KB931C060 Performance, 1200cc B.T. forged piston kit. +.060"

This KB Performance forged piston kit is built for 1941–1978 1200cc and 80-inch Knucklehead, Panhead, and Shovelhead engines. These +.060" oversize pistons are a great choice for older cylinders that need a significant bore to clean up. Forged from 4032 alloy with 11% silicone, these pistons offer the structural integrity required for heavy-duty use while allowing for a bit of flex to prevent cracking. They feature a domed head for an 8.5:1 compression ratio with standard 112cc heads. Sold as a set, they come with rings and offset wrist pins. Proper installation is key, as the offset pins require specific front-to-rear orientation as detailed in the provided instructions.
