Currie vs Terraflex vs G2 D-44 Front Axle?

Am considering replacing my stock JKUR Rubicon D-44 front axle with one of the above aftermarket axle housings for the added "C" strenght, tube strength and added caster (4" lift). I plan to keep the stock E-locker setup and will re-gear when I change out the axle.

The G2 is the least expensive, the Currie next and the Terraflex the most, but what are the little things that will make a difference in the long run? I would like to stay with parts that are readilly available, i.e. seals, diff covers, etc.

What else should I be considering and are there personal experiences with each? I am running Toyo 35's now, with consideration of upgrading to 37's.

Thanks.

If you plan to stay with 35-37's why not just beef up your 44 now?
Can't help you with the aftermarket axles I never looked into them. Just picking your brain, if you don't plan on going above 37's I'd personally spend money else where

I think I'd like the extra caster built into the aftermarket items. And, if I'm gonna spend a few hundred adding bracing to my stocker, by the time I sell the stocker I think I will be within a few hundred of the aftermarket - especially if I do the gears at the same time.

Beefed up as much as you can, the stock Rubicon Dana 44 is still really just a Dana 30 with a D44 center section and it will be weaker than any of the aftermarket axles by a long shot.

With 37's, you can beef up the factory D44 and wheel it for a while. And then replace it because the reinforcement wasn't enough. Then you pay for a new axle.

Or you can build a quality aftermarket axle in the first place and save yourself all that money in the long run.

I wouldn't put any $$$ into a stock axle. I had mine truss'd gusset'd to the gills and I still bent it on 37's.

I ended up replacing it with a Dynatrac pro rock 44, even being a 44 this axle is MASSIVE compared to the stocker.

From those 3 you listed I would do a currie since they've been building axles a zillion times longer than the others.

A correct axle housing is more than just pinion and caster angles. It's the geometry for spring pads, track bar bracket, control arm & shock tabs, etc.

So the axle housing you buy should have geometry for ever piece, that reflects your specific "normal" ride height after lift.
If they will build it for you based on those numbers, then there will be no compromises to longevity of all the suspension and steering components.

I've always built axles housings to match the vehicle. When at EJS this year, I talked to the guys at the Currie rig. They said, they'd build to my geometry specs at no additional charge. Not sure if that is industry standard, a show special, or just an acknowledgement for those in the "know" kind of thing.

I haven't talked to any of the other mfgs yet. For the price, if they will do that, I'd rather just buy and leave the welding box closed. It's a lot of painstaking work to get it right.

I'm becoming a huge fan of this whole "bought not built" concept.

Good luck with your decision.

I am in talks with a vendor For a G2 Core44 built for 4" lift. Looks like a real quality piece...

My opinion on this is buy it pre built with gears locker and axles, all set up roll it under and bolt ER up. In the end parts plus labor of building your D44 will be about the same.

I think most of the people on here saying "just build up your stock 44" have never had the chance to compare a stock 44 to a Dynatrac, Currie, or Teraflex 44 side by side. Everything about the aftermarket axle is much stronger than the stock 44, and gusseting or trussing a stock 44 will not narrow the gap in strength appreciably. You'll still be left with an inferior axle.

I'm happy with my Dynatrac axles, although I moved up to 60s on my Jeep.

So, how many of you who upgraded sold their stock axles and what was the going rate? That may make a difference if I go parts or full built....

Upgrade & sold stock axles here. Probably a rung down the ladder from what you're talking about.. but might be useful information. .

I bought a set of brand new Rubicon axles for $3500
I had 4WP do mine with gussets, sleeves and Synergy ball joints. Total bill was in the ballpark of $800. That's in central Indiana where nobody does this, so my guess in AZ it might be less. So $4300 in 2 new axles and the front reinforced enough for my needs. Sold my stock Sport axles (3.73 w LSD) for $1000. Probably could've got more, but I had 4 calls from a CL listing in the first 2 days. Probably didn't ask enough... oh well they're outta my garage.

So I spent $3300 and my labor to swap. For my efforts I gained 4.10 gears, e lockers and a reinforced D44 in the front. From what I found in my area that was pretty close to what a re gear and lockers would've cost on my stock axles and I still would've had the D30 with a smaller ring & pinion, so I think I did the right thing.

I did look into buying the Dynatrac, Tera44, and the G2 To do that I was well into the $5K range for a built front axle and still would've been regearing and adding a locker to the rear axle. Probably would've seen a $7500 bill easy, if I'd gone that route. I couldn't justify the expense for my needs.

