Did Re-Gearing My Jeep Gladiator Affect the GAS MILEAGE?

[@TrailRecon]

It wasn't mentioned in the video, but yes I did recalibrate my speedometer to compensate for both the tire size and gear ratio. As for why I chose 5:13's, I think 4.88 is a good ratio to go with for a 38" tire, but because I carry extra gear and plan on doing some off-road towing I wanted to go slightly deeper, and that's why I chose 5:13'. Sorry for not explaining that in the video.

[@robertkeck2905]

TrailRecon I am concerned if the slight increased rpm (4:88) will move it up the horsepower curve enough to still pull 8th gear at interstate speed (75 mph). I realize I am on the verge of asking to much. You did confirm you see 8th a lot more with gear swap.

[@michaelnewman89]

What’s your rpm at 70mph in 8th gear ?

[@PhilGBeebe]

Thanks for answering my question before I could ask it.

[@brianmillican4985]

What did you use to recalibrate your speedo?

[@JeepGladiatorestAprilJTR]

I’m currently running 37 Pats, would you recommend 5:13s if I plan on building my rig similarly to yours as far as weight is concerned? Thanks Master Chief!🤙🏽

[@marnielarocque9412]

Wow, gentlemen, I am so impressed that i subscribed, I`m an old disabled mechanics and over the years explained or at least tried with some guys to explain what happens with bigger tires and gearing, and then of course, braking and shocks, so many other sites just add tires and never explain the changes in bottom end performance versus top end and real-life changes. Well done!

[@expert244]

The MPG gain wasn’t super impressive, however the increase in MPG PLUS the extra low end power is a win IMO.

[@rareearthfab5511]

Great Job Brad! I do a lot of gears for people and explaining what you have found in this video people don’t believe me. Not only do you pick up a little mileage but it’s so much more fun to drive a properly geared 4x4 on or off road.

[@TrailRecon]

Thank you! Great to hear you are seeing similar result!

[@MattsCollection]

The added weight of the breakfast burritos has made this test invalid! :D

[@TrailRecon]

LOL!

[@tjshine8022]

Wow, I called it at 17.2mpg! On my 96 Chevy, 350 AT, 35" BFG's and 6" lift I went 3.73 to 4.56 gears and went from 17mpg to 18mpg on the highway. But City went from 13 to 15 because the lower gears made it easier on the engine to get to speed. Gears will help your engine and mileage, it may just take a few years of driving to make up the $2,000 price of them. Great study!

[@xTinBenderX]

Had a 26' Penske loaded and towing my CJ7 on a trailer. The truck's rear tire developed a bad vibration over 50 so I had to drive from LA to OKC doing 50. I got 8 mpg before the vibration and 16 mpg after. Lesson learned about pushing air.

[@michaelhalstead64]

Hey brad. Having had both 4.88 and 5.13 gears, which would you recommend for a daily driver? Is there that much of a difference? How do they compare on the interstate?

[@built4xploration253]

Was cool seeing my old stomping grounds. The tower ( really the caves) holds a special memory for my wife and I. Oh, and holy crap, I cant believe 87 is $4.03!!!! I am reminded of one of the reasons I fled CA.

[@jeepwrecognizejeep1391]

There's a fine line between making a KZbin channel successful and selling out. Where does one draw that line and find that balance? Started from scratch and as a channel grows the more sponsors it attracts. The more sponsors one gets, the more it starts to look like an infomercial, biased and unorganic. Then along comes the haters and trolls. How does one know where to draw the line before their channel gets too big to the point where the content becomes unrelatable to the average Jeeper?

Great video with some good conversation about all the things that can go into ruining or increasing your gas mileage. I think people don't realize how big a difference regearing can make when you jump more than a couple inches in tire size from factory. One of the first things I do to my vehicles now that get more than a small bump in tire height.

[@billp5424]

There used to be a cooking on your engine cook book called Manifold Destiny.

[@roncameron9541]

What a shock to me that you improved your gas mileage! Back in 1969 I had a Z28 Camaro and put 538's in it. Gas mileage went way south! Made the mistake of driving it from Okla to Indianapolis once. Gas was like 32 cents but I was only making 2 bucks an hour. It got to 60 really quickly though! :)) I know the situations are different and tech is different, etc etc, but I was still surprised at your gas mileage improvement.

[@bertvanderzon1048]

Great to see some home turf every now and then! I never knew about the truck museum, but now I’ll have to check that out.

[@jasonveldhuis9471]

In 01 I bought a new gutless 1500 ram 4x4 with a 360 magnum engine. 3.55 gears got 11 mpg max. Tranny blew at 20k, factory reman.Put 33” tires on and got 9 mpg and more gutless. Blew the tranny at 40k. Put 4.10 gears in with a hand built tranny and got 12 mpg, more if it was unloaded and I milked it. Even when it was all stock, it struggled to stay in 4th gear. The 4.10 gears were way better and the transmission lasted another 200k when I sold it for scrap because I live in Michigan and the salt ate it up. I did sell the transmission to a friend of mine who put it in his plow truck and ran it for another few years. I still should’ve went with 4.56 gears though. Those 360 magnums were worthless!!!

