ARB are s***, (not the s***z) simple as that.


I see a very few failures in ARB air lockers when installed by experienced people
-failures in early lockers were due to a design fault, ARB rectified that in later versions
-other failures are almost always due to poor installations by unknowing techs
-the seals do need maintenance from time to time depending on use
Lock-Rights, Aussies, and other lunch box units
-work okay, but have some annoying quirks
-cost effective
-not really that great in the front end
-installation quality can affect your experience
-most problems are with weak diff carriers such as found in the small Jeep axles and others that are made with small parts
Welded, Lincoln etc.
-shed metal and eat bearings and gear faces depending on how the welding was done
-really not a good idea in a front end
-only as strong as the stock "heat treated" carrier
-super cheap for super cheap people
-personally, I frown on these
Full carrier lockers such as the Detroit
-strong carrier
-generally much better than the lunch box units due to a stronger carrier and better engage/disengage camming
-smoother, usually nicer to drive with
E-lockers
-strong carrier and design
-work well if you respect the design parameters and coarse dog teeth
-would have to say they have a somewhat higher failure rate than ARBs related to the electrics/motor
-need to have full floaters
-slow to engage due to coarse dog teeth
-water intrusion, relay faults, motor faults, broken dog teeth all are hard on these
Cable lockers
-reliable, strong
-have to have full floater, need a longer spline on one axle shaft
-slow to engage due to coarse dog teeth not lining up
-must work within design parameters and respect the design limitations (as above by engaging them gently, then using them and not just beating on them before they're engaged - same goes with the E-locker)
-cables can get stiff if water gets into the housing
-mechanism can get stiff if water gets in
Take your pick, they all have issues if you don't install them right and abuse the product.
For the aftermarket, I really prefer the Air Lockers. I have been running these and installing them for just over 20 years now... they are a good product, with good product support.
