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

Description

The forged performance piston kit for Harley Davidson Dyna models from 1999 to 2006 is made from a high-quality 4032 aluminum silicon alloy, which is known for its low extent and high strength. This material enables precise control of the heat extension and offers improved durability and performance. The pistons are provided with a special coating that minimizes the friction and extended the service life.

In addition, the pistons are equipped with accumulators, which ensures an optimized sealing of the rings. The upper areas of the pistons have mini -mills that help reduce detonation. These features together significantly improve the efficiency and performance of the engine.
