KB931C050 Performance, 1200cc B.T. forged piston kit. +.050"

Keep your vintage iron running strong with this KB Performance forged piston kit, designed for 1941–1978 1200cc and 80-inch Knucklehead, Panhead, and Shovelhead models. These are +.050" oversize pistons that serve as a rugged replacement for stock components. Forged from 4032 aluminum alloy, they provide exceptional strength and resistance to detonation. The domed head is designed to achieve an 8.5:1 compression ratio with a 112cc head. Sold as a set, the kit includes rings, wrist pins, and retaining rings. These pistons use offset wrist pins to reduce noise and wear, so it is essential to follow the installation instructions to ensure they are oriented correctly for the front and rear cylinders.
