Please note that we have these clutches in stock made by Centerforce. However, they differ from anything offered before:

A problem with all rebuilt clutches before we started selling these was reusing the factory twin discs. When the discs wear, the damper spring's sheet metal cage located in the disc hub is frequently fatigued by striking the flywheel bolts. To solve this problem, we use brand new factory clutch discs in our clutches from the begining. These clutch discs are disassembled, lined with high performance liner, and the pressure plate spring pressure is increased. All friction surfaces are milled and reassembled.
