Outer Limits 4x4 Board

As the title says what mods have people found is good to do

background:

its in a truggy running a v6comm motor with 4.3 atlas bolted to it the truck will be 1700-1800 kgs i think. Has 5.29 diffs

so your thoughts??

Deeper pan and decent cooler i wouldn't think the V6 will put much strain on it.
If your going to rebuild it its worth getting extra clutch in the forward pack and replace the thrust's with roller bearings-(optional) Also look at the plantery they wear on the trust side from the gears. There is a 6 gear option available. A stage 2 or 3 shift kit would also be good. I use TQF trans fluid it has more bite.
