{"product_id":"dss-racing-fx-series-piston-set-4-000-bore-flat-top","title":"DSS Racing FX-Series Piston Set 4.000\" Bore Flat Top","description":"The DSS Racing FX-Series pistons are forged from 2618 alloy for increased horsepower potential and durability. These pistons are designed for naturally aspirated, nitrous, or boosted engines, featuring internal gussets for added strength. CNC milling in non-critical areas reduces weight, balancing strength, power, and longevity.\n\nThe FX-Series pistons include the patented X-Groove skirt design, which minimizes damage from fuel wash down and break-in debris, contributing to superior skirt, cylinder, and ring life. For stroker engines, the advanced skirt design enhances piston stability and ring seal for quieter operation.\n\nThis specific set is for a 4.000 in. bore with a +5.00cc piston head volume, designed for a 4.7L\/289 Small Block Ford engine with a stock stroke and a 5.155 in. rod length. They are flat-top pistons with three valve reliefs and are sold as a set of 8.","brand":"DSS Racing","offers":[{"title":"Default Title","offer_id":53742999404856,"sku":"2-3501-4000D","price":809.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/858350101.jpg?v=1793905005","url":"https:\/\/store.motormia.co\/products\/dss-racing-fx-series-piston-set-4-000-bore-flat-top","provider":"MOTORMIA","version":"1.0","type":"link"}
