About This Product
This Wiseco forged piston kit is a high-quality replacement for 1984 to 1999 1340cc Evolution Big Twin engines. Bored to .010 over stock, these forged pistons offer superior strength and durability compared to cast alternatives. The kit maintains a stock 8.5:1 compression ratio, making it an excellent choice for a reliable top-end rebuild. However, if you are running Screamin' Eagle cylinder heads, these pistons will bump your compression up to a peppier 9.5:1. Each kit comes complete with premium Hastings rings, circlips, and wrist pins, providing everything a mechanic needs to refresh an Evo motor and get it back on the road with confidence.
Manufacturer part number: WK1641.
