FS: BNIB Yella Terra Ultra Lite 1.7:1 rockers
Yella Terra Ultralite Roller Rockers BNIB, never used, includes spacers, bolts, literature/install instructions and decals. Box was opened to verify everything was there. The accessories are still in their little sealed baggies.
Description:
After two years of R&D, testing and trials, the company has developed the Ultralite range that suits high performance applications. This new “proprietary lightweight design”. is better suited to performance hydraulic roller and mild solid roller applications. With valuable input from leading LS1 cylinder head manufacturers in the USA, Yella Terra engineers have worked in redesigning the YT Twin shaft rockers to withstand high RPMs and address valve control issues under extreme conditions.
The Ultra-lite shaft rocker has 50% less nose weight of other shaft roller rockers offerings, fitting under the standard rocker covers with no further machining required. The products come in both 1:7 and 1:8 ratios and use a full compliment high quality Torrington bearing set. The rocker body is machined out of the high grade aircraft alloy and roller tips have been precision machined. The rocker arms have been balanced to withstand the aggressive loadings at the high RPMS. The new Ultra-Lites will provide optimal results for LS series engines, provided the right valve springs and proper pushrod/valvetrain geometry is in place.
