PISTON KIT HARLEY 3.882" SET/2, WOSSNER K8857D040-2 DAVIDSON, ROAD

Wossner Harley-Davidson Twin Cam Big Bore Piston Kit

Upgrade your Harley-Davidson Twin Cam 88 inch engine with this high-performance Wossner Piston Kit, specifically designed for a Big Bore 103 cubic inch configuration. This kit features a 3.882 inch bore with a +0.015 inch oversize for increased displacement and a domed 10:1 compression ratio to enhance power output.

Crafted in Germany, these forged pistons are engineered for superior structural integrity and exceptional heat dissipation. The advanced skirt coating technology minimizes friction and wear, while the elliptical design ensures a uniform bearing surface even under extreme thermal expansion. This precise engineering helps to prevent localized pressure buildup and evenly distributes thrust loads, ultimately preventing piston collapse under demanding engine conditions.

This comprehensive kit includes everything needed for installation: two forged pistons with skirt coating, high-quality rings, durable clips, and precision pins.
