Harley Davidson Dyna [2007-2017]-Forged performance piston kit hub 4.375 "...

Description

The piston kit was specially developed for Harley Davidson Dyna models from the construction years 2007 to 2017 and offers optimized performance through advanced technology. The pistons are made from a 4032 aluminum silicon alloy with low expansion, which ensures high strength and durability. The integrated accumulator improves the sealing of the rings, while the mini -milling in the upper part of the pistons minimize the risk of detonations. An anti-friction coating on the piston shirts reduces friction and contributes to the durability of the engine.

Content of the kit

• Two forged pistons
• Two sets of moly -coated rings made of ductile iron
• Piston bolts and safety clips
• Assembly oil to facilitate installation
