Lock-Right locker likes and dislikes

Yes, having a selectable locker would let you run open when you wanted to. The difference is a lunchbox locker can be had for a few hundred bucks, a selectable will be in the $800 to $1,000 range.

 

and one of those Detroits found a home in my rear axle

 

So Lock rights do not do well on snow and ice. So they must be fine on wet or dry pavement but will handle alittle different?

 

I never had a problem running my Detroit locker in the snow and ice. Maybe because I have a fast power steering box and I can compensate.

 

Another thing to think about here, where you going to find a selectable for a 27? Lock-Rite, Aussie Locker, or a Powerlock limited slip if you can find one are basically your options.

A Powerlock in my D27 and a Detroit in the rear served me well for a lot of years. Now I have a D30 with an ARB and a spool in the rear, soon to be an Ox in the D44. I want the option to run completely open when I want. Kinda come full circle, the best of both worlds.

 

The rear differential in my 3A is a 41. I have a Lockrite installed. Although I do drive it on the street, I do not have a top and thus I have no on street, snow experience with it. I have been in a few very uncomfortable positions with my 3A while descending wet hills while offroading. Same with damp off-camber hills. It seems that the rear end wants to come around in these situations. Usually around towards my left (drivers) side. I am talking about trails that are mud slicked, not deep mud holes. I have considered removing the rear lockrite because of this.

I have the pin removed from the transfer case that allows me to trail ride in 2wd, low range because my front differential has a lockrite also.

I must say that with the lockrite in the front also, it does climb. The increased capability of the 3A blew me away.

So, there are my pros and cons. Hope they help.

 

Had a PowerTrax locker in the front Dana 60 of my W200 Dodge crew-cab for about 2 weeks. Even with 6000+lbs, 147" wheelbase, a 440/auto, and the extra weight of a PTO winch on the front bumper it would head toward the ditch on dry pavement. Turns out if had read before buying, it is not recommended for a full-time 4wd front axle use. The factory rear Sure-Grip is dandy, don't leave home without it. Selectable would be the way to go in my case, just went back to open front as I still managed to bury it axle deep in the mud with all four churning. Now, just don't stop in the field when pulling the 24ft flatbed.
