{"product_id":"dss-racing-fx-series-flat-top-piston-kit-4-000-bore","title":"DSS Racing FX-Series Flat Top Piston Kit 4.000\" Bore","description":"The DSS Racing FX-Series is a set of forged 4032 aluminum alloy piston and ring kits designed for a 4.7L\/289 engine displacement. These pistons feature a flat top with two valve reliefs and have a bore size of 4.000 inches (101.600mm). The kits include corresponding piston rings for installation.\n\nConstructed from premium aircraft-quality 4032 alloy, these pistons offer increased horsepower potential for naturally aspirated, nitrous, or boosted engines. They incorporate internal gussets for added strength and CNC milling in non-critical areas to reduce weight, balancing strength, power, and longevity. The patented X-Groove skirt design helps minimize damage from fuel wash down and break-in debris, promoting longer skirt, cylinder, and ring life. For stroker engines, this advanced skirt design enhances piston stability and ring seal for quieter operation.","brand":"DSS Racing","offers":[{"title":"Default Title","offer_id":53741274497336,"sku":"K135024000D","price":993.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/856707801.jpg?v=1793889685","url":"https:\/\/store.motormia.co\/products\/dss-racing-fx-series-flat-top-piston-kit-4-000-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
