Why Yella Terra Rockers?

Reduced valve guide and seat wear
The traditional metal tip on standard rockers literally drags across the valve tip as the rocker opens and closes causing high side loading on the valve. This inside force leads to irregular and rapid valve, valve guide and valve seat wear in many engines. The roller tip on Yella Terra roller rockers eliminates this side loading action, as a result engines rev quicker and freer with a crisper exhaust note and maintains peak efficiency longer.

Reduced friction
The use of needle roller bearings at the rocker fulcrum combined with a roller tip at the valve greatly reduces horsepower robbing friction in the valve train.

Component strength
Yella Terra aircraft quality extruded arms are the strongest made and are matched to massive ground trunions for superior durability to other brands. Oversize needle roller bearings are used for better load distribution. Yella Terra uses premium quality materials, carefully controlled heat treatment and precision grinding and finishes. This ensures reliability, minimum friction and long life.

Can you, or will you sell a pair of these for the LS7, verse a whole set? There is an on going effort by some of us to have some Spintron testing done by Ketech. One of the desired tests is a bolt on roller tip rocker for the LS7.

Do these fit under stock valve covers?

I will speak with the owner about this and see what we may be able to help with, but that is not my call.

They will if you purchase the Yella Terra Valve Cover Seals.
