{"product_id":"forged-flat-top-piston-set-4-040-bore-5-0cc-dish","title":"Forged Flat-Top Piston Set, 4.040\" Bore, -5.0cc Dish","description":"The Mahle MAH-930200640 is a complete drop-in forged piston assembly engineered for Small Block Chevy (SBC) engines. Designed with performance in mind, these pistons are forged from 4032 low-expansion aluminum alloy, which allows for tighter cylinder-to-wall clearances and improved temperature stability. The anti-friction skirt coating reduces drag, while forced pin oiling enhances wrist pin lubrication.\n\nThis PowerPak piston set features a flat-top design with a -5.0cc volume, achieving an 11.2:1 compression ratio when paired with 64cc cylinder heads. The pistons have a 4.040-inch bore, a 3.750-inch crankshaft stroke, and a 6.000-inch rod length, with a compression height of 1.125 inches. The pin bores are CNC precision-machined for accuracy.","brand":"Mahle","offers":[{"title":"Default Title","offer_id":52662887579960,"sku":"MAH-930200640","price":776.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687501734.jpg?v=1784321764","url":"https:\/\/store.motormia.co\/products\/forged-flat-top-piston-set-4-040-bore-5-0cc-dish","provider":"MOTORMIA","version":"1.0","type":"link"}
