Try cutting a tennis ball in half, take a knife and make an X cut at the top, and then slide it down the shaft. With the tennis ball mod and my MOMO shift, I have no noise or rattle problems.
Well...I tried the tennis ball solution...it didn't work for me at all. It looked good after I installed it, but within a week or two, the tennis ball half traveled up the shaft. Everytime I shift into a forward position the tennis ball put stress against the OEM rubber boot below until it began to tear. I have ordered the Hurst B1 boot discussed above and believe this to be the best solution for the boot. But as far as the vibration issue, you need to find a shift **** that is one piece billet aluminum or steel ball or handle which will screw down tight on the shaft. A set-screw is even better with some locktight. Even after all that, you'll probably still have some small amount of vibration noise. Good luck to you....I think I must be getting used to it now.

I contacted Hurst last year about it. They stated the Hurst shifter is a performance item and does not have the dampening material as the OEM shifter does. They have no intentions to dampen this shifter for noise because performance part items are not concerned about noise, only performance.
When you think about it, this makes sense. We tend to mod our C5's with performance parts and then expect it to be OEM quiet, it just doesn't work that way.

OK...In other words, "Go F&^%$ yourself."
"We have enough customers who buy this and won't return it because
of noise."
This just means they will put no effort or engineering into coming up
with a simple solution.
Even GM can dampen noise and vibration with a POS shifter.
There are other aftermarket shifters which deal nicely with this problem.
If I ever get to upgrade, it will be another vendor.
You guys are missing the point about the product and most performance products in general. They are not luxury items, they are PERFORMANCE items for racing. Their main function is only for performance, Hurst did not mislead us. We took a racing product and are using it for street use. The hurst shifter, as with all performance short throw shifters, is that they are not concerned with noise dampening. If that is your primary concern then stick with the OEM shifter.
I knew about the noise and rattle going into a performance shifter and chose solid shifts over noise. I looked over the threads and learned many found ways to dampen it. The best and easiest thing I did to remove the rattle was using an MGW ****.
Guys....I installed a 3" long x 3/4" piece of new heater hose over the shifter shaft. It has worked well for me and several others I have done it to, hopefully it will work for you. Also the hose has been there for two years without moving (pushed onto shaft dry)

...I agree...
I have reduce the noise as much as possible...
...now I accept the performance of the HURST with its characteristics...
...and I enjoy the performance over its characteristics...
If I didnt like the characteristics more than I wanted the performance...
...I would have stayed with oem shifter...
now...whats all this to do with cruising when you have the exhaust pipes tuned to loud...and the radio blaring in the background
On this Fernco Rubber Plug mod....it goes on upside-down, with the "cup" portion facing up, right ?
I bought the plug today, going back for the 4 inch piece of 3/4" heater hose tomorrow and I am going to fill the "cup" portion with some sound deadening material. I will also use the teflon take on the **** threads. Have the MGW **** already. I will report back with some pictures and impressions.
Not the leather outer boot...the one that bolts down around the shifter under the leather boot. I would like the part # for the one that does not have the hard plastic ring imbedded like my 2004 did. Reason being is when I installed the Hurst originally, I cut out the ring as required to invert the boot around the larger Hurst base. Well, now I just took it apart and the boot has ripped in three places making it useless for the Fernco Plug mod
I think that the cutting left it more suseptible to tearing. Anyway...anyone know the GM part # for the part that does not have the imbedded hard ring ? and what years did not have the imbedded ring ???
So the car is apart waiting for the new boot to be ordered, and of course this was right after a 6 hour detail session.
The plug goes in as you describe - with the cup portion facing up. Take a look at the pic I posted on the first page of this thread. The isolator base I put mine in still has the hard ring embedded in it so you cna use that one. The part no. is 12555226.
Make sure the hole you cut in the plug is smaller than the shaft diameter so the shaft is held in place by the plug. The tension is what helps to keep it from rattling.
I don't think it's the shifter but the design... It's a great piece, i just need to work on it. Thanks tho George.
And to get rid of that rattle in the tranny... DYNAMAT!! I hated that sound of the car "dying" when you turn it off (that rattle inside the shifter area when the car is turned off) so I dynamatted it all and every sound inside the tunnel is gone... now onto the shifter...
The owner's manual says to stop the car in reverse gear and you don't get the rattle.
Press the clutch in when you turn the ignition off and it'll shut off with no rattle. It disengages the pressure plate, loading the slave and the rattle is not transmitted down the torque tube to the tranny.

Patches...got my new (stock) base....how in the world did you invert it with the hard plastic ring inside....I just can't seem to do it...this puppy is tough...although the rubber is very soft....?????
Work on it for a while - it'll filp. You need to keep at it until it's reversed. The hard ring never really recovers from the trauma - it stays kinda' warped until you insert the plug (hmm, that sounds kinda' strange . . .). Don't give up.

Well, I gave up...cut it off and finished the mod.
I used a 2" Fernco cap, with a 9/16" hole drilled in the center and slid it down the Hurst shaft. Fits tights and I like the look.
I then slid a piece of 3/4" rubber heater hose down the shaft to isolate noise/vibration further. As an added bonus the heater hose holds the Fernco plug down in place very well.
I cut the hose to 2 7/8" length. This allows the heater hose to "sandwich" and push the Vette Essentials boot up into the bottom of the MGW Gripper ****.
I added the teflon tape to the threads as well before installing the ****.
The Hurst is now very, very quiet. Thanks Patches and every one else for the ideas.
I solved it!!! I finally got out to drive today, really weird 70 degree weather, had the top down, and no noise!!! I realized I rarely drive with the top up and with it down, you can't hear the rattle!!! Thanks guys
Also, I got one of these pipe plugs in the plumbing section at Lowes and it quelled all noises once and for all.
I just did this last night as well as the teflon tape. I hadn't checked in on this thread so I missed out on the heater hose. Things are really quiet now! No rattle and the plug really keeps the tunnel noise out.
One negative side effect is that it's now harder to shift. Anyone else feel this? I have the plug installed as shown in Patches' photo. I put it as far down on the shaft as possible so there would be less movement of the stick for the rubber plug to have to work against. I may reduce my spring pressure on the Hurst now and see how it counter acts it.
