{"product_id":"550-lift-gen-v-lt-beehive-valve-spring-set","title":".550\" Lift Gen V LT Beehive Valve Spring Set","description":"The Brian Tooley Racing (BTR) .550\" Lift Gen V LT Beehive Valve Spring Set (BTR91120-16) is engineered as a direct replacement for the factory valve springs found in a range of Gen V LT engines, including the L83, L84, L86, L87, L8T, and LT1.\n\nThey provide 95 lbs of seat pressure at 1.870 inches and build to 300 lbs of pressure at 1.330 inches. The spring set has a coil bind specification of 1.280 inches and a rate of 386 lb\/in, suitable for lifts up to .550 inches.\n\nBTR advises against using these single-wire conical or beehive springs with roller rockers due to potential valve train instability from increased mass, or with higher ratio rockers that could lead to coil bind. For specific roller rocker combinations, contacting BTR's sales team for clarification is recommended.","brand":"BTR","offers":[{"title":"Default Title","offer_id":52687276704056,"sku":"BTR91120","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660682641.jpg?v=1784882126","url":"https:\/\/store.motormia.co\/products\/550-lift-gen-v-lt-beehive-valve-spring-set","provider":"MOTORMIA","version":"1.0","type":"link"}
