Bigger Tires (33’s to 40’s) on Dana44 axles - Jeep Wrangler Eco Diesel Build Update

I mounted 40 inch tires on my Eco Diesel Jeep Rubicon Unlimited. I tell you why, how, and what things to consider when going this route in the modification journey.

Did you catch the true tire size measurement of the Cooper Stt Pros in the video? Check out Northridge4x4 KZbin channel for more tutorials: youtube.com/@northridgenation

[@brohammer]

looks like about 39.5?

[@mikepierson3097]

Yep… no tire is 100% true size but STT Pros and Nittos are the closest.

[@southwestoffroad]

This looks really good. I'm sold on getting 44"s vs tons. I've seen plenty of people with the right 44 setup and 40's that are running just fine.

[@artm6723]

I love this! But we all know modding is such a rabbit hole! That being said I'm so glad you're taking us along for the ride! I'm sure this is going to be awesome!

[@TrailTime.]

I’ve ran the same wheel with 39” Km3’s and 5.13’s in 44’s for years now. Nate was right, just remember you have big tires and you’ll be good.

[@Adrian-rn1ym]

Is yours a gasser or diesel ?

[@TheOneWhiteST]

Love to see this! I went with a 3.5" lift and moving to 37s" later this year. Still getting decent MPGs believe it or not Lol!

[@kayloradventure]

37's are a good sweet spot. My JL 2.0L turbo is getting over 18mpg in mixed daily driving.

[@SpawnOfOden]

Always love your information in these videos, Ed!! You keep it real, like explaining the cons to upgrading to the higher tire size, and you do the numbers work which is huge (MPG, RPM's etc). Your content is top freaking tier brother!

[@KrokemOutdoors]

Thanks Thor!

[@Handwerkers]

Awesome video as always @KrokemOutdoors ! That was my sarge green JL on the lift at the beginning of the video! Very happy with the build and Northridge's work! 😀

[@betzaidavazquez5579]

🎉🎉Congratulations Edward !! Dusty is looking great, Cant wait to see you take him out and about. Thanks for sharing and all for all the info. 😊👊

[@KrokemOutdoors]

Thanks Betzaida, as always!

[@jthor8373]

40s really are the new 33s especially on the JL and JT. Very little work needed to fit those and that's what I love about it.

[@lol123321123321]

40s are the new 35s. 25 years ago lifting and modifying your rig to fit 35s on a 15" rim was HUGE. Now a days you can buy a vehicle off the dealership floor with factory 37s.

[@robormiston2841]

I grew up in Silverdale where Northridge is. I used to ride up the ditch in front of his shop befor it was there 30 years ago on my dirt bike.

[@MuddyBeards4X4]

Looks awesome! I see we both have the stt pros now. Looking forward to hitting the trail once I get the S10 done🤟🏻

[@KrokemOutdoors]

Same, it’s been a while!

[@jacobboughton506]

You went really deep on the gears, for the diesel. In the JL/JT Eco Diesel Jeep pages the general consensus is 38-40’s is 4:56 and 4:88 for more of a trail only side. Speaking of 40’s only on the Eco’s 4:10 get 20mpg 4.56 get ~23mpg 4:88 18-20 5:17 16-17 Sweet spot for most have been 4:56. I’m on 38’s still rolling 3:73’s and on average get 18.5-20mpg. I would love to regear but not for awhile. Still have loads of torque and I do tow. I’m pushing 68k miles on our 21. Banks power was a nice power bump but for about same price GED has emission complaint tune that been getting great reviews as well. Now EOC across the north border has full on weight loss and seem to be the best on everything from a spectator’s perspective. Looks great.

