Wiseco VT2711 V-Twin Forged Piston Kit Bore Compression with Top End Gaskets - 3.885in 10.5 1

The Wiseco VT2711 is a high-performance forged piston kit designed for Twin Cam 88 engines bored to 1550cc (95 cubic inches), featuring a 3.885-inch bore diameter and a performance-oriented 10.5:1 compression ratio with a domed piston profile. Engineered, forged, and machined in the USA at Wiseco's facility in Mentor, OH, this kit delivers the strength and precision that serious V-Twin builders demand.

Each piston is forged from high-silicon aluminum alloy, providing superior tensile strength, reduced weight, and improved heat transfer compared to cast alternatives. Wiseco's Armor Plating treatment is applied to the piston crown, ring grooves, and pin bore — enhancing ring seal, preventing ring micro-welding, and protecting against heat and detonation damage for long-term reliability.
