The piston kit for Harley Davidson Dyna [1999-2006] is made from an aluminum alloy with high silicon content, which is known for its excellent properties in terms of wear resistance and heat discharge. The construction of these pistons ensures a reduced noise level during operation by minimal distances between the piston and cylinder wall. Due to the precise production, including CNC freight grooves to avoid detonations, this piston kit is one of the most technologically mature of its kind.
The kit contains two pistons, suitable rings, piston bolts and safety rings. Depending on the kit, specific seals are included for the cylinder head and the cylinder base or complete sealing rates for the top end of the engine. All parts are manufactured in the USA and designed for durability and performance.
