I would think so bc my buddies 98 stang has been doing just fine with it. It's been to the track, doing hole shot on it, burn outs and doing a little bit of wanna be drifting action, and it's been spinning both tires the whole time w/o any problems what so ever. It's a auto single port with 3.73's fact. tloc from a ranger, cai, alum. drive shaft, coil pack w/ 9mm plug wires and udp's. I know his car may not have the split port power like the 99-04's do, but so far it's been doing one hell of a job.

He picked up the stock tloc for about $80-$85 shipped. Got the gear for about $60 shipped and got them put in for free. The only thing I would do is get a rebuild kit for the tloc just so you know that it is fresh.

the 7.5 t-lok won't hold up to a splitport with a 5spd for long. the spyder gears will take a crap. Taylor097 over on another board grenaded his 7.5 t-lok with only 212ftlbs torque. i have destroyed 2 of them with an auto at higher power but nothing great at 226rwhp267ftlbs. i've also blew a few 8.8 t-lok's on a stock 98 cobra and a bolton 02 GT.


some last most don't. like i said earlier a detroit truetrac and a full install kit in the 7.5 and you will never have to worry about the rear. adding a girdle and bearing cap stud kit will help keep case deflection to a minimum above 400rwhp on the 7.5

I still kinda beg to differ hear on the factory t-lock. My dad has had a 84 ranger long bed factory 3.73 t-lock posi. in the 7.5 and it had a 5.0 swap with a T5 5sp, 70mm tb, cobra uper and lower, 1.73 rr, custom long tubes, true duals, udp's, bigger maf, and 9in K&N, on 275-50-16 nitto dr's. The t-lock lasted many many many mid to low 13sec 1/4 passes with wheel hop b4 the traction bars were added, and then got sold but the guy put trick flow heads and a cam in it and the t-lock lasted about another 2 dozen passes on BIG M/T ET Streets b4 it blew out.

So the way I look at it if a cai, full exhaust, and geared v6 can tear a t-lock up on street tires then something is very wrong here. The guy isn't trying to make 400+whp he just want to spin both tires and hook up better than what he is doing now.

a few have lasted some abuse. mine didn't for long at all. hell my carrier is cracked as well as my crosspin on my second t-lok.

if you research the various V6 boards you can find a ton of blown 7.5 t-loks with not alot of power put to them. also the clutchpacks wear out quick. i went through 2 sets on my first t-lok in less than a year.

the detroit truetrac is far stronger and amuch wiser choice especially for guy's with XR4Ti's. they were known to blow the t-lok on the IRS 7.5 rear.

i have the truetrac now as well as many others and not one yet has broken. when ford hit 200hp in the HO 5.0 in the mid 80's they had to switch to the 8.8 because the 7.5 t-lok wouldn't handle it. a good differential in the 7.5 like the truetrac or locker and it will handle alot of power

I do understand what your saying about everything. I was just trying to think about the actual cost on hand. I just didn't think that they were that terribly weak. Since you have the more experience with the 7.5 I've just seen the few good things about them.

cobra232

the t-lok is for for a stock singleport and for someone that doesn't drive hard and wants better winter traction. they do work great for that.

as for cost, it would be unwise for someone to just buy a used 8.8 and swap it in without rebuiilding it, so the cost of the detroit truetrac in the 7.5 would be about the same as the stock rebuilt 8.8 but the truetrac 7.5 would be stronger
