The design and engineering of a really good high performance clutch involves numerous challenges. For Bob Hays, the major one was the tendency of diaphragm-type clutches to “stick over center.” The answer turned out to be a special system of centrifugal-activated weights, which Hays went on to patent. Today, all but a small handful of Centerforce Clutch Kits include this centrifugal weighting system. There are a variety of clutch kits available for different driving situations. The Jeep Wrangler 1999 - 1999 Centerforce Clutch Kit is obviously designed for off-road adventures. It features a full-facing disc along with high-friction materials. IT is specially machined using a process that makes for better holding power and durability under the extreme conditions of off-road driving. With the Jeep Wrangler 1999 - 1999 Centerforce Clutch Kit, and annoying – and potentially hazardous – tendency to “stick over center” is eliminated. The Jeep Wrangler 1999 - 1999 Centerforce Clutch Kit will give you back the kind of control you need when driving in the middle of the wilderness.
