These high-performance piston kits have been re-designed with stock ring lands, and are forged from high-silicone aluminum alloy that provides excellent wear and heat dissipation characteristics. The unique shape permits tight piston-to-wall clearances for quieter operation. When combined with the ring package and CNC-machined anti-detonation grooves, it becomes one of the most technically-advanced pistons available. Sold in sets, complete with two pistons, rings, wrist pins and circlips. Some kits also include special head and base gaskets or complete top-end kits where indicated.
