Stock 07 rear? How strong

[TerminatorSVT03]

Curious to see how strong the stock 07 gt500 rear is at the track on a tire.
I don't plan on launching off of a 2 step or any clutch drops lol but my car makes a little over 700 rwhp and a littler nervous about the rear. From what I'm hearing it's a 31 spline rear but wanted to get other people's first hand experiences with it

Weakest link in the drivetrain. I even upgraded to a Torsen and broke that too

Forgot to mention I have a one pc dss driveshaft also

One piece driveshaft doesn't make the rear any stronger

I broke my factory 3.31 gearset at stock power levels with a MT DR the first summer of racing. After the replacement I haven't had any additional issues and have got about 55 drag passes at elevated power levels. That said, I run the car a bit soft out of the hole, 1.7 60' and haven't used a proper slick yet.

8.8" axles have been used anywhere from 500-1000 BHP with success but a lot rides on the exact combination, driving style, and available traction.

Work hard enough and smashing a built 9" is no great feat either, it can happen.

The 31 spline isn't an issue. The diff is. Buy this

Weld the tubes.

Done, unless you're John Force.

I'm well aware I wasn't making it known before someone says " I wouldn't worry about you Rear if you still have a stock ds" lol

That's what my plan was lol weld the tubes and put my ford racing 3.73's in and leave soft and pray for the best lol

Once I build the rear I'll go with the tru trac. Heard a lot of great things about it

I have run my car at several test and tune events and a private track rental just for fun. I am at about the same power level with stock 3.31 gears and 27" drag radials. I launch at 3000 rpm just letting the clutch out with no bog or wheel spin and haven't had any issues. I would not launch at 4000 rpm at this power level with a stock rear.

That's pretty much what I was looking for lol thanks for the input.
Like you said a nice 3k slip is all I want to do just to feel the car out. Once I build the rear then it'll hopefully see some 1.5 60's lol
Which track do you go to?

Here's my car snapping a stock axle on a 31 spline Truetrac at just over 700 HP:

The Truetrac looked like a busted pumpkin. I put in a new Truetrac and Moser 31 spline axles and twisted them in no time.

I've been poking around various shops in the area. A lot do not weld the tubes. :sleeping:

Which track do you go to?

I have run at Famoso in Bakersfield, CA, Capital Raceway in Crofton, MD, and MIR in Southern MD. MIR has the best track prep by a great margin.

What's a good axel and diff combo then? Lol do a lot of poepl just go 35 spline ?

I went 35 spline from Strange. Welded on 9" ends. I'm using a spool and I am not having issues on the street for my style of driving.

The feeling of being "bullet-proof" is great! I believe it helps me mentally improve on my 60' times. One less thing to worry about.
