    I know you aren't suspposed to tow with a locker. But, what is the weak link if I tow (say a car and trailer up to about 6000lbs) with a 14ff, detroit locker, np203, and a th350. Would u-joints give out, over heat the trans, or just excessive tire wear. If I can't tow with the locker I need to get a limited slip or an ARB and 14sf.

    Why can't you tow with a locker? I've never heard of it.

    It's crap. I've towed a 17' trailer loaded with 5000lbs of junk a bunch of times with my 1/2 ton with Lock Right. You can tow, drive on the street, drag race, all kinds of stuff with a locker....

    With a 14 bolt, you have absolutely NOTHING to worry about. Tow away, load that sucker down

    The only real problem is when you're towing in the mountains. If you're coming down a steep grade, using engine braking, and come into a curve, then when the locker disengages it transfers all of the engine braking to the inside wheel. The outer axle shaft gets completely disconnected from the drivetrain when a locker unlocks. It's sorta like hitting the turning brake for the wheel that's now doing all the engine braking. The truck wants to jump sideways towards the inside of the turn all of a sudden, while the momentum of the trailer makes the trailer want to go to the outside of the turn. If you're lucky, you'll just need clean undies... [​IMG] If you're not, well, in many places here in Colorado it's a long way down once you cross that white line at the side of the road! [​IMG]

    Ya, you can tow w/ a locker...my dad recently bought a 2002 Chevy 2500HD and it has a locker in the 14BFF and it hauls things like a dream...

    Your dads new truck doesn't have a real locker. GM's come with Eaton Gov-Locks. They have spider gears, so the axle shafts never get disconnected from the differential, like they do with a Detroit Locker, Lock Rite, etc. They behave VERY differently.

    Ya, my 85 Jimmy came with a "locking differential" from the factory too. It is a gov-lock. They are half l/s half locker from what I understand. What I know is they suck, only work half the time and explode when you step on the gas real hard. Mine did.

    My Chevy isn't broken, its just out of gas.
