{"product_id":"flat-top-hypereutectic-piston-set-4-030-inch-bore","title":"Flat Top Hypereutectic Piston Set, 4.030-inch Bore","description":"The Speed-Pro SEAH336CP30 is a set of eight hypereutectic pistons engineered for Small Block Ford applications.\n\nConstructed from an aluminum alloy with 16% silicon (FM244), these pistons offer enhanced strength and wear resistance. They feature a 4.030-inch bore, a flat top design with machined valve reliefs, and a -12.00 cc volume, contributing to a specific compression ratio. The pistons utilize 5\/64-inch top and second ring grooves and a 3\/16-inch oil ring groove. Sophisticated \"barrel\" profiles are incorporated to optimize the oil wedge between the skirt and the cylinder wall, while the piston skirts are protected by a DUROSHIELD coating for extended life and reduced friction.\n\nThese pistons are weight-matched to within +\/- 2 grams, ensuring balanced engine operation. The included wrist pins are of a floating\/press style with a 0.912-inch diameter, and LR-63 lock rings are provided for floated applications. The hypereutectic material and coated skirt contribute to their performance and longevity in demanding conditions.","brand":"Speed-Pro","offers":[{"title":"Default Title","offer_id":52663777755448,"sku":"SEAH336CP30","price":201.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687712992.jpg?v=1784329525","url":"https:\/\/store.motormia.co\/products\/flat-top-hypereutectic-piston-set-4-030-inch-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
