By concentrating more mass at the fulcrum, the Ultralite Pro can withstand a much heavier spring than the Ultralite without compromising any oscillating weight. 10mm bolt down versions are available, in addition to the factory 8mm easyfit (EF). Intended for those who need lightweight rocker arms but insist on heavier springs! Yella Terra’s exclusive Ultralite rocker arm, shaft and pedestal system offers 50% less nose weight than the factory rocker system, the result being greater RPM potential without compromising strength or durability. The perfect low-maintenance substitute for factory rocker arms which utilise problematic cage-less bearings, solid non-roller tips and heavy steel bodies. Yella Terra Ultralite is ideal for high revving street applications when coupled with factory/lightweight aftermarket springs. Manufactured and assembled in Australia using the highest quality materials and componentry consistent with those found in our Platinum race series. A 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. Don't fall victim to bearing/trunnion upgrades which only address half the shortcomings of OEM rockers. Includes YT 5132 10mm valve cover spacer.
