Hands down, the best forged piston for your high performance LS engine! Our Asymmetrical FSR (Forged Side Relief) forging is engineered for today’s high power normally aspirated and forced induction LS engines. The exclusive asymmetrical skirt maintains a larger skirt area on the heavily stressed major thrust side, while reducing friction with a smaller skirt on the minor thrust side. The result is a high strength, lightweight piston that outperforms the competition! Note: For applications over 800hp, a thicker wall wrist pin is recommended.Features:Pin #927-2250-15-51C (106g) for use with 6.125 Rod LengthRound Wire Locks # 927-073-MWIncludes:Accumulator GroovesDouble Pin OilersOffset Wrist PinPiston Specification:Make: CHEVROLETEngine: CHEVROLET LS GEN III/IVBore Diameter: 4.005Compression Height: 1.304Compression Ratio with 64cc chamber volume: 10.6Compression Ratio with 68cc chamber volume: 10.1Compression Ratio with 70cc chamber volume: 9.9Piston Volume: -5Cylinder Head: LS 12 DEG/15 DEG COMBO VRPiston Pin Outside Diameter: 0.927Piston Pin Length: 2.250Piston Pin Material: 5115Ringset Included :NoTop Compression Ring Thickness: 0.048Second Compression Ring Thickness: 0.06Oil Ring Thickness: 0.1175Piston Material: 2618Forging Type: FSRPiston Avg Weight: 407Pin Wall Thickness: 0.150Piston Type: Flat
