You don’t hve to worry about any overheating. I like 5.13’s even with 35’s. I’d say go 4.88 for a bit more mpg but 5.13 for better crawling on the rocks.That’s not much different. And you have 5:14? Right now I shift at 14 mph just under 3000.
The off road shop suggested 4.88 for me. I don’t want to be overheated. Will never go above 35s.
Hey Man,Just installed 37s and ESS fault went away. Killed two birds with one mod...well that and the Rock Krawler 2.5 X-Factor lift.
IMO, 4.88 gears match PERFECTLY with 37s (measured 36" installed) on my 6-speed. Everything feels much smoother across the board. Still managed to pull off 17.2 mpg on a 22 mile trek into Phila today for work. Plenty of power in 4H.
I had my local dealership install my Mopar lift and 35s on my '18 JLU Sport S in order to make sure my warranty was not voided, and because they installed the lift purchased through them, the lift and all components are also now covered under the factory warranty. Adding a lift and tires should not void anything, but unless the dealer installs it they won't cover anything. Seeing we're in the gearing, axle, driveline thread, I also just got a quote from the dealership yesterday to install brand-new Rubi axle assemblies on my Sport S and wasn't too disgusted by the quote. All parts, labor and taxes rolled in will be $3950 front, $3350 rear. I'm totally going to do it, but need to wait until bonus time this December...Except, I can throw my factory wheels and tires back on the Jeep in 15 minutes if I need to go in for service. Can't do that with a ring and pinion swap.
Hey Matto!my 4.88 gears are in transit right now! Will be running Toyo 38s
