Product Description

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.

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.

Why Choose Street Terra? 

  • Vaccuum die cast arms built to withstand 450lbs* max open spring pressure
  • Oversize full-complement caged bearings designed for oscillating (rocking) loads, paired with oversize precision ground trunnions to reduce friction.
  • Proven bolt-on shaft mount design that mounts both inlet/exhaust to common shaft, effectively increasing footprint and clamp load twofold without any further cylinder head modification.
  • Stud mount also available.
  • Various ratios available, catering for every camshaft grind. High ratios allow for additional lift on stock and aftermarket camshafts.
  • 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.
