4.56 gears

[Richard Lake]

I had somebody install 4.56 gears in my ZR1. Now i notice a small vibration only on deceleration from high speed (120) I told the guy who installed the gears he told me this was fine and it was because theese gears have such a small pinion he also said he set them up for strength on accel. Is this a problem should I be worried ? I never had the problem before gear install.

Hello, and welcome to the forum.

I don't know the answer to your question, but why not check with a performance shop and see what they think, like SGC.
