If you are replacing the clutch, VW states you must replace (not reuse) all the bolts. Replacing the seals at the same time prevents leaks which cause an oil ruined disc. The kit includes the pressure plate to flywheel bolts, flywheel to crankshft bolts, and a transmission main shaft seal. This kit does not include the rear main engine seal. Why risk failure of a $900 clutch job over $40.
Along with the VW clutch installation kit, a new throw-out bearing is needed when you are installing a new clutch. While working on your transmission, we recommend replacing your gear oil. This synthetic gear oil will help reduce internal wear and improve the transmissions feel.
