Dynatrac ProRock 60
When my rear axle in my TJ blew back in 2017, I wasn't sure who I should have build me an axle. I was told by my boss and friends that Dynatrac made better axles for Jeep than currie. When I went to their shop the owner gave me a personal tour of the facility. The customer service is amazing and their axles are even better! I have had it for 3 years now and I have beaten the hell out of it and it takes it! I have a 1999 Jeep TJ with a Pro Rock 60 in the rear with an ARB air locker, 35 spline axle shafts, and explorer brake conversion discs sitting on 35 BFG mud terrains. This axle is the most solid part of my car. After being super pleased with their service and product, I bought a ProRock44 housing for the front to be built when the front blows!

Default Topic
When I purchased my YJ in 2013, one of the big selling points was that it had a high pinion ProRock 60 rear axle. The axle was installed in 2004 or so and is still going strong today! I have not had a single worry or issue with it in the back of the Jeep, definitely the best option out there! Oh, did I mention the ground clearance advantage? It has the same, if not better, ground clearance than your typical Dana 44, how cool is that???

Worth the Investment!!
I've had 4 trouble free years with a prorock 44 up front and just pulled the trigger on the prorock 60 rear axle.
Great fitment on both axles and outstanding quality....couldn't be happier with dynatrac's

Bulletproof with PR60
Top notch quality and extremely beefy. I had great experience with my PR44 so shortly after the front, I upgraded my rear with PR60. The Dynatrac Axles has transformed my truck and I'm 100% confident to go anywhere!

Very Very Satisfied Customer of my ProRock 60 with 4.88 gears! Glad to be a part of the Dynatrac Experience
Just Installed a Rear ProRock 60 on my 2015 JKU. I Kept bending the axel shafts on my stock axel. But all around the axel is just thicker metal, support of the spring mounts, pinion angle, did have to make custom brackets to support my teraflex falcon shocks. Hopefully by Christmas get front dynatrac axel. Very satisfied customer!

With a prorock 44 up front and prorock 60 in back, I transformed my JK into a bona fide rock crawler.
I upgraded my 2009 JK-X with a Prorock 44/60 combo and couldn't be happier with the investment. Now I have confidence to hit obstacles that I never would have attempted before. The 60 is pure beef.. from the thicker axle housing to the 35 spline shafts and even the big brake kit that I also put on... my rig is prepared for anything. Keep up tube great work Dynatrac!

Complete Peace of Mind when I'm 1000+ Miles from home
2014 AEV JKU with a 6.4L/392 Hemi V8...When traveling with my family and tons of expedition gear I really can't afford any issues with the rear axle assembly. It's a show stopper any way you look at it...

Favorite Details: ARB Air Locker, 35-Spline Axles, 3.125-inch axle tubes and more ground clearance than the OEM Factory Dana 44 (that was destroyed and ruined a five day vacation)

This is easily one of the smartest investments for a JK/JL owner. I plan to upgrade the front axle to a ProRock60 as well for 100% Confidence!

Quality product, worth the investment
I decided to replace the stock 44's on 06 LJ with a custom width 44/60 combo, 5:38 gears & ARB's, 1/2" tubes and Pro-steer balljoints and brake assemblies. 5 years later and lots of wheeling trips I always have a sense of confidence that my ProRocks will get me back home. I would highly recommend this product to anyone looking to upgrade their Jeep

Best investment ever
After blowing up 4 stock dana 44 ring and pinions, I upgraded to the pr60, I have a 2 door jk on 37s and I can wheel black and red trails at Rausch Creek in PA with my foot to the floor with confidence that I will be able to drive the Jeep 170 miles home.
