Locking Differential For 2WD?

[DnStClr]

 I've been thinking about a locker for my 2wd. It has an open differential. I've spent some time looking at lockers, and most threads I've read advise against a locker and seem to prefer a limited slip. Is this true, or is it possible to get an automatic locker with good road manners that's quiet? This isn't for off-roading. Just for a daily driver during winter and gettting around the farm in the wet weather.

From what I have gathered which I am going to install in my C10 when I find one the Gov-loc is suitable for stock use that is not going to be beat on.  I just want 2 wheels with traction in snow and mud when it is needed.  I won't be dropping the clutch around corners so a stock set up should work fine for my needs.  I am sure you will get others that will disagree.

I like the gov lock idea over a true locker.

A true locker will have some pretty bad manners on wet, snowy, or icy roads.

X2 and they aren't quiet.  The POPPING and BANG will cramp your chest the first few times you hear it.  They gradually loosen up, but over a period of years.

Put a lock right locker in and you'll be happy it's also very easy and cost effective. I've personally run LS and lockers and prefer the locker especially in a 2wd. Each different manufacture of limit slips have a different way that the internals work. The G80 uses friction disks that actually (even if it's just a little) is wearing out as it's being used.

i dont know why but im a fan of Detroit lockers myself. had on in my 79 in the mud or if i was slipping it was locked but on the streets i didnt have a problem unless i wanted one

[pholliday1]

I know you like them, cause they work great and there bulletproof it's a great combination

You need this:

You will also need an installation kit and LSD additive.

I would certainly choose an LSD over a locker. What ratio do you have back there? Good time to upgrade the ring and pinion too.

[DnStClr]

hi Vile. Actually, I'm leaning toward the Detroit Trutrac - But I see the Auburn costs less.The gearing is a 3.08:1. Definitely needs an upgrade- 3.73:1 ?

[VileZambonie]

You have a 700R4? Do a lot of highway driving? What size tires are you running?

[DnStClr]

Yes-700R4, tires are 31x10.5x15 Almost all totally highway and backroads driving.

[VileZambonie]

3.55:1 or 3.73:1 depending on how fast you drive on the highway.

ok. I'm armed with some pretty good info now. All I have to do is get the truck away from my grandaughter. She's been driving it to school this winter.

Can you after completion of the Installion of the limit slip report back the approx cost of going that route? It may help others in the future with their decision. I'm guessing after the cost of new bearings setup costs and the cost of the new differential it's going to be pretty costly. Hopefully you have some close friends with lots of skills! Good luck Don

[DnStClr]

Yeah I hear what you're saying about costs. I have preliminary costs so far.-
The LSD-                         @$400 for Auburn unit, or $435 for Detroit/Eaton unit.
Installation Kit-                @$100
Richmond ring & Pinion     @$212
Install kit-                        @$117
GL6 gear Lube-   2 qts       @$46
                                     _______ 
                                       $910         
                                          86  tax
                                         ___?  shipping     so it's over $1000 before labor.
