Late model V8 and V6 engines that run factory light weight valve train components, are often subject to valve float in the upper RPM range, limiting the engines performance and full potential.  Yella Terra’s engineering team set out to find a solution to the problem, and the result was the Ultralite.

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, with the added advantage of improved strength and durability. 

Available in standard rocker ratio or high ratio options, to suit a number of late model engine applications.
