Getting ready to lock up my Sterling 10.25 with 42" IROK's, but the full Detroit is a tad pricy for my poor self. I was going to weld it, but have never welded a diff before and am kind of leary of doing it in the housing.

But, I did see you can get a Lockright now for the Sterling 10.25, way cheaper than the Detroit. Anyone using it? If so how is it doing back there?

Pull the diff out and weld it.

I've had a lockright in my 10.25 for five years running heavy 38" tires (150 lbs) and it's held up fine. It's pretty loose now but I'm sure replacing the worn springs with new springs would tighten it up. I wouldn't have any problems recommending a lockright for the 10.25

i have one in my 10.25. i run 36's and a pretty well built 351. no problems in over 15k miles.
got it used from a guy who had about 10k miles on it. similar truck. looked like it was brand new. :)

I'm planning to swap a 10.25 with a 3.08 gear into a 72 Ford diesel tow rig. I have a 92 with an open 3.55. I'd like to improve on an open but not with a typical limited slip. I don't believe there are e-lockers available and I'm guessing there may never be. I have a lockrite in a front D60, but haven't used it much. The truck has engine driven compressed air already, but I don't think I'm interested in the cost or pneumatic function of an ARB for this application.

What is your opinion about using one for a tow rig on dry pavement? What is the operational difference between your 'worn' springs and how it was when it was new? Do you ever drive on the street?

I plan on taking the lockright out of my wheeling rig and putting it in my tow rig. My wheeling rig used to be my daily driver, put prob close to 30k miles on the lockright before the rig and axle was retired.

As for the worn vs new difference, I've had the locker unlock a couple times under extreme torque load- one wheel on very solid traction and other wheel in air with truck encountering a lot of forward/reverse resistance.

What do you expect operationally with it in your tow rig? I've never towed with a locker. I have a Detroit in a 14 bolt in my 4wd rig, and it seems doable, but towing a trailer with one is a different story.

I've heard a lockrite tends to be 'tighter' than a Detroit, but I'm just not familiar enough with them to compare their characteristics, not to mention on the pavement. Can you or anyone compare the operation of a Detroit and a Lockrite in a rearend on pavement?

I don't expect much of a difference in handling. It'll probably be less noticable from when it was in the Bronco. It's going from a 105" wheelbase to a 168" wheelbase so the effects are minimized. I'm sure I'll still get some tire scrub on the sharp inside corners but other than that, I doubt it'll bother me too much.

Had mine lockright? the "powertrax" is what I have, no problems so far, just know that you cannot put one in a limited slip carrier,and I don't believe they make one special for the LS carrier either. I learned this the hardway.


But, I would not tow anything with a constant locker. especially not when it gets slick out.

I had a detroit "quicklok" before, and that would open up a lot more, and crash back in around turns

My good friend has a Lock Rite in the rear of his 03 F350, CC, DRW, 4x4, PSD. He tows a 35' enclosed car hauler, about 100k on the truck and I will bet 80% of that is with the Lock Rite no problems at all with or without the trailer, regardless of weather too. I only wish my truck had an open diff, I would have one too.
It is his truck that is used in many of the Autometer magazine advertisements, and brochures doing a burnout in a monochrome red CC, dually.

I have a Lockright in a 14SF on my Z71. I use the Z71 for a tow rig for my 73 Bronco and have not had any problems. You will just have to get used to the clicking when they are new but they will quite down alot after they are broke in.

I've seen this debated on other forums. Most seem not to mind a locker in a tow rig. I've seen mention of broken axles 'caused' by lockers in rigs towing heavy trailer bead mounted hitches. It seems in most cases it's just fine. I may throw one in with my current 3.55 gear, and see if I like it. When I go 3.08, I'll decide to leave it open or install the locker.
