{"product_id":"beehive-valve-spring-set-650-lift","title":"Beehive Valve Spring Set .650\" Lift","description":"The PSI Beehive Valve Spring Set (1515ML) is engineered for high-performance LS engines, specifically designed for applications requiring up to a .650\" lift. This set utilizes an advanced, in-house nitriding process that enhances surface strength while maintaining core softness for improved durability and resistance to fatigue. This makes it an excellent choice for demanding racing environments such as Circle Track and Road Circuit racing, where longevity under stress is critical.\n\nKey specifications include an outer diameter of 1.290\" and an outer ID of 0.640\". The springs offer 140 lbs of seat pressure at 1.950\" installed height and 405 lbs of open pressure at 1.300\". The rate is 408.0 lbs\/in, with a maximum lift of 0.650\" and coil bind at 1.225\". The nitriding process provides better wear resistance, reducing the risk of spring failure. However, due to the slight reduction in core hardness from the nitriding process, these springs are not recommended for drag racing use where maximum stiffness is prioritized.\n\nThis valve spring set is compatible with a wide range of GM vehicles, including various generations of Camaro, Corvette (C5, C6), Cadillac CTS-V, Chevy SS, G8 GT\/GXP, GTO, and GM Trucks (1999-2007, 2007-2014), as well as the Trailblazer SS (2006-2009).","brand":"PSI \/","offers":[{"title":"Default Title","offer_id":52663381590328,"sku":"PSI-1515","price":365.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687530523.jpg?v=1784326411","url":"https:\/\/store.motormia.co\/products\/beehive-valve-spring-set-650-lift","provider":"MOTORMIA","version":"1.0","type":"link"}
