Yella Terra Ultralite Pro Roller Rockers LS3 LS9 LSA L98 1.8 HYD Ratio YT6753

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. 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. 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. Compatible with No. 19201805
