37s on stock lift

[Gladiator.916]

Hello everyone,

New to forums here. Just picked up my 2023 Jeep Gladiator Rubicon (Diesel). Reading around multiple different forums and getting mix answers about fitment of 37s in stock lift. Anyone running it, if so how is it?

Hello and welcome to the forum! Congratulations on the new diesel ! I have 2 diesel Jt's both lifted one 2.5 and one 3 inch I run 37's on both mine I did try my 37's on my stock Rubi but not my recommendations yes they can fit but they rub and kills you off road especially with the diesel I had the mopar lift installed made all the difference in the world and the diesel is a beast off road i own 5 Jeeps total and the diesel in my opinion is the best engine combination Jeep has ever had! I've owned 2 392's original Cj7 with a 401 your gonna love the diesel!! Merry Christmas

Did you regear the diesels you had or they do decent on stock gears?

I have stock 3.73 that all the diesels come with and theres no issues going down the hiway at 85 mph and off road is no issue my son has the very same Jeep Jt as mine we ordered 2 identical Gecko rubi diesels he runs 40's on his and regeared to a 4.63 gear and its almost to much gear for hiway driving

Perfect. Thank you for all the info again.

I came from the toyota world over to the jeep world. Had a 2004 toyota Tacoma double cab on 35s extremely under powered. Was regeared and superchargered.

I'm a used dealer I have 5 personal Jeeps had 30+ new tgeres not a better combination then the diesel I can run down the highway at 85 no problem with 37's tge torque is awesome! Funny my buddy is a Toyota guy he has a 17 Trd Tacoma he just bought a crashed 22 Jl and pulled the ecodiesel out and is swapping it into his Tacoma he hates going wheelin or riding with us and we have to wait on him. You'll be happy with the power couple things buy the 24 grille it helps cool it down upgrade the air filter there is an auxiliary radiator thats guys are using also I have no problem heating up unless I'm towing heavy and really push it

37's will fit but will rub with stock height. For wheeling, you will need a 2" lift. You don't have to regear with the diesel. It has more than enough torque to handle them. Your mileage will drop with the 37's too.

Mine with a 4" lift.
