BTR LS .650" Lift Max Pressure Dual Valve Spring Kit With Titanium Retainers (For Roller Rockers)

BTR’s Max Pressure Spring Kit applies what we learned when designing the Platinum Spring Kit (SK001) and applies it to applications utilizing roller rockers. Due to the additional weight of roller rockers, a higher spring rate is needed to retain valvetrain stability. This is a drop-in kit for 15° LS heads utilizing roller rockers or track only applications with stock rockers. It will also work with LS7 heads when used with a .045” shim (Part numbers SS015 +SS030). This kit will not fit LS9 engines.
