Highly boosted, direct injection engines, such as GM’s LNF 2.0, require strict adherence to the original dome and bowl design to maintain proper combustion characteristics. Wiseco’s new K635 series piston is the only forged piston utilizing special form tooling for the correct shape dome and bowl design. Coupled with our brush dome deburring, Nitride steel XX rings, ArmorGlide® skirt coating, and extra stout 5mm wall thickness pins, this is the only forged piston with the technology needed to properly compliment D.I. Find out more about this piston and our complete sport compact line at Wiseco.com or call our sales team at 800-321-1364. Wiseco’s GM 2.0 LSJ/ LFN piston kits (K635M86/ K635M865/ K635M88) retail at $721.56 and include rings, clips, and pins for your rebuild.
