Stud Mount Traditional stud mount rocker designed to either use original factory 3/8 press-in studs or 'screw in' 3/8-7/16 aftermarket rocker studs. If fitting screw in studs, machining is required. Pro Street Designed for high revving street/strip applications. No other comparable product can compete with 600lbs* maximum open spring pressure whilst retaining factory size bolt-down hardware. Manufactured and assembled in Australia using the highest quality materials and componentry consistent with those found in our Platinum race series. Our wide range of true ratios allows you to achieve high lift without relying solely on your camshaft… a trend many engine builders and racers alike are adopting to relieve the inertia on lifters and pushrods generated by aggressive and often violent ramp rates required to make big lift.
