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. 

Ideal for harsh street and strip applications, especially in place of the factory stamped steel GMH rockers that have seen decades of wear and tear. These rockers have got what it takes to last!

Why Choose Pro Street?

• Built to withstand 600lbs* max open spring pressure
• Oversize full-complement caged bearings designed for oscillating (rocking) loads, paired with oversize precision ground trunnions to reduce friction.
• Intricately balanced CNC billet arms ensuring vital valvetrain stability - focusing attention on the harmony of the entire engine.
• Extruded from aircraft grade aluminium, perfect for dissipating excess top-end heat.
• 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.
• 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.

Easy Fit Shaft - Adjustable - Suitable for both HYDRAULIC and SOLID camshafts

The original "bolt on" rocker. Simply remove old rocker gear and replace with the shaft assembly that bolt onto the original mounting holes with no modification. Tremendous rigidity

When installing adjustable rockers, double cork gaskets or taller rocker covers may be required. Please check clearance exists between Lash adjuster & Rocker covers at maximum lift.
