KB PERFORMANCE Piston Kit - XL KB295.010

If you're building a high-revving engine or pushing boost levels beyond stock capability, piston durability and ring seal directly impact power output and engine longevity. KB Performance pistons are held to tolerances tighter than most OEM specifications, allowing you to run closer clearances for reduced piston rock and superior ring seal—critical advantages whether you're competing on the track or maximizing horsepower in the shop. With T-5 heat-treated 390 hypereutectic aluminum and diamond-machined geometry, these pistons deliver the precision fit and thermal stability demanded by serious engine builders.
