{"product_id":"sporttuned-heavy-duty-valve-spring-set","title":"SportTuned Heavy Duty Valve Spring Set","description":"These stiffer valve springs enable your valvetrain to reach up to an 8,000 RPM limit, significantly extending its capabilities beyond stock. Crucially, this set is designed to prevent coil bind when used with high-lift camshafts, and when installed correctly, they accommodate camshaft lifts of up to 0.500 inches.\n\nFor proper engine health and to prevent damage to the cylinder head's aluminum casting, it is important to retain the lower valve spring seats during installation. This upgrade is highly recommended for any enthusiast seeking to optimize their high-performance engine's potential.\n\nThe product details indicate fitment for various Volkswagen models, including Golf I (Convertible, Pickup, Rabbit), Golf II (All), and Jetta I \u0026amp; II (All), specifically for 8v engines. It is recommended to use the vehicle selector to confirm precise fitment for your specific application.","brand":"Autotech","offers":[{"title":"Default Title","offer_id":52687032615224,"sku":"10-109-600K","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661169022.jpg?v=1784879725","url":"https:\/\/store.motormia.co\/products\/sporttuned-heavy-duty-valve-spring-set","provider":"MOTORMIA","version":"1.0","type":"link"}
