Yes, 4:56 gears will be a perfect match even with your auto trans. Given your model year Jeep you'll need to have the ECU reprogrammed for the new gear ratio, this way your have proper shift points. If a 4x4 shop is doing the re-gear then I'm sure they understand this process. thanks for watching
4:10 is a lot better than 3:73 or the 3:21 gears but your 8 speeds trans is what’s helping your JT with 35’s feel like it’s still on stock tires. JK’s had 4 or 5 speed autos and 6 speed manuals so larger tires really were a lot more noticeable in performance lost.

4.88 is the basic starting gear ratio for 37in tires. Based off where you live ( high altitude ) and other Jeep specs and equipment 5.13 could be an option. Thanks for watching and glad the video helped.

The 4:56 gears with these 35’s is basically drives and feels like stock, geared for every day use since we drive it to all trail heads. At some point it will be geared for trail use since we’ll trailer it more or all the time.
I would recommend 4.56 gears but make sure the shop that performs the regear can also reprogram for proper shift points. A local friend of mine has a 2012 and 2013 JKU on 35's and he loves the 4.56 gears in both Jeeps ( he jeeps run around 2600-2800rpm at 70). If your Jeep is lightly built and is a 2 door and doesn't see any off-road use you could run 4.10 gears. But if you are looking for total performance on and off-road and have plans to build up the Jeep I'd go with 4.56 gears.
Appreciate your video as always. Great information! I just ordered a 2024 Rubicon X. I can't decide if I should opt for the 4.56 or 4.88 gears. I don't plan on pulling a trailer but I will have a roof top tent and overlanding gear in the back. It is my daily driver but I work from home so not a big deal. I figure about a 20% chance of me ever moving up to 37s. I am concerned about my MPG as I live in California where gas is almost $6 a gallon. Do you think it will affect my mpg a great deal? Most of my off roading is in the mountains.
Thanks for watching! Adding weight and accessories will cost you some MPG. Proper gear ratio for the tire size will not cheat you out of MPG. With additional weight and overland gear you’ll want proper gears for tire size. 4:56 would be fine choice.

So what gear ratio is the best for automatic Please let me know Thanks ○|||||||○ ° °
What size tire are you running? Gear ratio selection should be based off tire size, usage (trail rig or daily driver) elevation, and overall Jeep accessories like heavy bumpers, gear, etc.
@@Georgia4Low Hello Dirt Hammer Thanks for the reply I'm running 35x12.50r20 tires M/S it's what came with the jeep when I bought it from the Dealer ship
@@davidmilovanovich9415 likely the trans is shifting funny due to the larger tires. It’s harder for the trans to get into overdrive with the larger tires. If you regear it for the proper tire size the ECU will need to be reflashed for proper gear ratio and trans shift points.

@@davidmilovanovich9415 not shifting into reveres is not related to gears or tires so likely there is an issue with the trans internally. Returning to stock will not fix a shifting issues into reveres.
4:88 gears would offer better 4low crawl for technical terrain, could even offer better ability if you wanted to tow a small trailer, or you lived at higher elevation. Thanks for watching
If you have stock 3.55 gears then 4.10 should be good but I recommend checking with a few more folks that have better knowledge regarding the TJ model Jeeps.
I see this is a year old comment. But.... I just drove my 97 TJ Home w/4:56 installed (33" tires). I asked for 4:10/4:11 when I went in but the shop's owner and his assistant convinced me that 4:56's was the way to go with a 5sp manual. The 1st ten miles.... I'm not happy. If I drove off road.... Maybe? But at this moment... I'm not happy. I think it's too much gear for my type of driving and the stock wt. of the jeep. I'll test it a month before I decide to pull it out.
Considering regearing my dana 30 front and dana 44 rear on my 2020 jlu sahara altitude to 4.56. Running 33’s from dealer but will jump to 35’s later. Is this gear ratio good?
Depending on where you live the the 4.56 gear could be a tad much for 33in tires. Like I mentioned in the video altitude, Jeep use, weight, etc all affect what gear ratio you should select. 4.56 gears are perfect for my heavy Jeep here in the Southeast with 35in tires, it’s like driving a stock Jeep again.
Not sure why someone would give this excellent content a thumbs down.

