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.
