YELLATERRA HOLDEN & AMC V8 STREET TERRA 3/8" STUD [1.65 RATIO] ROCKERS (ST 2009)

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.

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 Easy-Fit (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.

Chrome moly steel hardened and ground roller tips of generous diameter (positively retained by internal circlip) preventing abrasion of valve tips and guides commonly seen with non-roller tip rockers. Allows for smoother, quieter operation. Maintains lash and reduces necessary and tedious engine maintenance.
Head must be modified for aftermarket 7/16" screw in studs
