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

Description

The piston kit was specially developed for Harley Davidson Dyna models from 1999 to 2006 and, thanks to its advanced construction, offers improved performance and reliability. The pistons are made from a 4032 aluminum alloy with low expansion coefficients and 11% silicon, which ensures high strength and durability. Special accumulator between the first and second piston ring optimizes the sealing and improves the engine output. Additional mini -plates at the top of the pistons help to reduce the tendency to detonate. The piston surfaces are also provided with an anti-friction coating in order to extend the lifespan and increase efficiency.
