Conrods, Flat top, with two valve reliefs, Compression Height 1.130 in., Piston Head Volume +7.00cc, Press-fit or floating 0.927in. Pin, Uses 1\/16 in. x 1\/16 in. x 3\/16 in. 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"},{"product_id":"pistons-chev-350-hyp-f-top-5-7rod-sealed-power-030","title":"PISTONS CHEV 350 HYP F\/TOP 5.7rod SEALED POWER 030","description":"\u003cp\u003eSpeed-Pro Digital Diamond Profile (DDP) hypereutectic pistons feature a new digital actuated diamond turning process that produces precision skirt profiles. This new technology creates a unique barrel profile of the pistons, promoting an oil wedge between the piston skirt and the cylinder wall. They have a newly designed ring groove geometry using Thermal Arching Compensation (TAC) that machines the piston ring grooves with an uptilt to offset thermal arching distortion. This squares the ring face up to the cylinder wall for increased power and decreased oil consumption. The also have the next generation of Duroshield skirt coating, reducing friction across the entire rpm range and increasing wear resistance for longer life and superior noise and vibration reduction. They also use precision-machined piston pin bores that allow for either fixed or floating wrist pins. The pistons come weight-matched to a 4 gram (+\/-2 grams) maximum variation within every engine set.\u003c\/p\u003e","brand":"Pro Parts NZ","offers":[{"title":"Default Title","offer_id":46014302617773,"sku":"SEAH345DCP30","price":260.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0763\/4819\/4989\/files\/SEAH345DCP30.jpg?v=1778852518"}],"url":"https:\/\/proparts.co.nz\/collections\/enginepart-pistons.oembed","provider":"Pro Parts NZ","version":"1.0","type":"link"}
