Good stuff - just put in GrizzlysBought our 08 JKU with beefy ProRocks already under it (44 front, semi-60 rear), and 37s. Front has RCV 30-spline shafts, Spyntec free-spin hubs (D30/44), and Warn lockouts (Warn 60165, now discontinued - now have to use a 19-spline Warn 20990 and a 300M 30-spline replacement gear from RCV).
Don't like selectable lockers so we just replaced both ARBs with Grizzlys. So long as the front is 30-spline Grizzlys (or Detroits) will fit (no 35-spline Grizzly). The carrier bearings are different - you'll need #25590 (bearing), #25523 (race) with the smaller i.d. to fit the Grizzlys (and presumably Detroits).Posted on

One of the best upgradesHands 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 OptionI 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 doPurchased 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!

Default TopicAfter 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.

Default TopicI 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!
