WK1607 1200cc Pan/Shovel piston kit. +.020"

Designed for 1948 to 1979 1200cc Panhead and Shovelhead models, this Wiseco forged piston kit is .020 inches over standard. These pistons provide a 9:1 compression ratio, which is a slight bump over the factory 8.5:1, offering improved combustion efficiency. Forged construction ensures these pistons are strong enough for modern riding conditions. This set is sold as a pair and comes complete with Hastings rings, wrist pins, and circlips. The ring grooves are designed for 1.6mm top and middle rings and a 4.75mm oil ring. It is a premium choice for anyone looking to restore or upgrade the heart of their vintage Big Twin.
