ARB Lockers

Thanks for all the responses. So far I am leaning on just an ARB up front and leaving the LSD in the rear.

But it leads me to another question:

Currently when I put the truck in 4WD one front wheel will drive...I don't know how to determine which of the two become a drive wheel, maybe someone can answer that.

If I had an ARB up front, when I put the truck in 4WD without engaging the ARB, I would get no front drive wheel action at all, unless I engage the ARB then I get both, correct?

The front differential is open so both axles get equal torque. First to slip will lose even more traction and just continue to spin. Clutch type limited slip does transfer some torque but once the clutches start to slip it will lose most of its function. Truetrac geared limited slip actually tightens up as some slippage starts to happen. The more slip the tighter it grips and the more torque it transfers. In normal driving it feels no different than an open differential.

Your ARB is an open differential until you lock it up. Then it acts as a solid axle with both wheels turning at the same speed in all conditions. This will cause a bit of binding stress in a turn and will tend to force the vehicle to go straight. Probably not a big deal on the sand.

I would recommend a Trutrac up front and either ARB or Truetrac for the rear. I would let the factory clutch limited slip go away.

BTW if you have ever considered a gear ratio change this is the time to do it. Must do both axles with a ratio change.
