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 was specially developed to improve the performance and reliability of the engine. The pistons are made from a 4032 aluminum silicon alloy, which is known for its low extent and high strength. Special accumulators improve the sealing of the rings and contributes to reducing the incineration of combustion, supported by mini -milling on the top of the piston.

The piston surfaces are provided with an anti-friction coating that minimizes friction and extends the lifespan. The kit is sold as a couple and includes all the necessary components for installation, including moly -coated rings, piston bolts and assembly oil.
