ARB Lockers
Hi All, I am exploring the possibility of installing an ARB lockers on either the front/rear or both axles. I currently have a limited slip in the rear axle. My ONLY reason to install an ARB ...

EG,
What tires are you running currently? If they are 19.5's, the sand running is out altogether. The rule of thumb is to have the tallest sidewall you can get for plenty of room to deflate. Any tire with an 80 pound max inflation is bound to be stiffer and less sand conducive. Another good 'sand friendly' item is wider wheels. They lay the sidewall out better on sand.
There is no rule of thumb when it comes to your specific low pressure running. This can only be determined by getting out in the soft stuff and seeing what works and what doesn't. With my present tire/wheel setup (see below), I run @ 28 pounds, F&R if doing soft, sandy roads for any length of time, like Easter Week in Anza. At that pressure, they don't get hot. When it gets to blow sand and dune running, I like to start @ 22 pounds and work down from there to an absolute minimum of 18 pounds rear, and 20 pounds front. Tires are made very tough now-o-days, and we've run @ 28 pounds in Death Valley for days on end without incident as long as it's not on pavement for more than 2 miles. This still all boils down to floatation, which changes over the landscape. The pillar of sand running is the ability to get your pressure back up in a reasonable amount of time.
Before you jump on the Tru-Trac, be sure to ascertain the spline count of the item and its application. I jumped on the T-T's and found they only fit on a 35 spline front Dana 60 axle, (not the 32 splines that I had from the factory) so I had to change to 35 spline axle shafts which had a few more complications after that and was the driving force that led me to upgrade the whole front end to Dana 70 spec with selectable Dana 70 hubs.
If you don't have selectable hubs there is a wee bit of steer drag when you go around corners in 2WD with the system trying to make both front tires roll at the same speed and pull slightly to center, as with too much caster angle.
If indeed the Tru-Tracs fit your appl. you would have the most transparent and usable upgrade for the smallest cashectomy. Here are the units for my Dana 70 front end and my '99 Jeep XJ Dana 30 HP front end. They have a lot fewer moving parts than many other lockers.
