Built from strong 2618 aluminum, these pistons are engineered to sustain the demands of forced induction and high RPM racing builds.\u003c\/p\u003e\u003cp\u003eWith a -9.0 cc dished crown, the compression ratio is optimized (~8.5-8.9:1) to safely handle boost while maintaining good efficiency and detonation resistance. The ArmorGlide® skirt coating reduces friction, and the strutted forging design enhances structural rigidity under high loads.\u003c\/p\u003e\u003cp\u003eThis comprehensive kit includes six pistons, 22 mm wrist pins, circlips, and a high-quality 8750XX ring set. The forced-pin oiling ensures reliable lubrication at the wrist pin area, making this kit ideal for serious performance tuners and race builders using the iconic VG30DETT powerplant.\u003c\/p\u003e","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":53325024133439,"sku":"WISK549M875AP","price":998.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/531413624dd53a5d2a8601f73c14383eL.jpg?v=1780025343","url":"https:\/\/wcaperformance.com\/products\/wiseco-nissan-vg30-turbo-9cc-1-260-x-87-5-piston-shelf-stock-kit","provider":"WCA Performance","version":"1.0","type":"link"}
