Camshafts & Valvetrain - ZZP 1.9 Rocker Arms

This is our latest 3800 product. It is a lightweight replacement rocker arm, (over 27% lighter than the OEM rocker arms!) however this is the higher 1.9 ratio version, the stock rockers are 1.6 ratio. These are intended to maximize the performance of the stock camshaft by increasing the lift of the stock cam lobe. Increasing the lift of the valve will improve airflow through the heads resulting in about 5-7% more horsepower. They will reduce the boost a bit in supercharged applications which will reduce knock. These will work great in supercharged, turbo, or naturally aspirated 3800 cars. We also be offer them in a 1.65 ratio as well.

If your valve springs have less than 100,000 miles on them, generally they can be reused. However running 90# valve springs and LS style retainers will allow you to bump the shift point a bit more for more higher RPM gains and avoid valve float.

They come as a complete set, with the rocker arms themselves, custom pedestals, new rocker bolts, and a set of 5/16" chromoly push rods.


  • (12) rocker arms
  • (6) pedestals
  • (12) 5/16" 7.00 chromoly push rods (works with 6.95-7.00)
  • (12) rocker bolts

    Nice rockers

    My factory rockers were bad, thanks to the previous owner and laziness. I looked for replacements and came to the conclusion i could Upgrade for nearly the same price. Now that being said, the seat of the pants feel from these to OEM was minimal, the engine sounds healthier, deeper and over all better. But I am not going to say it turned the car into a fire breathing monster. I do plan on later putting a supercharger kit into the car, so current review is NA, also I am driving the heaviest of the breed. But overall I would buy these over stockers in a heart beat.

    Noticed a trend

    I spotted another customer with pedestal clearance issues as I did. After contacting ZZP they told me the pivots were not centered. this held true with 2 of the pivots but the real problem was the rockers had enough flash to keep me from mounting 3 of the assemblys. I went to my sons machine shop to clean up the rockers and allowed room for thermal cycling. Went together smoothly and along with all the other products from ZZP, IC , pulley and previous mods the car runs fantastic. I was always a skeptic on rocker ratio and valvetrain drag but this made a big difference! Good bang for the buck. ZZP is the perfect place for my GTP, thanks!!

    :( quality control

    3 if the rocker arm castings (pivots) contacted pedestals,which another reviewer commented on and would bind the operation. I was able th remove casting flash and install rockers. They will work great I’m sure,no doubt. It would be nice if zzp would contact manufacturer and address this. Some folks may not be able to fix rockers or will install them with defects. Love zzp and will continue patronage
