{"product_id":"dss-racing-fx-series-piston-set-4-075-in-bore","title":"DSS Racing FX-Series Piston Set, 4.075 in. Bore","description":"The DSS Racing D.S.S. FX-Series pistons are forged from premium aircraft quality 2618 alloy, designed to increase horsepower potential while withstanding high power demands. These pistons feature horizontal gas porting and internal gussets for added strength, making them suitable for naturally aspirated, nitrous, or boosted engines. Additional CNC milling optimizes weight for a balance of strength, power, and longevity. The patented X-Groove skirt design enhances skirt, cylinder, and ring life by reducing damage from fuel wash down and debris. For stroker engines, the advanced skirt design improves stability and ring seal for quieter operation. This set includes XR Extreme duty wrist pins and features forced pin oiling, drilled bottom land oil drain backs, pin lock ring removal slots, and precision-honed pin bores. The pistons have a 4.075 in. bore, a stock stroke type, and a 6.2L\/378 actual engine displacement, with dish-style heads featuring two valve reliefs and a +12.00cc volume. Piston rings are sold separately.","brand":"DSS Racing","offers":[{"title":"Default Title","offer_id":53741059440952,"sku":"3-2744-4075","price":994.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/856693112.jpg?v=1793888531","url":"https:\/\/store.motormia.co\/products\/dss-racing-fx-series-piston-set-4-075-in-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