I think you have to be honest with yourself about what your true needs are. If I was really a hardcore wheeler, then I might be better off to spend $7500 up front and be done. But I highly doubt that I'm ever going to break what I have now, so anything more would be overkill... and wasted money.

Vendors are gonna push whatever they sell, or make the most $$$ on.

And I'm pretty sure the G2's are made by currie, just with a cheaper price point compared to the "currie 44"

You get what you pay for, and axles is not something I'd wanna cheap out on if I'm spending the $$$ I want something that has a good reputation with quality parts.

Great question... I gave mine to the scrap guy.

It doesn't take much to tweak a stock d44.

I'm not positive, but I think the G2 is ProComp. The 4WP store in Indianapolis told me something to that effect... It could still be made by Currie, for ProComp dunno

Currie housings with G2 internals... God I hope there not Assembled by the asshats at 4wp!!

They can't mount a set of tires right, let alone think of building an axle.

Depends on the store you go to and the mechanic you get when you're there.

So true. I was never impressed with 4WP here, but frankly there really aren't any other choices around here. In general, I always felt the guys behind the counter were a little dense... but I was very impressed with the guy who worked on my axle. YMMV

Yeah, their bread and butter is putting lift kits on relatively new vehicles and mounting tires. They usually have someone who is decent at doing gears. But some of the guys they hire turn out to be not much more skilled than the average grunt at a Discount Tire.

It helps to get in good with the manager (like help him build his tube buggy) so you can know which tech to work with when you need a hand with something.

G2 axles were initially made by Currie with set 10 bearings and thinner wall tubes. G2 took some of those axles and reverse engineered them. They are now using their own center section made for them. G2 assembles everything from there.

Dynatrac, Currie and Teraflex are better options than a G2 by far (maybe not Core44; haven't looked at that one). All of them have options for thicker walled tubes and geometry set up for your height rig. You can get raised TB brackets and Reid knuckles as well.

Here is a TERA44 offer of mine.
Dynatrac Pro Rock 44 (Free Shipping). I also sell Currie's line up and G2. Ruffstuff makes great bare housings to build yourself as well.

Have a blessed and prosperous day!

Another vote for the TF 44. If you go with the Rubicon version everything (lockers, gears, and inner axles) will swap right over. Mine cost 2k and had new ball joints included. The thickness of the C's, tubes, control arm skids, and raised trackbar bracket plus the 3+ caster correction sold me.

We have always had the most success with the ProRock 44's from Dynatrac. If you are looking to swap your internals they have a housing that is set up for that and includes the Unlimited Geometry for 2.6-6" of lift. The tubes are 3" OD, .5" wall and the C's are massive. Dynatrac JK Rubicon 2007-15, ProRock 44 Unlimited Package - JK44-1X3010-G-KIT It does come as a bare housing but we can press in balljoints for you if you want. PM me for more info!

First, we’d like to point out that Dynatrac was the first company to offer a bolt-in replacement axle for the Jeep Wrangler with our ProRock 44. And we’re also proud to have more ProRock 44 axles under Wranglers today than all of our competitors combined.

What sets our ProRock 44 apart is the engineering, materials used, and how the ProRock 44 is 100% made in the USA. Our patented ProRock design gives it the best ground clearance in the industry – even more ground clearance than a stock Dana 30. We engineered it to be the strongest 44-based housing with the least deflection. We also make the strongest C forgings in the business. Our materials are all US-sourced and our manufacturing process has tight quality-control. Dynatrac also have the best warranty in the business.

You can read more about the ProRock 44 here: ProRock 44â„¢.

Our ProRock 44 for the JK starts at $2,159. You said you want the added caster and pinion angle because of your 4-inch lift, which would make our ProRock Unlimited the perfect solution, and it starts at $2,347. Our housings include the Dynatrac diff cover, new suspension bushings and ball joints. Two very popular upgrades are our ½-inch wall thickness axle tubes (although with your lift and tires, we think you would be fine with our standard 3-inch diameter, 0.313-inch wall thickness tubes) and our rebuildable Dynatrac Heavy Duty Ball joints.

Although the ProRock 44 is meant as an upgrade axle housing that you swap your differential and axleshafts into, our dealers or us can build it with variety of differentials, gears and shafts installed.
Unlimited geometry??? Very curios what this means as I too will be looking into a swap out front end and I like the Made in USA thing...

It means pinion/caster is corrected for lifted JK's.

I love my Dynatrac ProRocks and would pick Dynatrac again over the others, but from those 3 you listed I would choose Currie.
