Dana 44 Dynatrac Prorock Diff Cover

How much bump stop extension?

At the time of the picture, none, since we were cycling for clearances. The Rocksport shocks have a 16.2” collapsed length.

Those shocks need at least 3" of bump stop extension, so we know that MC will clear with that much extension. It would be interesting to know when or if the track bar hits without the shocks in place.
 
Pardon my ignorance here, but are T & J Performance and Barnett the same company or does T & J Performance make the diff cover for Barnett?

Neither company appears to have a working website.

Pretty sure they are the same company or Barnett is now T & J Performance. Not sure whats going on with their website, but it's been like that for months.

T&J was the first to introduce that cover, that's where I got my first one 13-14 years ago. So far as I know, T&J went out of business years ago and their cover design was somehow acquired by Barnett. I'm now running a Barnett, it's a great cover... especially for the front differential where its design won't interfere with the steering system. Currie also carries them.

Back in may I somehow accessed T & J Performances website on a day it was working and ordered my cover. I got a bit nervous when I couldn't access the site the next day and more so when I didn't get a confirmation email yet money was taken out of my papal. I called up the shop in southern california and talked with a salesman. Guy couldn't have been nicer and told me that they make them to order. Mine took a bit longer since they were waiting on a shipment of covers to come in before they could weld on the additional armor.

If I was to do it again I would start by calling the shop directly and avoiding the website entirely.

I just spoke with a super nice guy named Mike from T&J. They are making the covers that Currie sells on their site. He is currently rebuilding his own website, and it should be up soon.

The price has gone up to $159 plus shipping, but they have a couple in stock and ready to ship.

SO T&J makes them for Currie, and Currie marks them up that much? I'm seeing $199 at Currie and you are reporting $159 from T&J?

You can find the Currie branded covers for less. I paid $132 for a Dana 30 cover @ summitracing.com and $132 for a Dana 44 cover from Jegs.com a couple weeks ago. Though the price seems to have gone back up since i purchased mine.

That flat design has been proven to be bad news for gear lube circulation. The ring gear slews the gear lube against that flat area where it just splashes and actually gets hotter. The smooth curved design covers keep the gear lube moving smoothly up & toward the back to give the pinion bearings adequate lubrication. There are a few videos I saw in this subject that were eye-opening. Good gear lube flow and coverage is why the factory cover faces are smoothly curved.
Gale Banks on YouTube has the videos you are looking for.

Ive got the PS cover that came with an axle purchase, so I decided to give it a shot. Full bump with 2" of bumpstop on a 4" lift. Plenty of room. I do plan on getting a barnett/currie at some pont.
