Harley Davidson Fl Shovel [1978-1984]-forged performance piston kit Hub 4.250 "

Product description

This forged performance piston kit for Harley Davidson Fl Shovel models from 1978 to 1984 is made from a high-quality 4032 aluminum alloy with 11% silicon proportion. The use of this special alloy leads to a low extent and increased strength of the piston. A accumulator position positioned between the rings improves the seal, while fine mini -mills minimize the risk of detonations in the upper part of the piston. The piston surfaces are also provided with an anti-friction coating in order to reduce friction and extend the lifespan.
