerable workhorses ever built. Millions of these sturdy rigs were manufactured between 1962-1995, and many still remain in service. These older trucks have always been great platforms for both business and pleasure. With the limitless possibilities for upgrading stout GM powerplants, their stock clutches (probably tired already) quickly run out of talent. Centerforce now has a premium street/track/trail solution in kit form: The Centerforce Dual Friction System (P/N KDF240916). The Centerforce Dual Friction clutch kit comes with all the components required to improve clamping power in older Chevys/GMCs. In addition to installation instructions, the box includes a pressure plate, a Dual Friction clutch disc, a new throwout bearing, a new pilot bearing, pressure plate bolts, and a clutch alignment tool. The Dual Friction clutch disc is the heart of the system. It features different friction surfaces on either side of the disc. A full-face friction surface on the pressure plate side – coupled with the disc’s sprung hub – provides easy engagement, light pedal effort, quiet operation, and longevity. On the flywheel side, a segmented, puck-style facing maximizes the clamping pressure to increase the clutch’s holding capacity. The end result is significantly increased gripping force that is suitable for the track or trail – but with light pedal and smooth operation to make it daily-drivable on the street. The Dual Friction system also utilizes Centerforce’s patented technologies. First and foremost are the famous Centerforce counterweights, which increase pressure plate clamp load with RPM. The patented ball-bearing pressure plate system further increases gripping power while keeping pedal effort low. This new Centerforce Dual Friction kit for classic Chevys/GMCs features a 12-inch OD pressure plate and 1-1/8-inch/10-spline disc. It fits many Chevy/GMC six- and eight-cylinder applications in 1962-95 pickups, vans, and SUVs. The pressure plate and clutch disc are also available individually. Centerforce also offers stock-replacement and mid-performance pressure plates and clutch discs for these older vehicles. The Centerforce I line is engineered with high-quality materials to be an OE replacement; the Centerforce II series uses upgraded full-face clutch disc materials for modified street-vehicle performance and for towing.
