Yella Terra’s Pro Street shaft-mount roller rocker system is designed for high-revving street and strip Holden EFI V8 combinations using VN-style cylinder heads. The 1.65:1 adjustable full-roller design uses the heavy-duty bearing and trunnion architecture derived from Yella Terra’s Platinum race series.

1.65:1 rocker ratio.
Supplier-rated to less than 600 lb maximum open spring pressure.
Oversize full-complement caged bearings and precision-ground trunnions are designed for oscillating rocker loads.
Balanced CNC billet / aircraft-grade aluminium arms provide strength with controlled valvetrain mass.
Hardened and ground chromoly roller tips reduce valve-tip and guide wear.

Maximum spring diameter: 1.437 in.
Shim set included.
Suitable for hydraulic and solid camshaft combinations when set up correctly.

Easy-Fit configuration: Uses the factory-size 5/16-inch bolt-down mounting points and is designed as a direct shaft-system replacement without cylinder-head machining.
