Eaton 913A589 Detroit Truetrac Rear 30 Spline Differential for Dana 44

For anyone questioning if this fits a 2007-2018 JK non-Rubicon dana44 then wonder no longer, it fits. Gear sets 4:11 and numerically higher. It’s also drilled for large and small ring gear bolts. Very happy with the performance of my Trutrac!

Great fit for a Dana 44 rear axle 30 spline for my 2001 Jeep TJ

Based on others' experience, this is a good product, but verify fitment. Verify fitment. Verify fitment. Did I mention you should verify fitment. I called four different outfitters, told em what I had, and this is the one I "needed". The holes have to be drilled out for me to "need" it. Drilling, hardened, steel. Drilling something you paid almost $500 for. Really?

I had the trutrac installed on my 98 Wrangler. It has worked great. Been on some more difficult trails and it has performed better than any of the clutch type limited slip that I have had. I get good traction even on loose surfaces and don't have to worry about breaking an axle when I get on rocky terrain. Considering one on the front instead of lockers. The problem of some grip required for power transfer is easily overcome by applying some brake pressure.

Hands down this unit far exceeds the factory. Still going strong did have doubts at first but now I have none2020 update. My friend said thier still going strong. No issues2022 update. Still all good she said still doing well but a little clunkier than it used to be
