i hate the binding feeling we get from our 4x4 system. i know we shoud not use it on dry pavement, but it you wait till you need it it may not roll far enough to engage. my question is if i install a lunch box locker will that allow for dry pavement travel? isnt that what they do? release when not need and lock when needed?

if so is there a preferred? detroit locker, tru trac....

thanks

 

I've never needed to roll for it to engage, at most shifting through neutral into reverse then back has done the trick. That said why not get an auto-locker for the rear and improve your capability when in 2wd and 4wd (I'm assuming you want this for off-road, if your truck is mainly a street rig I'd go for a good LSD instead assuming you're open diff currently).

 

never had to roll it or pop into neutral i just turn the *** and it engages sumtimes i even roll down the window to hear it... only time i'll go into netural and revrese is for 4lo thats it... and to get it out of 4lo just poped it into Neutral..

 

Your thread was titled lunch box lockers. It's always "engaged" technicaly. You cant shut it off or turn it on. When power is applied to the rear wheels, you get possitive engagement of both axles. A selectable locker you can turn on and off. Going from an open diff to lock with a flick of a switch, like an ARB. A lunch box locker can be used on the street, but takes some getting used to. Some lock and unlock rather harshly. I had a powertrax no slip in my Chryco 8 1/4 rear end. Worked great off road, but if there was snow or ice on the ground and you weren't in 4x4 and just rear wheel drive, that rear end would but you into a spin quicker than ****! A rear locker for a truck is the best thing you can do for offroad traction. And the binding is just something you have to live with. Should'nt be driving on dry pavement with it, but sometimes unavoidable with patchy snow.
