About This Product
For 1999 to 2006 88 inch Twin Cam owners, this KB Performance forged piston kit provides a +.030 inch oversize for a 95 inch big bore conversion. These pistons deliver a 9.25:1 compression ratio with 85cc heads and are forged from 4032 alloy for maximum durability and resistance to cracking. The high-silicon content allows the piston to maintain its shape while providing the necessary flex under high-load conditions. Sold as a set, the kit includes offset wrist pins, retaining rings, and piston rings. It is vital to install these pistons in the correct front and rear orientation due to the offset pins. We recommend a piston-to-wall clearance that is .001 inch wider than standard cast specifications to ensure reliable operation and to prevent scuffing during thermal expansion.
Manufacturer part number: KB904C030.
