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

Product description

This high-quality piston kit for Harley Davidson Dyna models from the years 1999 to 2006 is made from a 4032 aluminum silicon alloy, which convinces with its low extent and high strength. The forged pistons are specially designed in such a way that, despite their light weight, they offer high stability. Special accumulators between the first and second piston ring improves the sealing and efficiency of the engine.

The surface of the piston is treated with anti-friction coating, which minimizes friction and increases the durability. In addition, small grooves are attached to the top of the pistons, which help to reduce detonation. The kit contains two pistons, each with one set of high -quality, molybdenum -coated rings made of ductile iron, piston bolts, safety clips and assembly oil.
