Another option for the CTS-V rear end than a 9 inch, pics inside We built an 04 CTSV over winter that made 600rwhp... The rear end lasted 4 hours on the street and did this:
He just paid us a lot of money to build the car to have the power it has, and didn't have enough funds left over to install a Ford 9 inch, so we bought a new diff from GM and did this:
Unfortunately, we can not sell the parts as there is too much fabrication involved, so if you would like this done to your ctsv, it is for install @ New Era Performance only.

Can you post bigger pics? I mean not everybody can head all the way to NY to have a girdle made. It would be nice to have some bigger pics to get some ideas.
Thanks

Also, what kind of abuse has the diff survived since the girdle install? How long has the girdle been installed in the vehicle?
I may also add, you guys do great work. That thing looks really nice.

Looks nice...be curious how well it holds up and nice to have an option (idea).
Pics are tiny, but curious why you used (what looks like) spherical rod ends and jam nuts...is that for mock-up adjustment, or to make adjustments down the road? Perhaps the rod ends allow some flex, yet keep it rigid in the axis plane, if that makes sense?
Otherwise if somebody were to duplicate it, perhaps they could used fixed holes, to keep costs down [especially if you could simply drill thru tube & sleeve, etc.]

How many miles are on the V so far with this Diff set up? OR did you just finish it?
Great Job, I'm looking for Companies that are innovative and unique. Thanks for posting!
I hope this set up helps things out!

Thanks!
The links ease fabrication as you dont have to make that part out of steel now. Less cutting. Also, it lets you preload the case in the manner you want. If you want a little preload to pull on the pinion, just dial it in with the links.
The only problem I see is that the pinion always fails by climbing out of the case. As seen in the picture. When you tighten the links on this girdle, you are pulling up on the pinion. For this case, I would almost prefer not to have anything pulling up on the pinion as it is already weak to begin with. Instead, I like the one we saw that was made out of plate steel and no links. If there was a way to make the girdle so it would pull straight back on the pinion instead of pulling it up, I would prefer that. This is still better than nothing though. At least it ties more of the case together.

You guys do good work and I like the idea but I see this as a band aid and not a fix for the high hp cars.
This is my opinion but, I see the aluminum housing cracking where the links bolt up. If you could find a way to double shear those links I think that would help alot. That would require alot more work because of the aluminum. I've built a four link and you would be surprised how much movement you get out of hiems, tubing and brackets.
Thats my .02. Like I said I like the idea, and you have to start somewhere. Keep us posted on how it holds up.

We just finished it, testing starts today. Pricing depends on suspension upgrade options, and we have to use a 06-07 diff, so if you don't already have one, you will need one of those as well. It will range between $3500-$5500 installed depending on options, the pricing isn't set in stone yet. Some suspension upgrades are included, it is very labor intensive, takes about one week from start to finish. If you are interested in scheduling something, please call or email and we can better estimate something for you.