[@gogerwi]

Good stuff Brad. It's going to be very interesting to see how a comparably equipped diesel version will do if Jeep ever makes it happen.

[@TrailRecon]

I'm hearing the Wrangler diesel is going to blow the mpg I'm getting out of the water!

[@BackroadExploration]

Love your Gladiator build! Impressed with the MPGs you are getting. I’m getting around 17 on the Highway in my JK. But average around 15 on all around driving including Overlanding trips.

[@JustNobodyButME]

The question will be,"will the mpg on the diesel make up for the increase in cost per gallon?" Of course the diesel engine will outlast a gasoline engine by a long shot and have better overall performance and for those reasons I would go diesel every time.

[@45auto]

My question is how will it take to recoup the additional cost of the diesel engine? Obviously, the cost per gallon is the big factor but how many gallons? There has to be a math whiz out there who can figure that out for us Liberal Arts majors.😀

[@gogerwi]

I've owned 7 Jeeps, all just minimally powered. The diesel is a $4000 option on the Wrangler and diesel cost .40 more than gas. For my personal satisfaction and driving pleasure I will pay the extra cost regardless. Life is short and you can't take it with you.

[@mikehoffman3690]

Modest gain in mpg. Cannot use that as justification to regear but other benefits still make it a worthwhile mod. 👍

[@ronkreed]

[@mssammielowe]

Outstanding content Brad! I think the more you skinny down the items sticking out the sides and top will help.. I seldom get my JT in 8th gear, and I’m on stock 4.10 and stock 33’s I get about 18 mpg around town and close to 21 freeway.. I’m from California and still travel there quite a bit.. I freak out over the price of gas, and many other “California” issues.. $2.66 in Colorado for 87.. We have been as low as $1.89 for 85.. Again, probably one of your most informative vids..

2008 JKUR.. Dealer had put 35's on it already w/2.5"lift. Stock gears were the 4.10's. Pulling a trailer at 70 mph on the hiway, only time it would get out of 2nd gear was downhill. I went to 5.38's (also cryo-dipped them) and I at least stay in 3rd now. W/O trailer, even the OD stays in better. Ya, is the 3.8. But my mpg did come up too.. Varies on what I do, but 1~2 range is common. And yes, I is much more spunky both on street, and crawls crazy great.. Thou, off road, I have use the programmer to set to crawl mode. Too jumpy if don't.. Hiway mpg.. Around 15±. Have been into the 16's under ideal conditions a couple of times. 12.5~13 common around town.

[@prescottlederer3761]

Thanks for another great video Brad! You were going to discuss why you choose the 5.13 over the 4.88 or 5.38 gear ratio? Short answer?

[@robertkeck2905]

Prescott Lederer also want to know as 4:88 puts it closer the factory ratio.

[@TrailRecon]

I think 4.88 is a good ratio to go with for 38's, but because I carry a lot of gear and I will be doing some off-road towing I wanted to with a slightly deeper gear, so that's why I chose 5:13's. Sorry for not explaining that in the video.

[@4bnewb969]

Hi brad Thanks for posting this; an interesting topic and nice adjunct to most off-road videos. Whilst your discussion centered around Wrangler and Gladiator, re-gearing and its results would equally applicable to other 4wd’s. I am chuckling at all the comments being posted about fuel prices you are paying. Here in Australia, A$1.50 per liter is an average. By my rough calcs that is around US$4.09 a US gallon, so feeling your ‘pain’. .....Cheers from Downunder

[@TrailRecon]

Thank you! My Wrangler saw a slight drop in fuel economy when I re-geared it, but an improvement in drivability, but it only has a 5 speed transmission. Different results for different model vehicles.

[@balmasi1]

What was the rough cost on the parts and installation? Curious from a payback point of view on the fuel savings.

[@daveputman4402]

The next time you are in a gas station, look at the nozzle on the hose, you will see a 1/4 inch tube in there, because of CA emmissions, that tube is designed to suck the gas back out to keep it from going into the atmosphere or on the ground. Every time you click the handle after the auto shut off you are putting gas back into the ground tanks of the station

I was told that it does not void the manufactures warranty when doing a lift & regear. There was some sort of landmark case that made it possible to retain the manufactures warranty & they can't drop you for it. I could have been lied by my Jeep shop you never know but this was what I was told. From an internet search: Regearing does not void your warranty, BUT don't expect a Jeep dealer to fix any issues with gears that failed. The replacement parts would be your responsibility to get from aftermarket manufacturer.

