Looking to spend money on my trans&rear

[mar666.0]

I have a 04 6.0 4x4 i have a pinion seal leak in my axle so i figured i would just pony up and spend money on the the rear end,,,,,,any suggestions on what i can do to upgrade my rear end like gearing(stock 3.73) locker or anything that can beef it up a bit,,,,,also i wanna give my tranny some love Automatic 5R110W

A TruTrac for the rear is a common upgrade as well as the '08 rear diff cover. I run the '08 diff cover with Royal Purple giving my running temps of 137*F.

The tranny and gear upgrades depend on your current tire size and useage of the truck.

On 4x4's gearing mods need to be the same on both axles. Make sure gear ratios stay the same at front and rear.

I dont know what exactly you should get but here is what can be changed.

Fluids: Royal purple for the diffs. AMS makes some stuff for the transfercase.

Gears

Driveshafts

Tourq converter

Fly wheel

Billet shaft for the trans

Pand and diff covers to hold more fluid and cooling grooves

tire size is stock i dont think i will ever run more than 35s and maybe a leveling kit,,,,for the most part the truck tows some trailers never more 10k and plows,,, i eventually hope i dont have to tow anything anymore or plow
