Rings (not included).Sold as a set of 8.  Notes: Spacer ring included.KB Performance hypereutectic pistons are made from 390 aluminum alloy and heat-treated to T6 standards, which makes them 30 percent stronger than ordinary untreated hypereutectics. Their 100 percent CNC-machined crowns, high upper compression-ring location, gas-accumulator groove, drilled oil returns, and spiral-lock retainer grooves make these pistons outstanding for performance applications. They have a lightweight, rigid-rib skirt design that stabilizes the piston in the bore. All of this adds up to pistons that fit tighter than forged types, provide improved oil control, reduce blow-by, increase ring life, eliminate cold start-up knocking, and won't cost you an arm and a leg! Thousands of models are available, find the set and options designed for your vehicle and engine application.\u003c\/p\u003e","brand":"Pro Parts NZ","offers":[{"title":"Default Title","offer_id":46014164369581,"sku":"KBPKB122.030","price":834.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0763\/4819\/4989\/files\/KBPKB122.jpg?v=1778850532","url":"https:\/\/proparts.co.nz\/products\/pistons-chev-383-hyp-f-top-6-0-rod-4-030","provider":"Pro Parts NZ","version":"1.0","type":"link"}
