We are currently out of stock on all Yella Terra rocker sets for the Series II/III engines. Yella Terra is working on the next batch, which should be in the US by mid-March. You can still place orders for rocker sets, but please note that they won't be available to ship until the Spring.

These roller rockers are the lightest on the market with each rocker arm weighing only 6 ounces. They will produce more power with less valve float and include pushrods which are 10% lighter than stock.

Why choose Yella Terra Full Roller Rockers?

-- Great Strength
The rocker arms used on Yella Terra and Street Terra roller rockers are infinitely stronger than standard pressed steel arms providing the best in resistance to bending and breakage under high spring pressures at high RPM's. Pressed steel rocker arms, in high performance applications, are prone to failure, A high rate of fulcrum wear, flexing, cracking, splitting and breakage are common problems that will result in power loss or possible piston failure due to detonation of the incoming air/fuel charge. Other Yella Terra rocker components such as the trunnions, posi locks and bearings greatly enhance valve train durability in performance applications.

-- Reduced Valve Guide & 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 maintain efficiency longer.

-- More Power Through Less Friction
The use of needle roller bearings at the rocker fulrcum combined with roller tip at the valve greatly reduces horsepower robbing friction in the valve train to provide a measurable power increase over standard rocker systems.

-- Reduced Heat
The reduction in friction with roller rockers has additional benefits of reducing the operating temperature and foaming effect of engine oil to provide a cooler running engine.

- We recommend the use of LS6 Medium Load Valvesprings with 1.90:1 ratio Yella Terra Full Roller Rocker Arms to help reduce the chance of your motor having valve float.

- No special tools are required for installation with the exception of a 1/4" male hex driver and a torque wrench. Simply torque the rocker arm bolts to 25 foot-pounds and the valve cover bolts to 89 inch-pounds.

- We recommend your Yella Terra Full Roller Rocker Arms be installed by a competent professional. These parts can typically be installed with normal hand tools in 2.0 to 6.0 hours, but much care is required and there is opportunity for things to go wrong.

- When you make the best product you can offer a warranty to match and Yella Terra brand rockers are guaranteed to the original purchaser subject to correct fitment and production of the original invoice against breakage of the arm, shaft or trunnion and posilock FOR LIFE.

- If aftermarket valvesprings are used, they must retain the stock type conical (beehive) shape or valvespring to rocker arm clearance problems will result.

*** Yella Terra Full Roller Rocker Arms will fit any 1995-present 3800 Series II engine, or 2004-present Series III engine. No piston or cylinder head changes are required to use the 1.90:1 rockers. We recommend the use of LS6 Medium Load Valvesprings with 1.90:1 rockers.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Decent mid range power

DCClark (Mary Esther, FL) 5.19.2021

installed these on a new L67 long block from Summit racing with about 10,000 miles on it now, full size intercooler, long tube headers CAI with a 3.2 pulley with no KR, car always ran in the mid 13's on street tires, but haven't taking it to the track with these installed yet. Not much difference until mid range when there is a little difference but nothing big. Stock heads can only take so much air. Should knock off a few 10th's

5 out of 55 out of 55 out of 55 out of 55 out of 5 Good quality

Alex Armga (Ripon, WI) 5.19.2019

I have installed about 20-25 sets of these over the years including the set on my IS4 cam. None have given any bit of trouble. Feel confident that these will last you the life time of your vehicle! Donít forget a lifetime warranty!

5 out of 55 out of 55 out of 55 out of 55 out of 5 1.9's and LS6 springs

justin (Hamilton, Ontario) 12.12.2011

I installed these parts about 5 month's ago and was very happy with the products i received. Power gains were noticable. exhaust tone was changed slightly and was pleased with the change. No ill affects came to my car after doing this. If given the opportunity to decide on doing this again I would if I knew how good this product was and the level of quality it posseses. I would recommend this performance upgrade over doing a cam to anyone who still needs their car to pass goverment emissions testing.
