Differential Girdle

Differential Girdle
What ever happened to that thread about the guy with the custom girdle for the rear diff? I was looking to see if there were any updates and now I can't find the thread. I was really interested in what something like that would cost.

The differentials on the 1st gen Vs tend to separate (break) the case's snout side between the pinion bearings and the ring gear. It's literally forced apart at that point, with no girdle design being able to help that situation.
You hard-earned cash would be better spent on axles to help tame the hop inherent in the irs.

Yeah I have no idea where that thread went. It looked like a good idea in theory. It basically covered the whole diff from the pinion back. I think i'm just going to go all out with some DSS axles and the latest generation diff when mine decides to go kaput. I bought the car in 2008, and I have no idea if the diff is the original one or not. There wasn't any differential replacement on the warranty claim info(but there was a transmission replacement 1500 miles before I bought it...right before the warranty ran out). Who knows it's holding up fine so far...

A girdle would help, but to what degree is the question. No matter what, having extra material bolted to the snout that wraps around and bolts to the side and maybe even to the foward and rear mounts would help distribute the load. As the case start to be forced up it would be pulling on the side of the case as well instead of just the front. I can't help but think it would help. It's still a band-aid but hey, it's better than nothing. I think the axles and girdle together would make a pretty stout combo.

Yeah the one that was in that thread was basically a giant steel bracket that was attached to just about every bolt on the diff. It basically encased the entire thing in steel, with a cutout on the bottom for the drain plug, and a cut out in the back for weight savings. It looked like it had been cut out with a torch or plasma cutter, and was painted red. Not the greatest as far as finish goes, but it looked like it would definitely redistribute stress evenly throughout the whole setup.

The girdle type I was referring to was the rear cap-reinforcing type.
The one you're talking about must be the Corvette IRS cage-type.
I would think that taming the hop (with rear shocks and axles) will go a long way towards rear end reliability and should still be the first step.

I tend to build my cars in reverse by doing all of the driveline mods before putting a bunch of power down. I don't want to put in a 500HP 383 and only be able to enjoy it for a week because my differential and tranny exploded after a hard 1-2 upshift. I'd rather focus on getting the power that my car makes now to the ground in the most effecient and reliable way possible. HP and torque don't mean squat if you can't get it to transfer into forward motion.

I dont think anyone with hendrix or dss axles has broken a rear year...although there still hasnt been many drag radial passes put on those setups yet. I think the gen 3 rear with good axles and stiff bushings is the answer. $1800 for the gen 3 rear and either $300 or $1500 for axles and you are set.

Even if you still get hop, you can still break a diff on a 1st to 2nd shift. I did
others have too with aftermarket axles .
I would suggest if you realy want to drag race the car that bad you need to buy a gen 3 diff and some dds full axles.
If you want to just do some burnouts for your buddies then You can buy a eco axle and you wont get hop. But at the track or even with sticky tires you can blow a diff.
The gridle idea is good but Im not sure I'd depend on it 100%. its more like a band aid for alittle extra security, I wouldnt call it bullet proof.
Theres a guy that made the steel case but the cost is 2,900. Id have to lose my mind to spend that on a diff . But if you serious about drag racing then go for it

Yes that's the one. he had a second piece that covered the bottom as well. I agree with it being a band aid, but it's better than nothing, and probably a whole lot cheaper than a custom steel diff. I thought the steel diff was selling for $5k even.

I'm going to build some, I just need a diff as a template. Anyone selling an empty case or one with some damaged gears? (or giving one away with the hopes of getting a girdle/cage in return?)
They can be expensive jigs
