Manufacturer part number 653M04200. This kit is forged from high-silicon aluminum alloy for strength and dependability and is intended for trail and racing applications.\u003c\/p\u003e\u003cp\u003eThe piston design is engineered to support increased horsepower and torque, with high compression ratios and an ultra-stiff forged construction. The piston crown, ring grooves, and pin bore are E-Coated for wear resistance and protection from micro-welding, galling, and detonation. GP Series construction generally uses less machining on the outside to help seal the bore for increased compression, while boost ports are removed for a more predictable powerband and increased pull on the top end.\u003c\/p\u003e\u003cp\u003eThe kit features a forged piston, rings, wrist pin, and circlips. Cylinder sleeves must be purchased separately. Racer's Choice pistons are intended for expert racers and tuners only and may allow increased service intervals compared with conventional WISECO pistons. Distributor part number: 653M04200.
