Ive always been told to pull in 4 low, the reason behind it is that they claim it puts too much stress on the drivetrain in 4 high, and 4 low will get ya more bottom end pull too. -

it depends on what kind of truck you got.......if its a stock truck......low side/low gear......if you got a dedicated truck or a powerful truck you can run the high side or low side and depending on what gear in the tranny you use.......it will speed up or slow down your tires.......some guys run high side 2nd or low side 3rd depending on tracks.....i know some guys running low side 4th if they are on the right track and the truck can make the power....... -

Great advice, I have a few upgrades to do yet before I even attempt it with my 03 GMC, like Tie rod sleeves, are there any better than Cognito, or would they be the best to go with? -

take your torsion bar bolts completely out if you got small enough tires........on the tie rods....no matter what company you go with.....make sure you get extra adjuster nuts......cause you will break or bend the aftermarket tie rod at the exposed threads.......it happens everytime.......build you a set of traction bars and bumpstops too.... -

if you love your tranny stay on the low side unless the track is extremely muddy or loose sand type. i run 4th-low on 90% of tracks with good clay, when its loose soil or muddy and i know im just gonna blow the tires off, go with 2nd high range for a tad more wheel speed and you know the traction is not there to bust the drivetrain.
when you run in low range (dodge has a 2.72:1 reduction ratio in the tcase) so that puts 2.72 times less tq on the tranny. i dunno how the ZF-6 is strength wise but i know there are more dodges that have grenaded nv5600's and G56's running 2nd gear high range vs. 4th gear low range due to this simple principle of tq reduction. -

Oh and you are lucky to have a 2.72:1... Us 1st gen pullers have to fight a 1.9:1 TC.  -

Cognito is the only place to get pitman/idler arm braces. For the tierods you can get sleeve or HD tierods. There are several places that you can get either. Don't drop the tbars all the way you want to drop them so the CVs are flat. Do this with your truck weighted down if your running extra weight. Before you back out the adjustment bolts get the front of the truck off the ground lifting it by the frame to unload the tbars a little more. Several guys just clamp the springs works kind of like a poor mans traction bar. Get some 3" ubolts that are flat not rounded and a piece of flat stock with 2 hole drilled in it for the bolts. Or 2 pices of flat stock with holes and 2 bolts. The idea it to make a clamp and use it to compress the springs down to the overloads in front and behind of the axle, so you need 4 clamps total. -
