{"product_id":"barra-titanium-retainer-set","title":"Barra Titanium Retainer Set","description":"The Atomic Barra Titanium Retainer Set is engineered to enhance high-RPM performance in Ford Barra DOHC 4.0L 6-cylinder engines by significantly reducing valvetrain mass. This reduction allows the engine to rev harder, faster, and more reliably, while simultaneously improving valve control during extreme boost and high RPM scenarios.\n\nPrecision CNC-machined from premium aerospace-grade titanium, these retainers offer an optimal balance of being ultra-lightweight yet incredibly strong. They are particularly beneficial for engines equipped with aftermarket camshafts, high-lift profiles, stiffer valve springs, or those aiming for substantial RPM targets. These retainers are a standard component in top-tier Atomic engine builds and are recommended for serious Barra engine enthusiasts.\n\nThe use of titanium retainers contributes to better valve tracking and reduced stress on valve springs at high RPM, enabling more stable operation at extended engine speeds. This upgrade helps prevent valve float and lifter instability, making it a perfect match for performance valve springs and camshafts. They provide a precision fit for both stock and Atomic performance valves.\n\nThis set includes 24 lightweight titanium valve spring retainers, providing full coverage for all six cylinders. They are recommended for use with Heavy Duty roller rockers and 1–2mm oversize valves and have been trusted in Atomic-built heads capable of producing 1000–1800+ horsepower.","brand":"Atomic","offers":[{"title":"Default Title","offer_id":52687004008760,"sku":"306851-T-24","price":372.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660677169.webp?v=1784879361","url":"https:\/\/store.motormia.co\/products\/barra-titanium-retainer-set","provider":"MOTORMIA","version":"1.0","type":"link"}
