Oh my bad man I was too busy trying to type and didn’t refresh LOLYou don’t say.......
Lol!
Im not sure yet honestly. I go back and forth and since my wife approved of the Gladiator in the future and keeping the JLU it’s changed my outlook potentially.So, @MORTON what’s the plan you are making for your Jeep? Looking forward to seeing it.
My bad, the 10-speed GM/Ford has 8,9,10 as overdrive gears.The automatic has two overdrive gears not three; 7th (0.84:1) and 8th (0.67:1) as 6th gear is 1:1
In the video they didn't claim it to be totally scientific, and considering the 4-month span between tests, there's plenty of room for discrepancy. They also didn't mention how well the odometer was calibrated before each test. My experience hasn't been 10% increase. It's been a wash or decrease. Again, big performance boost on old 4-speeds, but not much to gain with modern 8+ speed transmissionsRe gearing to the proper ratio for tire size actually does increase fuel mileage. After over a dozen Wranglers, I know what I’m talking about. This dudes experience is the same.
Not trying to talk you into regearing. You obviously can do what you want. New guy was asking for firsthand experience, I gave him mine.In the video they didn't claim it to be totally scientific, and considering the 4-month span between tests, there's plenty of room for discrepancy.

My apologies, It's a Monday, I may be a wee bit too aggressive at the moment...Not trying to talk you into regearing. You obviously can do what you want. New guy was asking for firsthand experience, I gave him mine.
No worries man.My apologies, It's a Monday, I may be a wee bit too aggressive at the moment...
Your profile shows that you have a JK and you mention JK in your post.Does anyone here have experience running stock gearing while running 37+ inch tires??
Can you tell me what jeep you had even if it was a previous JK. Did it damage anything? What kind of terrain did you drive on? Length of time/miles? Anything and everything you could tell me about the experience is greatly appreciated!!
i do have a jk with 3.73 diesel 2.8crd. I'm in Korea so we have the euro model. But I have some friends with JL's and the 8 gear trans and was getting opinions from you guys. What I take is, 37''s are fine with the 8 speed and a tazer to adjust the speedo/gear shift timing. it may not be the optimum scenario but it's not detrimental to change the gears.Your profile shows that you have a JK and you mention JK in your post.
If you have a JK with 3.21 gearing, do not attempt to run 37" or larger tires. The jeep will be a slug. I drove a JK on 37s that wasn't regeared once. Seriously had to press the pedal halfway to the floor to start moving on flat roads...
37s will work on an auto JL Rubicon which has 4.10 gears. I wouldn't reccomend it with the Sahara or Sport which have 3.45 gears.i do have a jk with 3.73 diesel 2.8crd.

True, and I agree. I see no reason to re-gear with 37's but the turbo motor is a whole other story. I had a JLUR on 37's with the V6 and with the 8 speed it was fine but you did have to really wind it out to go anywhere, so I can see some people definitely wanting gears. Not so with the turbo.I'm not an expert, just wanted to add my personal experience. I have a 2020 Willy's edition JLU that has the 2.0L turbo and the 8 speed automatic and 3.45 gears.
The 2 local off-road shops swore I would have no issues going to 37's, which I found hard to believe, as I thought I'd need to go to 4.88 gears.
After 600 miles on the 3.45 gears and 37s, having done mountain and desert trails, and gone up over 6k in elevation on steep mountain roads, they were right. That transmission, paired with the 2.0L turbo is insane. While there is some very slight loss of power, I am having no issues at this point. It's possible I'm not using 8th gear, but this is something I need to pay closer attention to to see. I'll try and test that and post again.
Will I feel the same way 5k miles from now? Who knows, but for now I have no plans to re-gear. And yes I am just as shocked as you probably are reading this.
