Our Achilles Motorsports Race clutch & flywheel kit is made up of a custom SFI Certified Aluminum flywheel utilizing a 7.25" Tilton race clutch and hydraulic release bearing that is designed to eliminate the stock type fork arm, pivot balls and external slave cylinders. The constant contact design of the Tilton hydraulic release bearing maintains positive pedal feel even as the clutch wears. The hydraulic release bearing also self adjusts to wear.