I'm curious if you and Ryan gave any consideration to tooth engagement on 5.13 v. 4.88; I've been told the pinion gets pretty small on 5.13 with like only one full tooth of engagement on Dana 44. It is something I've been struggling with as I do not have the 4:1 transfer case, 2.72:1 I think is ratio. 5.13 might make crawling a bit better. So before I put lockers and gears in my open diffs of my JT I would be interested to hear what you and Ryan's thoughts are

[@drtstar1]

harley rice you make good point! If you are going to thrash your axles with big horsepower don’t drop below 4.56 . All the new vehicles put securities in place to keep you from breaking the tiny 1st gear in the transmission. So that helps a bunch protect the ring and pinions. Check out the ratio chart on G2’s website and that will give you an idea of what gears will fit your application and tire size best.

[@drtstar1]

harley rice modern crawl ratios are respectable these days starting in the 60/1 range factory. You can’t go wrong with lower ratios. When you pick your gears be thinking were your build will go in the future. 37’s today? 40’s 3 years from now? I tend to caution to the lower ratio if I’m at a crossroad about it. Hope that helps

[@steamman9193]

I’m still not sold on the need to re gear with the 8 speed. 2,000rpm at 75mph it doesn’t matter what gear your in. I’ve found speed is so critical with these trucks JT at 40mph I get 23mpg on 33s with 3:73 at 80mph 19mpg. Temperature, humidity, altitude all have an impact- they were wearing jackets in the 2nd test cooler dense air yields better combustion.

Hey Ted, any info on your build? I'm thinking about 5.13 vs 4.88... 2020 jtr

[@wibornz]

@@mathewmue5547 I just came home from a 5834 mile wheeling trip. Pulled a small camper. Did 8 days in Mab, then the Rubicon trail, then trails in Wyoming and back to Michigan. Avg 14.5 mog pulling the camper plus off road driving. I get about 18 to 19 on the hyw for normal driving and 15 around town. I see 8th gear all the time even pulling the camper. 8th gear in town above 45 mph. 5.13 gears and never look back. The 5.13 gears are perfect with the 8 speed auto.

@@mathewmue5547 I am lifted with 37s on bead lock wheels, winch. Big bumpers, the heavy stuff.

[@mathewmue5547]

Maybe a silly question, but doesn't that worry you that it blows your factory warranty out of the water?

[@travismcvey]

You'll really notice the mpg improvement @ lower speeds from the regear. That rack kills your highway mpg. I had a huge roof rack on one of my XJs, and it literally got better mpg in town that it did on the highway.

[@FrancoisTX1974]

Nice video, the most impressive was price of the gas.....2$ per gallon in Texas....

[@GoldenK9Campers]

Cool video. Better acceleration and better gas mileage. Win/Win.. You had to reprogram everything for the gears and the tires? Also, there was a difference between the computer and the real gas used on the 1st test, what about the 2nd test?

[@crjmoto]

Cool comparo. I swear I can see the needle dropping on my FJ (16-19 mpg, live in not-flat CO)

[@nodoze]

$4/gal for 87???? Yeah, I'd be worried about MPG if I lived there too.

[@monsterpoo]

that's because it is socialist run commie-california... here in liberty capitalist run FL its 2.20/gal .... socialist arent good with money

[@stevenjaclynsleight983]

Excellent content as always! Now that you’ve “slimmed down” your gladiator profile with the new rack and hard shelled rtt, have you seen an even bigger increase in fuel economy?

[@Sthilboy56]

Your so lucky with gas prices , around $8 per gallon equivalent over the pond in the UK

[@mjongsma64]

Good info I can use as ammunition when I need to upgrade gears. I have JKUR with 3.73 running 35's. I don't know anything different as this my first Wrangler and it's the way it came. Now to decide what gears? Do you think the 4.56 0r 4.88 will have a negative impact on freeway mileage?

[@drtstar1]

Mark Jongsma 4.56 is a pretty popular swap with 35’s. If you are still looking for mileage then stay on the 4.27 side of gearing. If you want extreme crawler gears go 4.88

[@nachovalenti]

Very informative video Brad. Thanks for sharing.

[@RandomeXits]

I free wheel on long downhills. Got 20 mpg one time from Donner to Colfax.

[@dame5014]

I didn't realize bigger tires have such a negative effect on mpg. How it it possible that it has a negative impact on breaking? The size of the rotors aren't changing, just the height of the truck. I mean, the r..... Hold up, I just realized it lmao. NVM. It make sense to me now

[@mariodelai624]

Lucky you guys in the USA, fuel prices are ridiculous in there

[@OCMortgageExperts]

Looking forward to seeing how the Diesel version of the Gladiator does in a similar test

[@wildthingsgarage]

Excellent little test! It's nice to see real world tests for stuff like gear upgrades. I'm curious, do you have stock, or aftermarket lockers? How much would lockers affect gas mileage? Thanks for the great content!

[@gregsheridan]

Brad, you are talking about 16-17.2 MPG in the video but your math and captions actually show 15.2-17.1 MPG which is 12.5% improvement! Very impressive with the weight and lack of aerodynamics.
