ProRock 44™ Front Axle for Jeep JK

Product Code: ProRock 44 for JK
ProRock 44™ Front Axle for Jeep JK

* Required Fields



The Dynatrac ProRock 44™ front axle offers incredible strength and unmatched ground clearance. We engineered this ProRock 44 as a direct replacement housing for 2007-2018 Jeep Wrangler JK front axles, replacing the factory Dana 44, addressing the critical areas that fail when larger tires are installed and the vehicle is used regularly off-road.

The Dynatrac ProRock 44 offers more strength and features than competitors:

  • Patented ProRock shape delivers more ground clearance than a Dana 30
  • In fact, that’s the most ground clearance of any Dana 44-based axle
  • The strongest end forgings, made by Dynatrac in the USA
  • Rock-proof nodular-iron Dynatrac differential cover included
  • Heavy-duty 3.0-inch diameter axle tubes with .313-inch wall thickness
  • DOM (drawn-over mandrel) tubing
  • New upper suspension bushings already installed
  • Laser cut suspension brackets that are thicker and stronger than factory
  • Includes new replacement OE balljoints, already installed
  • Retains the Next-Gen JK 44 ring and pinion for more strength over earlier Dana 44 designs
  • Entire axle housing is manufactured in the USA
  • Exclusive Dynatrac no-fault, 12-month and unlimited-mileage warranty

When using the axle configurator on this page, you can choose a ProRock 44 housing. If you the ProRock 44 is for use in factory Rubicon, you will re-use the factory electric locker. For all others, choose a completely assembled ProRock 44 which will come with your choice of new differential or locker. If you choose an assembled ProRock 44 with a new differential or locker, the price includes the ring-and-pinion gearset, gear setup and install kit, yoke and the axle will come to you assembled. You will need to add the knuckles and brakes from your factory axle.


  • Using the the integrated ram-assist bracket on the ProRock 44 requires that you flip the drag link.. You can read details by clicking here.
  • The new ram assist/steering stabilizer bracket for the ProRock44 is not compatible with Reid Racing knuckles. If you wish to use Reid Racing knuckles, we can substitute our first-generation raised trackbar bracket which does not have the integrated ram assist/steering stabilizer mount. Please call 714-596-4461 for details.

One of the best upgrades
Hands down one of the best upgrades so far. It’s night and day compared to stock D44. Not only did I gain strength but the high pinion angle was a must after lifting a 2 door. The C’s are nearly twice as wide and gained almost an inch of clearance. Wish I would have just spent the money a along time ago. ProGrip with ProRock...up next is a ProRock 60!!!

PR44- The only Option
I have a 2008 JK. I had a stock D30F with 3.21 gears. After constantly worrying about it's durability, I finally bent the housing. Knowing 37" tires were the biggest I'd go, I decided upon the golden standard- the PR44. After 2k miles on the PR44- all I can say is that I should've done this MUCH sooner. I opted for the Ultimate 44 and I now have the Confidence to Explore any obstacle I choose. The axle is beefy, the high pinion, thicker and larger tubes, gigantic axle C's, and phenomenal housing clearance are just as advertised. Do yourself a favor. Choose once. Choose Dynatrac. You won't regret it.

When only the best will do
Purchased the ProRock44 this year and wish I would have done it sooner. When I had my Dana 30 I was always worried it would explode on the trail. Now I hit it hard and no issues. I got the 1/2 wall and it is rock solid. If you are on the fence, go with the best and never look back!

After cracking the Dana 30 ring gear it was time for an upgrade. Dynatrac is well known in the industry and I decided that would be one less thing I had to worry about breaking. The entire assembly is pure beef. Biggest benefit was it bolted right up. No welding brackets or anything. Great product and a killer upgrade.

I got the Dynatrac Prorock ultimate 44 package and all I can say is Beef !! I have it on my 2013 Jeep Jk on 37’s with rcv shafts they offer at Dynatrac. I know I can drive it up to any trail and have no problem driving it back home. I have confidence to go explore with no worries. I have beat on my axle time and time again and none of those rocks up in big bear phase it, nor the nodular diff cover as well I have scratched it dropped it on rocks and it has not failed ! It’s been 7 years and still going strong ! I am for sure buying it for my wife’s JKU !!! I can’t wait to get another Dynatrac Prorock 44!

Huge improvement over Stock D30 on Jeep JK Sport. steering, castor and pinion angle are so much better now. I have no regrets as I have progressively been getting more and more into technical trails. I needed to have the peace of mind to go anywhere and not have the front axle explode on me.

Unmatched strength
After 20,000 miles of cross country driving and some of the best trails in the country I couldn’t be happier with my pro rock housing and dynatrac ball joints. I run 40s with 300m RCVs and no concerns of a bent housing or broken balljoint. The extra clearance and correct trackbar mount location is icing on the cake .

