YELLA TERRA - PLATINUM PLUS PEDESTAL MOUNT ROLLER ROCKERS

THE ULTIMATE ROLLER ROCKER FOR CANTERED VALVE BIG BLOCK CHEV

Yella Terra trademark design - positively retained pedestal with roll pin to orientate roller tips to any valve, eliminating the need for friction inducing guide-plates. Mounting hardware and roll-pin drill alignment tool included (illustrated)

Platinum Plus

Designed to withstand the harshest conditions an eliminate deflection caused by large open spring pressures. No other rocker system compares with Yella TerraPlatinum Plusrace 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” hardware for stability and durability well beyond the chequered flag.

Why Choose Platinum?

  • Oversize Wide body arms for greater strength and resistance to deflection, extruded from aircraft grade aluminum for the highest RPM potential. Built to withstand 900lbs + 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.
  • 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.

Includes 8 Specific Inlet arms & 8 Specific Exhaust arms for the perfect fitment along with Hardware to suit .250" longer inlet valves.
