Dana 44 axles + Lift kit on a TJ

So, I wanna run 35's on my stock 2000 TJ, 5 speed. Yes I know it has to be lifted, next paragraph. I was told to re-gear my TJ, also I should swap out axles, get rid of the D30 & D35. Because I'm throwing $$$ away on gearing the 30 &35. SoDana 44's are what I need. Will just any D44 axle work? What gearing also? 4:10?

What all do I need to change? Transfer case? Transmission?

How much lift to run 35's? Should I bother with a body lift? Cheap fix? I was told I need a new drive shift if I go 4 or more inches?

Thanks everyone!

No reason to dump the D30. Just upgrade with chromoly axle shafts. Ditch the D35 in favor of a D44. 4.88 gears work best for 35s. Might as well install lockers while regearing.

You will also need a 4" suspension lift, 1" body lift, sye, cv shaft, upgraded steering and brakes. Don't go cheap on the lift. Make sure adjustable control arms are included.

Expect to spend in excess of 5k. Good luck.

Im on several of those Facebook Jeep pages, & I commented on a post where some people were chatting about axles & stuff. Some guy there said gearing my D30 & D35 are waste & to invest into D44's.

But will just any Dana 44 axle fit a TJ? Or should I find one from strictly a TJ?

Could I go with a 2 inch body? Or is 1 inch a lot easier?

The only D44s that are straight bolt in are from other TJs. Other options exist but require more work. There are other potentially interesting otions besides the D44 (e.g. HP30, 8.8 or go big)

While there are differing opinions, most here choose not to go above 1.25" for a BL.

You're correct, its an undesirable D44a.

Not a good swap candidate for the reasons you mentioned.

Also, its overpriced in my opinion. I had a WJ D44a for years that I recently sold for $100. I was very happy to see it go.

If you can find a take out rear Dana 44 out of a TJ for less than $800ish that would be a decent axle to buy, otherwise have a Ford 8.8 modified to fit your TJ. The TJ front D44 is a low pinion, and it's expensive. Better off would be an HPD30. Just as strong driving forwards as the LP44, with more ground clearance. They both use the same axles, steering, knuckles, u-joints etc.

The two axles that you mentioned do not use the same inner axle shafts...

I'm not 100% but the LPD44 uses a 30 spline inner shaft instead of the 27 spline. All of the outers including the U-joints should be the same. Is that more accurate? If so do you feel the 30 spline inners are enough to recommend a LPD44 over an HPD30?

Not if the inner axle shafts being used on the HPd30 are upgraded shafts...

There are many ways to fit 35" tires. The most common is a 1.25" body lift and 4" suspension lift. You can also use high line fenders, or metalcloak fenders and little to no lift.

Stock brakes suck with anything over a stock size tire. I don't even like them with 33's . A vanco big brake kit is one of the best investments you can make.

There are many ill informed people out there who think you need to trash the stock axles completely and swap in this, or that. 35's is the point you need to replace the rear d35c imo, but some choose to do a super 35 kit insted. They work well for many, but with my lead foot and v8 power it wasn't an option I cared to explore.

The dana 44 rear out of a tj, or lj will bolt right in , but the drive shaft may be to long since the dana 44 pinion sticks out further from the axle center line than the d35c.

The 95-01 ford explorer 8.8 rear is a very popular swap for the tj. It will need brackets welded on to bolt in, but many companies offer kits to do so. The 8.8 is cheap and they are abundant due to them being used in every 95-01 explorer. The dana 44 on the other hand was only an option in the tj and are hard to come by. The lj had a rear dana 44 as standard equipment, but the lj is a bit rarer in and of it's self.

The Rubicon also had the D44 rear axle as the standard axle...
