YellaTerra Rockers (205194 views)
Yella Terra's shaft-mount rockers are an easy and economical way of boosting power, torque and reliability in late model engines. When Yella Terra bolt on rockers are used, the conversion can be performed in the vehicle with no head removal or machining required.

Yella Terra's shaft style rocker arms are suitable for hydraulic roller camshafts and feature oversize shafts and bearings for massive strength, stability and long life. No more needle bearings in your engine! Simply bolt on to original 8mm rocker mountings with no valve cover clearance problems! Eliminates studs, guide plates and special pushrods.

Essential Info:
Vehicle: C5 Corvette 98-02 F-Body

Review #1 by 66ImpalaLT1
Review:
I purchased Yella Terra 1.7 rocker arms in an attempt to quiet my valvetrain, with the secondary goal of replacing factory rocker arms before one of them spilled its needle bearings.

I've owned and handle many sets of rocker arms for other engines, and without a doubt Yella Terra makes a high quality part. I'm confident that the large lightweight body, and the large diameter shaft will provide long life in any perfomance application.

My only disappointment is that my valvetrain noise has not decreased. I may need to try using the shims, or different pushrods.

Review #2 by WCR_Timmy
Review:
I too bought these rocker arms in search of quieting my valvetrain noise, and having solid componnents all throughout the valvetrain. These rockers appear to be indestructible, but I have limited experience with aftermarket rocker arms. Unfortunately the valvetrain didn't quiet down as much as I hoped, but maybe nothing can be done for fast-ramp cams and dual valvesprings. I would only recommend getting these if you want a solid drop-in replacement rocker system for your modified LS1.
