Hydraulic kits are designed specifically for use with hydraulic lifters.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. Yella Terra’s engineering team set out to find a solution to the problem, and the result was the Ultralite. While that means more lift for any given cam lobe profile, it also means that more power isn’t as easy as a rocker swap. The stockers have also been increased from a 1.5 to a 1.7 ratio even to a 1.8 on the LS7.

Late model V8 and V6 engines that run factory light weight valvetrain components are often subject to valve float in the upper RPM range, limiting the engines performance and full potential. When comparing LS rockers to SBC rockers at a stock level, the LS version are stud mounted to the cylinder head. Manufactured and assembled in Australia using the highest quality materials. When fitting YT Adjustable Rockers to LS1, LS2, LS3, LS7 & LSX based engines, the heel of the rocker may require clearance at the inner edge of the cylinder. Yella Terra Ultralite is ideal for high revving street applications when coupled with factory/lightweight aftermarket springs.
