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.\u003c\/p\u003e \u003cp\u003e \u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003ePin #927-2250-15-51C (106g) for use with 6.125 Rod Length\u003c\/li\u003e \u003cli\u003eRound Wire Locks # 927-073-MW\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e \u003c\/p\u003e \u003cul\u003e \u003cli\u003eAccumulator Grooves\u003c\/li\u003e \u003cli\u003eDouble Pin Oilers\u003c\/li\u003e \u003cli\u003eOffset Wrist Pin\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003e Piston Specification:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMake: CHEVROLET \u003c\/li\u003e \u003cli\u003eEngine: CHEVROLET LS GEN III\/IV\u003c\/li\u003e \u003cli\u003eBore Diameter: 4.000\u003c\/li\u003e \u003cli\u003e Compression Height: 1.115\u003c\/li\u003e \u003cli\u003eCompression Ratio with 64cc chamber volume: 9.3\u003c\/li\u003e \u003cli\u003eCompression Ratio with 68cc chamber volume: 9.0\u003c\/li\u003e \u003cli\u003eCompression Ratio with 70cc chamber volume: 8.8\u003c\/li\u003e \u003cli\u003ePiston Volume: -26.1\u003c\/li\u003e \u003cli\u003eCylinder Head: LS 12 DEG\/15 DEG COMBO VR\u003c\/li\u003e \u003cli\u003e Piston Pin Outside Diameter: 0.927\u003c\/li\u003e \u003cli\u003ePiston Pin Length: 2.250\u003c\/li\u003e \u003cli\u003ePiston Pin Material: 5115\u003c\/li\u003e \u003cli\u003e Ringset Included: No\u003c\/li\u003e \u003cli\u003e Top Compression Ring Thickness: 0.048\u003c\/li\u003e \u003cli\u003e Second Compression Ring Thickness: 0.06\u003c\/li\u003e \u003cli\u003eOil Ring Thickness: 0.149\u003c\/li\u003e \u003cli\u003ePiston Material: 2618\u003c\/li\u003e \u003cli\u003eForging Type: FSR\u003c\/li\u003e \u003cli\u003e Piston Avg Weight: 392\u003c\/li\u003e \u003cli\u003ePin Wall Thickness: 0.170 \u003c\/li\u003e \u003cli\u003ePiston Type: Dish \u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"JE","offers":[{"title":"Default Title","offer_id":50865009197303,"sku":"J312039","price":684.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/4599\/1415\/files\/J312039.jpg?v=1781586055","url":"https:\/\/trendlumo.com\/products\/je-ls2-asymmetrical-fsr-dish-top-forged-piston-2","provider":"trendlumo","version":"1.0","type":"link"}
