2016 JKU 75th Anniversary Edition
I was re-gearing our 2016 JKU from the lame 3.21 gear ratio to the 4.88 ratio. The Jeep had the TracLoc differential, which was ok, except that it had developed a popping sound when pulling from a dead stop. I took it back to the dealer who tore into it twice looking for broken worm gears. I seriously doubted the worm gear theory and asked them to check the diff. They did and said that everything looked good. I did some research on my own and discovered that the clutch type diffs could possibly need rebuilt after 35-40 thousand miles. Mine had right at 40k, so I decided that instead of spending money rebuilding a diff that would have to possibly be rebuilt again later down the road, I would swap to the Detroit TruTrac while I was in the process of the re-gear. I could not be happier! The sound has disappeared, in fact it is quieter than the TracLoc! Right now, I have about a 1000 miles on the swap and have nothing but praise for the Detroit TruTrac! If you are looking to improve the performance of your Jeep, you cannot go wrong with the TruTrac! And hey, while your in there slap some bigger gears in it. You’ll be glad you did. The little Pentastar 3.6 is a beast with the 4.88’s!

Install was easy enough. I’ve only driven on hardball and a little gravel so far, but it feels good so far. Making turns is quiet and smooth.
