Platinum

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. Stability and durability well beyond the chequered flag.

Complete with fully adjustable aircraft grade extruded aluminium arms, internally lubricating 2-piece shaft and all the necessary mounting hardware. Nominal 1.65 ratio.

Equipped with smooth low friction rollers allowing for high revving capability perfect for any street, strip, circuit or hill climbing application. CNC anodized cradle providing unsurpassed rocker stability eliminating premature valvetrain wear and radically reducing side loading.

Higher ratio rockers produce more lift out of a given cam profile. In addition, lift the valve off the seat at a much more rapid rate when compared with stock ratio rockers, producing increased airflow. Reliable at high RPM with huge needle roller bearings. Your engine will run cooler, smoother and quieter.
