I came across this at summit racing and I'm thinking about buying it for my truck. It has a 10.25 open rear and would like to change it to a posi rear.

Will this work?

Detroit lockers are for race track use.

Straight lines

Not everyday driving.

 

I have had a daily driver with a detroit locker in it. Great off road. Sometimes annoying on road. I lived up north then, and the locker caused some fishtailing in the snow. Also on wet roads. In my opinion, if you can live with those problems and need the extreme traction they offer, it's worth it.

 

I have the same traction problems in my F-350 2x4 (no traction). I get the "one wheel turns only" when in mud or snow. I was looking at having a trac-lok installed or a donor rear w/ Limited Slip.

 

I have powertrax in my dodge truck and I don't like it it only gives me posi when my tires are spinning. Thats why I went to summit and found the detroit locker for my truck a open rear is good for daily driving but I also plan to tow with my 250. I rather pay a little more $$$ for something I know that works.

 

Why don't you look into an ARB selectable locker? They have good road manners because it's a regular open diff, but with a flip of a switch, you can have a full locker.

 

Thanks I will.....

 

a detroit is 625 at most places and an arb is 830 and 220 for the compressor not really worth the extra400plus dollars for a rear application,least not to me. for the price of the arb you could buy the detroit,have it installed and take the ol' lady out for one hell of a fancy dinner

 

Welcome fatdan. the detroit locker is what I guess I'll get

 

The only bad thing about a Detroit Locker is if it engages in the snow and ice as your tootling down the road, it could catch you off guard and swap ends on you like surewhynot said. If your towing at the same time, that's bad mojo. A selectable locker is $$, but you basically have two diffs in one package. I think an Eaton electric locker is a little cheaper than an ARB. Just a thought.

 

I'll check again at summit again when I don't have 4 people screaming at me to get off the computer LOL.

 

The locker will work fine for off road and is ok for racing too. Although most racers prefer a spool due to their simplicity. The locker is a little scary in the snow and rain. With that said it it will be downright scary on ice. It is going to handle a lot differently (better and worse) than it did when it was open.

 

I installed Powertrax No-Slips in my 84 F150 4wd and my 95 GMC Jimmy 4wd. I noticed a bit more backlash in the drive train on my Ford than my GMC, that is to be expected because it has a manual transmission. Yes they are a bit squirrelly on snowy or wet roads... expecially the Ford because it has 33" mud tires on it. It's very easy to spin out going around snowy corners in the Jimmy, it is a shorter wheelbase vehicle which I am sure doesn't help matters. There are drawbacks to having a locking or even limited slip differentials in vehicles that are driven in inclimate weather and road conditions. The flip side is if you ever get into a situation where you have a tire with little or no traction, the one that has traction is the one that will get you out. I have a locking diff in the rear and a limited slip diff in the front of my 84 F150, it's a tank! I have gotten in and out of places that bigger trucks were getting stuck in... simply because they don't have the traction! If you can live with the drawbacks you will grow to love lockers, I have a locking differential in every vehicle I drive... and wouldn't have it any other way!

 

Luckily I live in a part of NC that only gets snow once every 10 years. And have plans to take my F250 south only that's one of the reason I picked on the locker set up I most likely will go with that. Thanks everyone for your input.

 

hey every one this is kinda of the subject but i got an 84 f150 w/ a 6 inch lift and 35s im wonderin if any body has had any luck welding there rearend???? i know its kinda redneck but im tierd of being open and dont have the cash for a locker or limited slip right now
