Yella Tarra LS3, L98 Rocker Arms, Non-Adjustable, 1.7-1.8 Ratio

Yella Terra Ultralite hydraulic shaft bolt on roller rocker set, to suit LS3/LS9/L76/L77/LY6/L94/L92/L98/LC8/LC9/LH9/LMF/LH9. These rockers are a "bolt on" and require no machining. The come as a complete set with all hardware including the rubber spacer/gasket for additional clearnace that may be required if using factory rocker covers.

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.
