About This Product
For Evolution Big Twin engines requiring a .040" bore, this Wiseco high-compression piston kit provides the durability and performance needed for a serious build. Designed for 1984 to 1999 models, these forged aluminum pistons feature a domed profile that bumps compression to 10:1. This setup is compatible with OEM heads and provides a noticeable increase in torque and horsepower. The kit is sold as a set and includes everything you need: forged pistons, wrist pins, circlips, and Hastings rings. The ringlands are sized at 1.6mm for the top and middle rings and 4.0mm for the oil ring, ensuring a precision fit and excellent oil control in your rebuilt V-twin.
Manufacturer part number: WK1669.
