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. The best value rocker arm on the market today. Engineered to meet or exceed the needs of performance street and sportsman race applications. Our vacuum die cast arm is designed and engineered for optimum strength without the costs associated with billet CNC machining. The Street Terra series utilises the extreme duty hardware from our premium Platinum race series - ensuring a lifetime of trouble free performance. Our easyfit (EF) kits are a cost effective alternative for factory stamped steel rocker arms, which can be installed within less than an hour without cylinder head removal and in most cases without machining. 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. Popular amongst standard rebuilds where OEM equipment is worn and or scarce, as well as mild street applications.
