This lightweight spring is Katech's default choice for their engine packages and was identified through Optron valvetrain dynamics testing as the best option for controlling lightweight valves, such as those found in LS6 and LS7 engines.\n\nKey specifications for the PSI 1511 ML include a 1.290\" outer diameter, 0.630\" inner diameter, 130 lbs of seat pressure at 1.800\", and 370 lbs of open pressure at 1.175\". It has a rate of 384.0 lbs\/in and a maximum lift of 0.625\". Katech recommends a coil bind clearance of .050\" for optimal performance with this valve spring.\n\nThis set requires a set of 16 springs. The PSI 1511 ML springs are designed to be direct drop-ins for stock applications, meaning existing supporting hardware can typically be used.","brand":"PSI 1511ML","offers":[{"title":"Default Title","offer_id":52663381655864,"sku":"PSI-1511ML","price":299.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687530528.jpg?v=1784326411","url":"https:\/\/store.motormia.co\/products\/1511-ml-high-lift-beehive-valvespring-set","provider":"MOTORMIA","version":"1.0","type":"link"}
