An efficient crankshaft damper is essential for reliability on all A-Series engines, from mild road to full-race. This effectively dampens vibrations to improve longevity of the main bearings, and is more durable than the standard dampers, which can deteriote with age, perish and fall apart.
The centre boss is machined from lightweight aluminium, holes drilled for weight saving then anodised black. The damper ring is then machined from high grade steel and bonded to the central boss using natural rubber.
The damper ring will require an additional pulley to mount to the crankshaft, as seen in the related products below. We would recommend opting for the complete balanced kit, as it comes with everything you require, even the bolt and washer.
