Shaft mount rockers do not require guide plates.Extruded from aircraft grade aluminium, perfect for dissipating excess top-end heat.Adjustable kits are designed for use with both hydraulic and mechanical (solid) lifters. However, you can find a downfall, with the LS engines already having a 1.7 rocker ratio. YELLA TERRA 5/16' SHAFT MOUNT ROLLER ROCKERS HOLDEN 253-308 V8 1.65 RATIO YT5032Yella Terra Roller Rockers have proven to be so reliable and durable since 1983, with the ultimate in design and proven by official Holden racing teams such as NASCAR, AUSCAR and Commodore cup to give more power and reliability than other products. 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.

Hydraulic kits are designed specifically for use with hydraulic lifters. Shane Pochon of Lunati adds, Compared to the older small block 350вЂ™s and LT1вЂ™s, the LS1 has better springs and rockers, and the cams have a lot bigger bearing journal that allows you to run a bigger barrel, which helps make it a LOT more stable. Yella Terra Ultralight Rocker Set, Non-Adjustable, 1.7 Ratio is better suited to performance hydraulic roller and mild solid roller applications.

Yella TerraвЂ™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 TerraвЂ™s engineering team set out to find a solution to the problem, and the result was the Ultralite.

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. Manufactured and assembled in Australia using the highest quality materials. Yella Terra Ultralite is ideal for high revving street applications when coupled with factory/lightweight aftermarket springs.
