About darn time someone did the real world comparison. Thank you for this. Great job.
Thanks for watching. Now that I have 5.13s I have zero regrets. 4.88 would have been ok too. It’s not really a huge deal but it’s great to see the difference and make your choice. Thanks for watching!! #JTRSPARTACUS
I can hear that Centerforce Clutch roooar love it!
Great job. Love the side by side comparison.
Glad you liked it! Thanks for watching. #JTRSPARTACUS
Thank you! I’m going w/ the 4.88’s
Nice! Good luck. You really can’t go wrong with either. #JTRSPARTACUS
Great comparison
Glad these are useful. Thanks for watching!! #JTRSPARTACUS
This was great 👍
Awesome video!!!
Thanks for watching! Glad you enjoyed it. #JTRSPARTACUS
Great video ! Thanks fellas !! Honestly being a former machinist it's really about what I'd expect , 488 & 513 are really similar and shouldn't have a huge huge difference between the two. Now if we're talking 438 to 538 I'd expect to see a bigger more noticeable difference.... I am curious to see the MPG difference between the two? Actual calculations not digital dash readings lol
Thanks for watching. I’d guess mileage differences would be negligible. Lots of factors with the driving style, traffic, terrain, and vehicle weight being big ones. I did a trip to Yellowstone and back from PA and calculated 15.6 mpg - dash showed 16. I get about 13.6 driving around home in hilly PA in short trips and usually lugging stuff. #JTRSPARTACUS
great topic, thank you. will be upping to 37's and needed this info--basically, not much difference but as long as pricing is similar i think i will opt for 5.13
I believe the prices were basically the same. You’ll love 5.13s with 37s!!! #JTRSPARTACUS
Good video. I would like to see the first 1-4 gears side by side. I have people telling me if I go with 5:13 that I won’t have a first gear.
I have 1st gear and use it daily. It’s short but unless it’s completely flat or downhill, I use 1st to take off. The difference between 4.88 and 5.13 is about 5%. I’d rather have the extra 5% lower gears in the mountains or when towing. Thanks for watching. #JTRSPARTACUS
Thanks for this vid. Got a JL Sport with 6MT. Doing research on gearing bc I would like to upsize tires in near future. Nothing crazy. Def 33 MAYBE 35. Got the stock All Terrain Wranglers. Haven't had a chance to take her off road yet. Will see how she does. Who knows, I might keep it bone 🦴 stock after all is considered!!!
Def gonna put an exhaust tho 😇
Glad I could help! Good luck. #JTRSPARTACUS
Where are you? Those trees behind you were absolutely GORGEOUS!!
Southern Chester County, Pennsylvania. Thanks for watching! #JTRSPARTACUS
Im glad i found this because i have a 6mt mojave wondering if different gears function different compared to at
Nice! #savethestick
You really can’t go wrong with either. Good luck!
#JTRSPARTACUS
Btw (I'll try to correct this later if I'm wrong), but my Stock JT Rubicon manual is maybe at 3200-3300 RPM in 4th gear at 60mph. I haven't bothered looking at oil pressure though.
EDIT: Numbers were wrong, see the updated numbers below, if you're curious.
Seems a bit high for stock gears and tires in 4th gear. Oil pressure goes up when over 3,000 rpms. Not sure it’s a big deal unless you run like that for a long time. Like everything. YMMV. Thanks for watching!
#JTRSPARTACUS
@@JTRSpartacus You're correct, they were too high lol. It was actual about 2600rpm at 60mph and about 32 for the oil pressure. The number I was thinking of was 4th gear at 75mph, that was closer to 3200rpm.
I did notice that there was about 30 degrees difference in air temperature. I wonder how much that affected the test. Other factors would be actual tire size, pressure, and difference in height above sea level.
All very interesting. Thank you for posting!
Not scientific but still useful. Thanks for watching!! #JTRSPARTACUS
One truck is Fahrenheit, and one is Celsius. 34 degrees F to -1 C is a difference of 3 degrees Fahrenheit. Virtually no difference.