Exceeded my expectations
I a JKUS. Few years ago my 35s were ending their useful life and 37s were on the horizon. Building my jeep to go wheeling out of state from Houston (not a trailer queen) I needed it built to take the abuse. I didn't shop around for options because a PR44 was always on my wish list. I bought the axle from a Texas vendor. My axle has 5.13 gears and an Ox, cable actuated locker. I have beat my axle up in Colorado and Moab. Zero issues. I love this axle and the confidence to explore!

After bending my front sleeved and gusseted Dana 44 in my’09 jku I bought the prorock 44 unlimited. When it arrived I knew it was the right decision. It was pure beef. It works great and has never given me any problems. I can always depend on it. It has held up to my heavy armored jku on 40’s without hesitation.

After bending my front axle housing I was looking for a replacement that I don't have to worry again.

ProRock44 Gets it done!
Purchased the ProRock44 for my front axle and a ProRock60 for my rear. Confidence to Explore is spot on! I used to be worried about breaking my Dana 30 front and didn't have real confidence in the Dana 44 rear but with this upgrade I am so much more at peace hitting the trails and rocks a long ways from home and often out in the middle of know where. Off-roading has it's risks and there is always potential for something to break but I am no longer worried about my axles! Best upgrade I did to my rig!!!

Confidence to explore, nothing less
I had purchased my prorock 44 in the spring to prepare for a big west trip I take every year. After having been the previous year on a dana 30 and 37s, I wasn’t too excited to feel the nervousness of being stranded in the remote desert. Fast forward we spent a week in Moab last week and the axle performed nothing short of flawless. I was able to go anywhere I could possibly want and not think twice, even running 38s. The prorock 44 is the best 44 series axle on the market and at the price point, quality, and made in the USA guarantee, you CAN NOT beat it.

Upgrade your rig to this American made perfection
For years I searched and planned for a way to upgrade the stock Dana 30 front axle in my 1988 Jeep Cherokee. This is by far not only the best value but the strongest option on the market. The most important feature to me is that it is %100 American made. I was able to call Dynatrac and spoke with a knowledgeable staff member who walked me through having a totally custom axle built for my rig under my specifications. My Prorock 44 handles all terrains without hesitation and truly give me the confidence to explore.

JK PR44U axle
I have had the PR44U for my JK for 3 years now and it has performed flawlessly. I have beat on it at Moab, The Rubicon, John Bull, and many more and have never had an issue. I am a lifelong fan of Dynatrac, not only for their products, but for their service as well. I was at TDS and lost a bolt in one of my control arms. Jim from Dynatrac stopped what he was doing, while working the sales booth, and located a bolt in their spare parts. Not only did he not even know (or care) if I had a Dynatrac axle, but gave me the bolt for free.

True confidence to explore
After breaking three factory axles we figured something had to change. Sure factory swaps are cheap. But the continue to break. We purchased the ProRock44 because of all the positive comments folks said about it. We spoke to a customer service rep at DynaTrac and that conversation just sealed the deal. It’s been just under two years and many adventures later that we continue to smile as we wheel down the trail. Thank you DynaTrac for offering the “Confidence To Explore”.

Incredible Upgrade to the stock D44/D30 on the Wrangler
The stock front axle on any Wrangler will sooner or later be damaged or worn out if you do any kind of off-roading with bigger than stock tires, Chrysler did not build the Dana 30 / 44 to hold up to real offroading and trail abuse.

Once you realize this there are 3 options for you to consider:

1) Keep wheeling stock axle and risk busting/breaking it in the middle of the trail and do potential damage to the entire driveline and have a long down-time

2) Reinforcing the stock axles through new sleeves, shafts, gussets, truss, etc - This a ton of custom fab work and it still does not fix a lot of the issues with the design of stock axles such as the extremely thin axles tubes, stock C's and clearance.

3) Replace the axles with a heavy-duty ProRock 44 axle from Dynatrac, which I chose.

When I had the realization that the stock D30 needed to be replaced I contacted Dynatrac and the guys there did an amazing job at completely taking every single detail and building the perfect extreme duty axle I was looking for.

I chose to go with pretty much all the upgrades (do it once and call it a day) with Dynatrac Axleshafts, Ball Joints, 1/2in Tubes, E Locker, etc.

Once I received the axles I was blown away how awesome it came out. Every single detail was perfectly built and the whole axle was a plug-and-play replacement for my stock.

On the trail, the ProRock 44 is a game-changer. Not only do I have more clearance, but the axle is so beefy and rugged that I no longer worry about hitting it again rocks, boulder, trees, etc. The performance and quality is incredible and I will 100% come back for the rear ProRock 60

Love my Prorock 44
I upgraded my stock Rubicon 44 to a Prorock 44 we jumping to 37" tire. I ordered it with 1/2" wall tubes for the confidence of now bending or breaking. The swap was easy and it allowed me to keep my stock locker when I had it geared. The axle has been on a ton of trips with me and I never worry about having any issues with it.