I don't plan on pulling a trailer but I will have a roof top tent and overlanding gear in the back. It is my daily driver but I work from home so not a big deal. I figure about a 20% chance of me ever moving up to 37s. I am concerned about my MPG as I live in California where gas is almost $6 a gallon. Do you think it will affect my mpg a great deal? Most of my off roading is in the mountains.
Thanks for watching! Adding weight and accessories will cost you some MPG. Proper gear ratio for the tire size will not cheat you out of MPG. With additional weight and overland gear you’ll want proper gears for tire size. 4:56 would be fine choice.
Hello
Drit hammer
I just got a 2013 jeep wrangler unlimited SAHARA V6 3.6 automatic jk GECKO PREARL GVWR 5500
So I think gear Ratio is 3:73
Has a lot of zip but transmission shifting funny
😬
I'm 66 years old and on disability I would like to set it up to help people this winter if they get stuck I'm going to install a 9000,lbs winch
I live in Wisconsin
Not to many place's that know about jeep transmission shifting problems with over size tires, ? So what gear ratio is the best for automatic
Please let me know
Thanks ○|||||||○

What size tire are you running? Gear ratio selection should be based off tire size, usage (trail rig or daily driver) elevation, and overall Jeep accessories like heavy bumpers, gear, etc.

Hello Dirt Hammer
Thanks for the reply
I'm running 35x12.50r20 tires
M/S it's what came with the jeep when I bought it from the Dealer ship
@@davidmilovanovich9415 likely the trans is shifting funny due to the larger tires. It’s harder for the trans to get into overdrive with the larger tires. If you regear it for the proper tire size the ECU will need to be reflashed for proper gear ratio and trans shift points.

Hello
I do have a supper chip pac
It doesn't seem to help much
I don't have a computer to update or upload
To night it didn't go in reverse at first it sometimes does this when it is warm the dealer ship don't want to do anything they just said put it back to stock I said I didn't alternator it you sold it to me this way 🤧
@@davidmilovanovich9415 not shifting into reveres is not related to gears or tires so likely there is an issue with the trans internally. Returning to stock will not fix a shifting issues into reveres.
What Soft top setup is that?
It’s a SunTop cargo top with cargo rack.
Is the speedo corrected for your tire size?
Yes the speedo had been corrected prior to video.
So how would 488 gears be better ?
4:88 gears would offer better 4low crawl for technical terrain, could even offer better ability if you wanted to tow a small trailer, or you lived at higher elevation. Thanks for watching
@Georgia4Low thank you.
But for everyday driving like stock would 4.56 gears be better ?
Also if I was to use 37s would 4.56 be good ?
Everyday driving and even off-road the 4:56 gears are great. If you run 37’s go with 4:88 gears
For my TJ 5-Speed, 4.0L, on 33's, would you recommend 4.10's or 4.56's?
If you have stock 3.55 gears then 4.10 should be good but I recommend checking with a few more folks that have better knowledge regarding the TJ model Jeeps.
Again some things depend, added weight to the TJ Jeep, type of trail work, and elevation are just some things to consider
@@Georgia4Low, thank you for your response and advice!
You’re Welcome!
I see this is a year old comment. But.... I just drove my 97 TJ Home w/4:56 installed (33" tires). I asked for 4:10/4:11 when I went in but the shop's owner and his assistant convinced me that 4:56's was the way to go with a 5sp manual.
The 1st ten miles.... I'm not happy. If I drove off road.... Maybe? But at this moment... I'm not happy. I think it's too much gear for my type of driving and the stock wt. of the jeep.
I'll test it a month before I decide to pull it out.
What did your mechanic charge you for the installation?
B and R Automotive in Cartersville, GA charged $300 per axle and $60 for Diff fluid. Thanks for watching
@@Georgia4Low very gd..I live in upstate ny..I just got a quote to install 456 yukon gears in my jk for $575 plus tax and oil
3767712 nice, that’s a great deal. I’ve seen some shops charging $600 per axle.
I'm looking forward to the 456 gears on my 6 speed and 35inch rubber.great vids
You’ll love it!! Thanks for the support.
Considering regearing my dana 30 front and dana 44 rear on my 2020 jlu sahara altitude to 4.56. Running 33’s from dealer but will jump to 35’s later. Is this gear ratio good?
Depending on where you live the the 4.56 gear could be a tad much for 33in tires. Like I mentioned in the video altitude, Jeep use, weight, etc all affect what gear ratio you should select. 4.56 gears are perfect for my heavy Jeep here in the Southeast with 35in tires, it’s like driving a stock Jeep again.
