i want to get a locker rear end for my 1992 dodge 3.9 v6 2wheel drive.what rear end will fitt and what can i do =)

 

Well what rear axle do you have now? If it's the 8 1/4 you can get a locker installed. If you have the 7 1/4 inch, you need to swap in an 8 1/4 or 9 1/4 inch and then install one. Lockers never came as factory equipment so you'll have to pay a shop to install it. But if you get a new rear axle, you must get one from a dakota or durango because they are the only trucks with our lug pattern.

 

or go cheap and easy. weld that bad boy up. **do not try this at home i am not responsible for the outcome and anger when your rear end explodes. lol***

 

LOL! Yes you can weld the spiders up. Check the FAQ2 if you do want to.

But what is the lockers main purpose. Dragstrip? Offroad? Or what?

 

its alittle of everything,my 240sx had a welded diff ate throw tires and turning was not that great lol,but i have middle of no where and i got stuck taking my sis to the bus stop bc i did not have a locker rear end,how do i find out what rear end i have?

I welded mine. really not good for city driving, but great for everything else

 

there is only one true rear locker, the rest are limited slip to different degrees. the air locker is the best i have studied. push a button and the rear locks 50/50 each side. unlock it and you got an open diff. why are you guys debating about lockers when you can have the best of both worlds.

 

summit sells one for the 8 1/4 for 315 mopar makes it a limmited slip

 

Why do you think air is best? You have to have an onboard compressor to run it! The air lockers themselves are expensive, then the compressor and lines and wires and everything else to run it are expensive. You'd be looking to spend at least $1500 per axle!!!

I personally think the lunchbox lockers like the powertrax no-slip are the best option. Cheap, easy to install, strong enough for most stuff any of us will be doing! Also I hear they are good about unlocking when they need to unlock. You'd spend about a 1/3 what you'd spend to get air.

Lol, I didn't realize there was a debate going on!
