Hi Im looking for the stock exhaust heatshield, hold down nuts, and the stock exhaust from the cat back. I have a Dynomax cat back, and im done with the drone. Thanks in advance.

OK, so I bought a fully loaded/built PR44 from Northridge 4x4 about a year ago. Just a week ago, added in the Progrip brakes. Had a couple issues with clearance. Called Dynatrac, and even tho the shop is crazy busy getting ready and packing the shop up for 2 back to back shows, Tess was able...

Hi all. Looking for some thoughts around whether to build up my stock 2012 Rubicon axle by putting in an ARB and alloy axles or go with a PR60 loaded out. Cost is a big differentiator. Just curious as to tube strength of stock vs Dynatrac. Im not planning to go higher than 35s. Currently...

Mods, please move if this is posted in the wrong area.... Hi Jeepers. Do you have any recommendations for a good shop in So OC to do an install of an ARB? I got 2 quotes for the labor. 1 for 750 and 1 for 500. Seems kinda high. Already have the compressor in and functioning as I have an ARB...

Hello Does anyone know of or have a storage bag solution for the uppers on half doors for a 2012 2 door? Thanks in advance!

Has anyone had this happen to them before? I have a 2 door 2012 JK Rubi auto. I was at 4wd parts today, doing a ramp test on all 4 corners, to make sure I had good clearance and no interference of components after doing a lift. I ramped the front driver and passenger, no issues. I ramped the...

Im waiting for my PR44 to finish being built and shipped. I have a 2012 2 door jk rubi with 3.5 inches of lift. I have currie adj upper and lower control arms. As a start point, what should I set the lowers at? If you say stock length, thanks, but since I dont have any stock arms for...

New PR 44 Unl Questions Trigger pulled. David at Northridge 4x4 was extremely helpful in answering my questions and helping me get the right setup.

OK. Thanks! Its a steal of a deal for your exhaust kits anyway. This is one of the top mods Ive made on my rig.

Went with your and Dynomax's recommendation. ...the rockcrawler system. So easy to install. Truly, the hardest part was taking the oem system out. Wd40 is your friend with the rubber hangers, both for when you remove the old system and when you install the new. The sound is really bad azzz...

I just purchased a PN# 39524. Would this be applicable for that exhaust system?

Hey Dynomax, Thanks for the quick response and for your help on my shipment issue. Great product and super Customer Service. Very much appreciated!

Hello I WTB the following, and would request they not be beat to hell and back. Hopefully the joints are in great shape? 1. Factory OEM front track bar: 2007 to 2010 vintage 2. Factory OEM rear track bar: 2012 to current vintage I live in San Jose, CA 95125 if you want to calculate shipping...

Hello. Which exhaust system is recommended to replace the stock system.? The 2 I'm interested in are: 1 version is the rock krawler one. I believe there is another one that dumps out in front of the rear axle. Is there an advantage running 1 over the other? What's the rightpart number...

Hello. Can someone weigh in here: Is the coilover used in the bolt on kit for the front axle the same one used in the weld in DTD kit? IS the coil placement also relatively the same? Im asking this as I cannot afford to do a DTD right now, but perhaps I can do the weld in DTD bracket in the...

Hi! Pardon the dumb question... Looking for some advice on upgrading my rear stock JK Rubi axle I have a 2012 2 door Rubicon auto. Stock 4:10 gears and stock locker. Im going to be buying a PR44 Unl for the front (arb, 4:88, RCV, Reids, prosteers), and since Im doing that, would like to do...

Im planning out my next big thing. ..which is a PR44 Unl. On the Offroad evolution website, when you configure the axle, there is an upcharge for Extreme Duty. What is that option? I cannot tell from whats there. Thanks in advance.

Hi all. Ive been reading a lot, learning a lot. Have made some investments in my build that I really should have not done (Reids, RCVs) because the parts wont carry over to a new PR44 UNL. Hoping to recoup some cost if I can sell my current built axle. Heres where I want to go: 1. PR44...
