Hurst rattles no matter what you do Its not totally annoying but it shouldnt do that. The stiffer springs help prevent this but its BS in my opinion. I may cut the stock shifter and go with that. 170.00 for a rattleing shifter. The expense reward ration is out of proportion.
I recently installed my new Hurst in my 2001 Z06. I left the springs in the shifter that shipped with it and installed a new MGW knob. The noise from the shifter was horrible at all medium engine speeds and the side gate force was excessive, especially downshifting to first gear.
The next day I dismantled the console again and swapped the outer springs for the softer ones included with the shifter. I adjusted the screws afterwards. The side gate force is better, but still excessive.
All screws and nuts have Locktite on them. Then I decided to try a fix that I have heard about for noisy B&M Ripper shifters. I attached three strips of adhesive wheel balance weights to the shaft of the shifter; then I wrapped the assembly with electrical tape. The noise is now reduced, but still there. It is noticeable at mid revs and also at full throttle acceleration. In my opinion it is not acceptable for use in a street car.
A coulple of days ago, I sent an email to RG, wanting to discuss the problem and to get his assistance in resolving the problem. He must be busy, I haven't had a reply yet.
From what I see on this forum, the noise problem is a common problem with both the Ripper and the Hurst. Unless RG/Hurst can provide a repair to eliminate the noise, I believe that Hurst should take all of the noisy units back and refund the customer's money until they can develop a shifter suitable for Corvettes that are used on the street.
