Harley Davidson Dyna [1999-2006]-forged performance piston kit hub 4,000 "

Description

The piston kit for Harley Davidson Dyna models from 1999 to 2006 is made from a high-quality 4032 aluminum silicon alloy, which offers low extent and high strength. The construction was specially developed to minimize the weight and maximize the performance. A accumulator between the first and the second piston ring improves the sealing of the rings. Additional mini -plates on the top of the piston reduce the risk of detonations. The piston surfaces are also provided with an anti-friction coating in order to extend the lifespan and minimize friction.
