I never understood why 3.73s were never a factory option with the JL like it was for the JK. Perfect for 33s, okay with 35s.Unfortunately, FCA totally f*cked up making the standard gearing 3.45. That gearing is absolutely worthless with tires larger than 33s.
Indeed. Coming from several JKs with 3.73 and 4.10 gearing, it never occurred to me that Iād be scrambling to regear my JL like I am now.I never understood why 3.73s were never a factory option with the JL like it was for the JK. Perfect for 33s, okay with 35s.
Obvious hindsight here, but that's one of the main reasons I purchased a Diesel Wrangler with the Tow Package. Gets you M210 fronts, and M220 Rears, and the 3.73 gearing, all told you can run 37's without having to regear. A little more money up front, to save you the trouble later.One thing Iām learning the hard way:

I think youāre putting way too much faith in re-gearing. The fact is, a JL with 3.21ās still has a lower 1st gear drive ratio than even a JK rubicon with 4.10ās (3.59x4.10=14.719, 4.71x3.21=15.12 for the JL). 3.21ās are high for 35ās, but they didnāt sell the JL like that and the transmission still makes them adequate. Jeep clearly suggests 4.56ās for 35ās by the way they built the XR package, but I wouldnāt say thatās the only option thanks to the massive gear spread enabled by the 8 speed. Gearing being right was much more critical in a JK in my experience. I hope the regear has the results youāre looking for, but I canāt see it doing anything for fuel economy on the highway. The engine sees load and rpm, it doesnāt know if you are in 6th gear with 3.21ās or 8th gear with 4.88ās, same effective drive ratio, same rpm, same load.Indeed.

Omg Iām TOTALLY giving the kiddos powdered doughnuts next time the tops down! Ha!Similar lesson... I stopped at the doughnut shop drive through with the kids on the way home from the lake. It was already dark, and the top was down. The next morning when I got in the Jeep to go to work it was COVERED in powdered sugar.
Lesson learned: donāt let your kids eat powdered doughnuts with the top down on the highway.
He canāt help youā¦. Itās the āother dudeā that controls your wallet.I've learned that after EVERY wheeling trip I identify at least two or three things I NEED (not want, please!) to get. This weekend I'm headed to WinterJam in Sand Hollow. There are venders there. Lord help me.
Yeah I feel that, my friends made fun of me when I ordered my lift kit and bumpers before even having my JLU and then regearing it with 1000 miles on it...I've learned that buying a $50,000 vehicle and then disassembling parts of it makes other people cringe
