I did a search and didn't find anything. Are the torque boxes weak on the 94+ cars like they are on the 79-93 Foxes? I want to know if I will need to upgrade them on my Cobra or not once I get DR's for it.

I reinforced mine. I have seen a 300rwhp car rip the torque boxes on the street on drag radials. So I decided to go ahead and reinforce mine.

IIRC Ford made significant improvements to the torque boxes on the SN-95 cars.

Well I know it is a problem on Foxes, but I've never seen anything on the SN cars. I even did a search and came up with nothing.

If your cobra has a solid axel then I would. However if you have an IRS I wouldn't worry about them for a while because the tq boxes dont take as much of a beating because the irs subframe bolts to both the lower tq boxes and the frame rails by the gas tank.

It's been converted to a SRA. I was hoping to be cheap and not need to do them. lol

Do it. Even the bolt in kits are better then nothing. I know a couple on modulardepot had problems with them back in the day. Over the winter I will buy a bolt in kit then have them welded.

Having a SRA conversion I would go ahead and drop the cash and have a set welded in. A torn tq box can be repaired but it could potentially cost you more then just having the reinforcements put it.

I am doing just lowers but I won't have upper control arms. If I did I would do both.

The upper and lower torque boxes should be reinforced on a car that will be launched frequently on sticky tires.

is welding the stock boxes good enough for h/c/i car or would a torque box kit be preferred and if so what brands are better? thanks for input

Well, I work at UPR Products, and we have a nice upper & lower torque box reinforcement kit, but if you're talking about a 300hp +/- HCI car, I think you could get away with seam welding the torque boxes.

Keep in mind that it's more about how much stress the torque boxes will see, rather than how much hp you have. For example. If you have a heavy 300hp stick car with a 31-spline rear end, 4.56 gear, and 28" slicks that is drag raced weekly, you could easily tear up the torque boxes with only 300hp. But if the car isn't ever raced on slicks or drag radials, I doubt you'd hurt them with 400hp.

But like other drivetrain upgrades, torque box reinforcements are cheap insurance. If you have the money, put em on there. You won't regret spending a couple bucks on durability.

Sharad, thanks for replying. I did look at the UPR product and it seems like a a good deal for the money. Is the kit easy to install,i could do just about anything mechanical but i am very new to welding and fabricating. how much more abuse can the torque boxes handle after a reinforcement kit like the UPR?

I've always seen the Wild Rides battle boxes being used by many people and they're pretty nice pieces.
Also, their sbox setup is pretty killer; although more fabrication for install.

I've never seen the UPR pieces up close; so I can't really comment on them.

No problem. Yeah, our kit is nice, and you get a 10% discount on our webstore as a member of Stangnet.

The kit is easy to install, and it can be just bolted in. However, after you bolt it in I'd eventually take it to a muffler shop that can seam weld everything. It shouldn't cost much.

I know this is a older thread, bit whoever says torque boxes reinforcements are easy to install should have there head examined. I agree there cheap insurance so u don't hurt them, but unless the rear is completely out and the muffler and tailpipes removed its a royal pain in the ass. And don't let anyone tell you differently.

Welcome aboard. I don't think anybody here had illusions. It's a good time to change the friction disks in the Trac-Lok too

P.S. Here's another torque box replacement kinda like the Wild Rides pieces listed above:
