Yellaterra Sb Chev/Ford V8 Street Terra 7/16" Stud [1.6 Ratio] Rockers

YELLA TERRA - STREET TERRA

PRODUCT DESCRIPTION

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.

Street Terra

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.

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.
