How to install Yella Terra High Performance Roller Rockers for the LS1 Engine

Over the past several years the GM LS series engines have gained fame and supremacy in the performance arena. Arguably one of the most productive and necessary modifications is the installation of aftermarket roller rocker arms. The instance of needle bearings falling out of the factory rockers is astronomical and bearing replacements have not solved the problem. The Yella Terra easy fit, Ultralite, shaft mount, roller rocker arms are among the strongest and highest power producing rockers available today. They are also one of the easiest to install. On average power gains of 20 horsepower and 20 foot pounds of torque are produced. Valve stem wear is significantly reduced by eliminating side loading of the valves and rocker arm deformation is almost nonexistent.

Yella Terra is considered to be the leading hi performance engine components manufacturer in Melbourne Australia, supplying the Performance and Racing Industry with high quality valve train products for over 50 years.

The company is recognized as the country's largest and leading manufacturer of high performance engine components, continuously investing in R&D and meeting the demands of motorsport.

All Yella Terra Roller rockers are 100% Australian designed and manufactured with US sourced components and have been applauded by engine builders in Australia and the US, requiring maximum durability for road and race applications. They are built to withstand the torture of marine, speedway, drag racing and long distance
endurance racing.

Many US Performance and Racing companies have been so impressed by the quality of Yella Terra; they have sourced them for sale under their own famous brand names.
The Yella Terra Brand is more than just a well known international icon of high performance engineering... it's an institution.
