One other thing the guys at Redneck ram will ask you what size tires you are running. If you are going to use a stock pump I would use a 1.5 ram. If you say you are running 40s they are going to want to send you a 1.75 ram. That IMHO is a bit too much ram for the stock pump. Im thinking that's where people get frustrated and end up getting the PSC pump and larger reservoir from them to accommodate that ram. If you stick with the 1.5 with stock pump even on 40s you will be fine and will not need a pump (if you properly bleed your system)

I wouldn't go bigger than 35s on a 44.

I have run 37s on my 2010 with the 3.8 engine for years. I have 5.13s. It is slow off the line, but fine off-road. I would not recommend 5.38s because the pinion gear is tiny and prone to failure. I won’t detail all the other mods you’ll want for 37s, but suffice it to say, they are expensive.

Thanks a lot. Here's the plan. 3.5 lift. Chromoly times 4. 5.13 gear down. "C" gusset front axle. Prob truss as well (later) . 37" Coopers, like their weight, look, pattern, and tread depth. Steering mod undecided. That should handle it, don't you think? Few others over time... I think that'll get it wheeling safe and tuff for now. See any ****** in the armor?

Consider getting more life out of the stock shafts and diverting the money to a big brake kit. With 37s you’ll appreciate the extra stopping power.

I don’t know what wheels you’re going with, but if you have stock wheels you’ll want spacers. Otherwise you’ll rub.

It all depends on how you wheel and if you are a technical driver or just like to mash the pedal down to get through stuff. I ran 35's, 37's and 40's on my D44's for years (C'd and trussed) and never had an issue (And yes I wheel it all the time). I went to a Fusion 4x4 D60 ($4k) rear only because I kept blasting the ring and pinion to pieces (5.38 is tiny on a D44, switched to 4.88) when I installed the 6.0L V8 Still running the front for the last 2 years on the D44 with no issues.

I also +1 on the Redneck ram and have had the 1.5" on my rig with 40's for the last 2 years without a single instance. Sorry but the PSC is not worth the extra money imo. You have your box ported and then have the same ram that psc sells without their sticker on it and hoses... wth do you think is so different for 2.5x more money?

Some people just like to spend a ton for no other reason then to brag about how much they spent

5.38 and 37's with the 3.8. Not great, but doable. Do the C's and truss now and better axles when you can. PSC hydro assist and ball joints too...

And yes, you will need a programmer, but anyone changing tire sizes should already have one.

I ran 37” Pitbulls on D44 with 5.38s for a few years without any problems. Depends on your driving habits.
