Designed for serious performance builds and high-revving engines, this Super Damper & Bolt Kit helps eliminate crankshaft vibration in Austin Healey 6-cylinder models (BN4 to BJ8). The damper protects against crankshaft fatigue, offering smoother and more reliable engine performance—particularly in tuned or race applications.
This kit is designed for use with our Modified Front Yoke – IBP167ASD, which provides the necessary clearance for the larger damper and pulley. It also requires our specially made Pulley – ENG644P to complete the setup.
This is a vital performance upgrade for owners looking to improve engine durability and smoothness under spirited or extended driving conditions.