Good catch! Again - not scientific but a reasonable comparison. Thanks for watching! #JTRSPARTACUS
In a manual, the engine speed vs all those other variables doesn't matter since it is a mechanical connection
Damn I wished this was an 8 speed auto comparison. I am at around 2400 Rpm going 75 on seventh gear on 4.10s on 38s. I might get my 8th gear back with 4.88s, 5.13s might be too much.
Thanks for watching. Probably not too much at 5.13 for 38s. Really depends on where you live/drive and what you use your JT for. #JTRSPARTACUS
I think the 5.13 would be totally fine the overdrive is insane on these
Woowww finally the video that I was looking for, great video, very informative and excellent explanation !!!!! do you think that it can be the same results with my jk 2014 6speed if I switch to 5.13 ? I don’t know the difference between JL 6 speed and JK 6 speed, thanks a lot for amazing video
Different transmissions, with different ratios so it will be a bit different. The basic ideas is similar. The JL Wrangler and JT Gladiator use an Aisin D478 trans with these ratios
1st - 5.13
2nd - 2.63
3rd - 1.53
4th - 1.00
5th - 0.81
6th - 0.72
Reverse - 4.49
The JK Wrangler uses the Daimler NSG370 manual transmission.
1st 4.46
2nd 2.61
3rd 1.72
4th 1.25
5th 1.00
6th 0.84
Reverse 4.06
Good luck ! #JTRSPARTACUS
@@JTRSpartacus thank you so much really appreciate it!!!!!!!
Like to see this with auto and also maybe a 0-60 test. What’s the difference at lower gears when coming up to speed.
Good question
i love the way you guys do the real world comparison but, i'd like to ask regarding the road you guys are taking. . was it uphill or on level surface? thank you !! more power!
Almost no true level spots where I live in Pennsylvania can’t say for my colleague in Canada. In PA it’s small hills that go up and down and average out. Not scientific but a decent comparison if I do say so, myself. Thanks for watching. #JTRSPARTACUS
hello, congratulations on your good work, thanks to you the consumer is carefully informed. now i have an ambiguity for the ratio of my gladiator rubicon, i live in quebec in canada, my job is snow removal with tractors, for moons, everyone knows that a jeep is superior to a truck. I want to install a front plow to push snow. in the summer I have a boat that weighs 3000lbs, I am often on the road for travel, my top speed here in Canada is a maximum of 120 kilometers per hour. what would be the best ratio for my utility, the ideal for me is the maximum of force and power while respecting the speed of the engine at approximately 1700 revolutions in 8iem clutch. thank you !
It really depends on what size tires you are running. If you are running stock size tires the stock 4.10 gears are just barely adequate with the manual transmission. You may want to look at 4.56 ratio gears for stock tires and plowing. If you go to taller say 35” tires you may want to go up to 4.88 gears but even 4.56 ratio gears will be better than stock. Be sure to buy quality gears and use an experienced mechanic. Thanks for watching and good luck! #JTRSPARTACUS
Cool
Thanks 🙏. Appreciate the support!
Nice vid! Any concern with the clutch recal? With regearing?
I did the Centerforce clutch because the factory clutch was woefully inadequate and I didn’t believe (and still don’t) that Jeep would make it right. This replaces all the faulty components with hood parts so zero worries. Thanks for watching! #JTRSPARTACUS
Nice comparison, didn't see much of difference until North of 75 MPH (120 KMH). Btw, got any merch?
Thanks for watching. I’ll have some Centerforce stickers a d a Centerforce t-shirt to give away for that video. Hit the notification bell 🔔 for updates! #JTRSPARTACUS

I would have liked to see the difference with a trailer. Around town without a load on the truck is minimal.
I’m not against this but there would be some logistics involved. Ideally we would need two trucks in the same place, same loop, same trailer. (Blake lives in Canada 🇨🇦 and I live in Pennsylvania 🇺🇸) we would need 1 with 5.13s and 1 with 4.88s. I’m open to a collaboration and have a trailer we can load up if anyone in the Southeast PA, DE, MD, South NJ area has a manual Gladiator on 37s and 4.88 gears. Thanks for watching and commenting. #JTRSPARTACUS
Something to consider with the manual. First gear in 4H is awesome maybe better than AT but 2nd gear feels tall in stock form. If you like to air-down tires, 37s might be better off with the 5.13?
