About This Product
This KB Performance big bore piston set is the perfect choice for 1999 to 2006 Twin Cam A or B owners looking to increase displacement from 88" to 95". These +.030" oversize pistons require boring the stock cylinders to 3-7/8" and work seamlessly with stock heads to provide a 10.5:1 high-compression ratio. Sold as a set, they are produced from T6 heat-treated 390 hypereutectic cast aluminum. The high silicone content allows for tight clearances, which virtually eliminates piston noise and extends engine life. The dome-head design provides a significant performance boost. Please ensure the top compression ring is gapped with additional clearance as specified in the instructions to accommodate the heat generated by this high-compression setup.
Manufacturer part number: KB411030.