[@mikehunt-ew3pm]

I ran rock crawler 10 years ago... great suspension great flex, might even need limit straps or the coils will come loose

[@phillipcraddock8248]

The humans that do this kind of work are AMAZEING,

[@fish0n2]

Looks like a very capable Jeep now, looking forward to some cool rock crawling videos keep up the good work

[@TACTICALNOMAD]

@Edward Shin, Great dive into the mods you're doing! 👍🏼👊🏼Personally, I would truss any 5-lug axle running 40s, especially with such aggressive tires like Cooper's. Axle wrap and excessive torsion is a very real thing with all of that dynamic weight turning on such a small axle shaft. Maybe ask Nate @Dirt Lifestyle to help you do that?! And with 1-ton axles and 40" tires you won't lose ground clearance. I had Mickey Thompson 40" tires on my '87 Bronco w/1-ton F-350 axles back in the day and I never had a ground clearance issue, and only a one time minor issue with being high-centered down a deeply rutted mud trail. I ran 37" STT Pros on my '99 F-350. They are a GREAT tire. They are the only tire I'd run over BFGs and Wildpeaks, but nowadays they are cost prohibitive compared to BFG & Wildpeaks.

[@davidharris1767]

Nice build. Mod in stages, Take it easy on the skinny pedal. Great channel.

[@GadsdenJL]

Good stuff! At least wear the balljoints out first, but you should swap them aluminum knuckles. I run 37 sst pros on my 2djl. They do great in deep snow, but its hell driving on snow-covered roads that others have driven. It wants to drag you into deep snow or ruts pretty bad. Its even worse in my shorter wheelbase. Not the tires fault, just the way it goes with big wide tires in the snow. I'll be replacing the sst with another set of sst, outstanding tire. Cool video, thanks for sharing!

[@scotthrncirik9091]

Looking great! Can’t wait to get back out your way and hit some more difficult trails! Keep it up!

[@KrokemOutdoors]

[@iamnoone5248]

On my old JK, I had 40s and stock axles. Truss and guss. Stock axle shafts and 5.13 gears. Been through Rubicon and Fordyce. It's all about the driver. Don't hop that's all. That's how sht breaks. Just crawl slowly and you'll b fine

[@Reaper-ef9ht]

Hell yeah brother the Jeep looks sick I’ve been running 40” STT’s on my F350 last couple years they are the best tires I’ve ever ran think you will love them!

[@hoss6048]

Dang you are getting Rubicon ready for sure.

[@redhillsoverland]

Such a wicked setup! Looking forward to seeing the shakedown run!

[@FieldWorxoverlandadventures]

You made the right choice with Rockrawler suspension, I feel their suspension is the best on the market for jeeps, I’ve owned 14 jeeps and always used rock crawler, just received my new 2023 392 and my parts came in last week from Rockrawler 4 1/2 inch lift very similar to yours, I have a set of 37 inch tires and a set of BFG 39 1350s I’m going to test both out and see what I like best, I like the way you have set up your jeep you’ve used good quality components, and you should have good luck with those tires, i’m considering those same wheels I’m just concerned about the legality of running bead locks here in Northern California on the road, I would think if an officer knows it’s a beedlock and pulls you over and you’re out of town what would happen? Could they stop you from driving? did you install flip kit for your drag link? thanks for the video!!! you do a good job with these!!👍

[@vincentmamotos9937]

Small pinion police. I've talked to many shop owners and engineers. The ring and pinion sizes on this m210/m220 advantek are so advanced and so much beefier than when the whole "breaking pinions" started happening around the JK's lifespan. Theyve regeard thousands of these new advantek axles and put 40s.Theyve yet to see ring and pinion break. the ring and pinion IS NOT tiny on these 3rd gen dana 44s.

[@jinoh7418]

I'm considering 40s on my ecodiesel, currently on 37s with metalcloak 3.5".

[@KrokemOutdoors]

get those chromoly axles and re-gear if you can

[@jinoh7418]

@KrokemOutdoors you don't think trussing the axles and Cs would help? I figure 4.56 would be the closest gear ratio for 40s.

Boy's listenup , back in the early 80s i had 44in. Monster Mudders from Dick Cepek on my 72 ford highboy with a closed nuckle 44 HD with Stock axles and a true trac in front ! I was in the Firewood buisness and only 1 time i broke a long side front axle with a Cord of Oak loaded on , and i made the mistake of backing up a hill due to easy loading of wood ! I had to backup about ten feet to turn around and POP !! Other than that The Rubicon trail or 3ft of snow Never bothered the 44 , But i wasn't hamming the gas peddle all the time and that makes a huge difference
