We replace the worn torque tube and shaft bushings for a tighter, smoother shift than factory. Use with your factory shifter or any aftermarket shifter for the tight smooth shift you want that won't wear out.
Lifetime Warranty
Delrin Torque Tube Bushings are stiffer than polyurethane or factory rubber but dampen vibration and road noise better than solid mounting.
Factory shaft is reconditioned, bushings are replaced with #SKF Needle Bearings and seals for a smooth shift that will never deteriorate.
Aditional seals added to keep debris out.
I rebuilt my first shifter box on my C5 about four years ago, (at about 80k) the car has almost 200K on it now. I did my C6 about 30K miles ago and I've done four other C6's as well. I've seen terrible looking bushings in cars with as little as 40K miles on them and I'm confident enough with the turn out that I'm happy to guarantee my work for the life of the car, no matter what.
Whoops, I guess that's kinda important, sorry. The rebuilt box is $145.00 shipped, I use USPS Priority 2 Day shipping. There is a $100.00 core charge. If you send you box in I can have it rebuilt and back in the mail in a day or two.

do you keep any of these stocked? If I'm up in your area that maybe something id be interested in is to just swap mine for a finished one to avoid down time of my car as it is a daily.
Yes, if it's your daily driver, mine always have been, just pay the core and I'll send you one that's ready to go. Send me your old one when you get them swapped and I'll refund the core charge.
A few more pics.

Reason: adding some pics. .
So I have a question you'll probably be getting soon anyway. I have a ZO6 with a lower box that has no rubber bushings on the connection to the torque tube. It's straight solid mount. So what are your recommendations for this?

I've had it go both ways, it's up to you. If you want to keep the solid factory torque tube bushings that's fine, I'd you want I can replace them with my delrin bushings. Besides that I do the same thing, replace the factory shaft bushings with needle bearings and add seals.
Personally I'd replace them with delrin, but that's totally a personal decision, the delrin absorbs a small amount more vibration, but not much. As far as that goes you might not notice a difference, but the shaft will ride much smoother and stay that way for the life of the car.
I warranty my boxes, all the parts, everything, for life, I don't care if you by a car with it, total the car, whatever, it's covered.

FWIW, GM moved away from those solid brass bushings on the C6Z in 2010 due to cust complaints about shifter rattles. 2010+ C6Z's use the base/GS lower box bushings. I have an '09 C6Z, but never had a rattle in mine except for the time I installed an LG shift **** with the integrated M2W button. Rattled so bad, I removed it in a matter of days.

Some people like them hard mounted, some don't. It's all a matter of personal preference, that's why I offer two of what I have found to be the best of both alternatives. Delrin being harder than Polyurethane, but softer than solid, both being better than factory rubber. 😨 wow I know so many options, what's important is they are all better than a sloppy factory box.
SUBSCRIBED!! I have an 02 ZO6 and the solid bushings have never given me any vibration issues with the stock ZO6 Shifter or the KIRBAN Shifter I have now.
I perfer the solid bushings.
My wife has an 11 GS and I may do the upgrade to hers when it needs it and use the derlin bushings for that project.
Thanks Bill, if you want we can leave the solid torque tube bushings in the Z06 and just replace the bushings on the shaft. If you have more than 20K miles on your car you'll notice a reduction in the slop in your shifter from replacing those. The factory bronze bushings are really just consist of a sleeve in the aluminum shifter box housing (in the rear end) and in the plastic end cap. Replacing those is with bearings will make your day. I took a video of how most of them look when I take them apart, I'll post a quick vid to give you an idea of what it probably looks like in your car (well, most people's cars) , in the next post, gimmie half hour.
