• Kit Includes: 1 forged piston, 1 ring set, 1 wrist pin and 1 pair of wrist pin clips.
• Dedicated forgings used for superior strength to weight ratio utilizing aerospace alloy.
• Horizontal slot-pin oiling reduces friction and provides scuff resistance, along with a pressure seal groove for maximum ring seal.
• The skirt shape (barrel/cam) is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy.
• An optimally designed skirt shape provides stability which is important for proper ring seal and reduced friction.
