This solid flywheel replaces the OE dual mass flywheel This kit contains: solid flywheel, pressure plate, clutch disc, throw-out bearing, pilot bearing, alignment tool and flywheel mounting bolts. Dual-mass flywheels (DMF) help contribute to a smooth driving experience for cars with manual transmissions. Unlike solid flywheels, dual-mass flywheels cannot be resurfaced during an aftermarket clutch installation, escalating the total cost associated with clutch replacement. The SACHS line of solid flywheel conversion kits is a low cost, high quality alternative for customers needing to replace the dual-mass flywheel clutch system.