2nd gear is a bit tall on the manual. In 4wd low, I can put in 2nd and crawl up a 20degree hill without giving it any gas.
So for 38in tires, do you recommend 5.13?
Probably be ok. For auto trans 5.13 will likely be great for 38s. Depending on the tire weight and your use (especially if towing) you might want to look at 5.38 gears for manual transmission. Thanks for watching and good luck! #JTRSPARTACUS
Will re-gearing to 4.88 gears through a code or check engine light on my dash ? Do you have to re-flash the ecu?
You’ll need to get a Tazer or other programmer or have a dealer reflash to correct the Speedo. There is also a relearn procedure - basically drive 20 seconds in 6th while accelerating - I have another video on my channel of this . I have a Tazer mini programmer. Good luck! #JTRSPARTACUS
Relearn for manual trans is here ua-cam.com/video/Af0Qhi7wSBs/v-deo.htmlsi=pwZwAAan-Uvbz5Ce if auto trans - there may be something different.
Did you also GPS the speed ?
We both previously calibrated our speedos with Tazers and checked against GPS.
How is your takeoff with the 5.13s, I have a 2023 Willys Sport, and the take off is horrible, stalls easier than a mid 90s ford escort, reverse up hill or out of a hole is nearly impossible without side stepping the clutch, and i really have to feather the fuel in 1st to get going
Also Im on the factory 255 tires and 3.73 gears
Take off is much better with 5.13 gears and 37s. It’s not fast but it is responsive. If it’s flat I can take off in 2nd gear ⚙️. Thanks for watching. #JTRSPARTACUS
What’s your average MPG with 5:13’s ?
Getting about 15.6 mpg calculated by hand in back road/hilly local driving. About 1 mpg less thank stock 4.10 and 33inch tires. Display is showing 16mpg so it’s not that far off. Thanks for watching!
Does it feel different?
THANKS for watching and for your comment. It does feel different. 5.13 gears feel so much more powerful than the stock 4.10s with 37” tires. I got 5th and 6th gear back. It was a dog on the highway and trail with stock 4.10 gears. Checkout the first tow video for an example ua-cam.com/video/z74sj07lc4Y/v-deo.html #JTRSPARTACUS
If the question is do 5.13s vs 4.88 feel different. I’m not sure. Probably at least a little bit. Blake is in Canada 🇨🇦 and I’m in Pennsylvania 🇺🇸 so this was a virtual collaboration. I’m open to doing a back to back in person comparison if anyone is in the PA, DE, MD, Southern Jersey region with a manual JT, 37s and 4.88 gears.
Ok. Cool, good to know. Our family is new to the Jeep family and we got a 2021 manual rubicon gladiator. Weve done nothing yet because we just dont know anything and I was curious. Just myself, I'm a short lady so I've never really driven a manual pickup before this jeep. I'm pretty good with any manual sedan, but this truck is definitely taking me some time to get accustomed. We live in Hawaii so not much opportunity to get above 50mph so I find myself most comfortable really around 3rd gear. I like to keep rpms around 2000at most for manual sedans, but it's not as natural or easy in this truck. My husband does the driving when we go offroad, lol.
@@christinabruce5660 thanks for watching and welcome to the Gladiator obsession OlllllllO!!!
Not much
Yeah this is exactly why people should opt for the 8 speed auto. My sport on 33s can cruise at 80mph on the interstate at 2100rpm and get 20mpg. Bigger tires? 7th gear and 37s run an almost identical final ratio to stock and you still have another gear over the manual option. Plus the auto is so fast on a gearshift your always in the right gear for the situation
Thanks for watching. To each their own. Everyone should buy/build what works best for their lifestyle and needs. The auto is nice and smooth but I enjoy rowing my own gears and used the $2k I saved to buy mods. #JTRSPARTACUS #savethestick
Problem with the auto is it will not let you slip down to a lower gear manually at times when you need it due to preventing from reveling up engine too much and only goes up to a certain RPM on its own. Manual is nice to just release the clutch and Krawl away.
RPM-revolution per min not revolution per minutes. 🤦♂️ good comparison otherwise 😂
Doh ! Thanks for the correction. I know that but It’s pretty easy to mess up. Thanks for watching !!! #JTRSPARTACUS
