Yella Terra Platinum Race Rockers - The ultimate performance rockers for Aussie V8's

Designed for strength, built to race. No other rocker system compares with Yella Terra Platinum race series. Manufactured and assembled in Australia using the highest quality materials and componentry sourced locally and from the USA.

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.

Proven bolt-on shaft design featuring heavy duty 7/16” and 10mm hardware for stability and durability well beyond the chequered flag.

Features and benefits of the Yella Terra Platinum Race Series Rockers for Holden V8 304 Injected cylinder heads:

Wide Body Arms

    • Increases strength and resists deflection at high RPM
    • Extruded from aircraft-grade aluminium for optimal rigidity and heat dissipation

High Open Spring Pressure Rating

    • Built to withstand up to 900 lbs max open spring pressure
    • Ideal for extreme race applications requiring ultimate durability

True Ratio Rocker Options

    • Achieve high valve lift without relying solely on aggressive camshaft profiles
    • Reduces lifter and pushrod stress, promoting longer engine life

CNC-Balanced Billet Arms

    • Enhances valvetrain stability and engine harmony
    • Minimizes vibration and uneven wear

Oversize Full-Complement Caged Bearings

    • Designed specifically for rocking motion, not just rotation
    • Paired with precision-ground trunnions to reduce friction and improve durability

Chrome Moly Steel Roller Tips

    • Hardened and ground for smooth valve tip contact
    • Reduces wear on valve guides and tips, maintaining valve lash and lowering maintenance

Heavy-Duty Shaft Mount Design

    • 7/16” and 10mm hardware increases stability under high loads
    • Bolt-on design suits both inlet and exhaust, no cylinder head mods needed

Multiple Ratios Available

    • Tailor lift and duration for both stock and performance camshafts
    • Allows for fine-tuning of engine performance without camshaft replacement
