GM LS Dish Top Our brand new Asymmetrical FSR (Forged Side Relief) forging design allows for the use of the most popular stroke and rod combinations while eliminating reluctor wheel clearance problems. Asymmetrical forging design maintains a larger skirt 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 significantly reduces friction in your engine. Lightweight and extremely durable, these pistons are machined for 1.2mm, 1.5mm, 3.0mm rings. Includes: .927 x 2.250 straight wall carbon steel wrist pin Wire locks Specifications : Part #: J312041 Bore: 4.010" Oversize: 010 LS2 Stroke: 4.000 Rod Length: 6.125" Compression Height: 1.115" Compression Ratio with 64cc chamber volume: 9.3 Compression Ratio with 68cc chamber volume: 9.0 Compression Ratio with 70cc chamber volume: 8.8 Dome Volume: -26.6cc Gram Weight: Footnote: Forged Side Relief / Forced Induction Reconmended Ring Set: JG3108-4000-7
