Cool Video, I also have no issues with running 35's with stock gears (non Rubicon). Slow and steady (but not that slow). Thanks for posting the link for the build sheets. Cheers!

[@HaRtAnDsOuL99]

My 03 4.0 5 spd on 35s is 4.88 and it’s amazing. So happy with it. Dana 44s too

[@SmokinMonkeyOG]

Ya that’s what I hope to get when I swap mine out

[@charlybrown954]

Great information, thanks a lot.

[@realitycheck8944]

Put a 2" lift in my womans 04 TJ Wrangler with the 4.0 , 5 sp.manual. Didn't want to over do it so I went with the 31" Goodrich whiteletters. This was a Florida Jeep and now we all reside in Texas. ( God Bless Texas ) I'm hoping I did the right thing getting 4.56's . Heading out the door to find out . They just came in . Time to get caught up on my "driveway" mechanics. Keep y'all posted . Keep on Jeepin Boys. B safe. Oh ! This buggy means the world to my lady . Like I say , I hope I did the right thing. This rig is in mint shape . The undercarriage is like new. Besides a bullet hole in the back panel , so is the top half.

[@jonarment1229]

How'd the 4.56's work out?

[@brendanlanigan6104]

I have a 00 4.0 5 spd with 33s and I’m pretty sure I have the same 3.07 ratio, I noticed that there’s really no difference city driving but on the highway it is a little more sluggish. You still get to speed it just takes a little longer lol

[@BipolarBear777]

True and same here 😊

Mine is Command-Trac Part Time 4WD System Dana 30/186MM Front Axle Heavy Duty Dana 44 / 3.73 Rear Axle Trac-Lok Differential Rear Axle 4-Spd. Automatic 42RLE Transmission 30X9.50R15LTB Wrangler OWL A/T Tires (in stock version) Driving 265/75 r15, which is almost 31" tires. Have bunch of ideas about mods, but due to tight budget had to put all of it on hold for now. I drew lots of "blueprints" about how do I like to see my bumpers, running boards, fenders, tire carrier, etc.

Sounds like a great place to start

[@Moto_x11]

2004 Tj 5 speed manual. I’m on 33s with 4.56 gears it’s a nightmare on the highway! Around town it’s good but the beginning gears are incredibly short. By 3rd gear I’m going maybe 20-30mph. On the highway in 5th gear I’m at 65mph at 2500 rpm tapped out.. I was on empty so fast and my engine wasn’t happy. I’m thinking 3.73 will be a better fit for me idk about 4.10s. I wrote this to help save time and money for the next guy as all the forms and my research pointed to 4.56 but I’m going to change gears again with only 500miles on my new gears. Last thing I’d recommend motive gears they are super quiet and well made in my opinion.

[@steveblankenship2413]

use your gps, / maps on your phone to tell how fast your going, to see how far your off on your speedo , 3.07 gears ,forget 5th gear on any kind of incline ,keep in mind also big tires and 3.07 gears is very hard on your trans synchronizes , also if ya regear spens the extra money to put a posi track in the back, big difference off road my regear was $ 4,500 that was all new everything

[@SmokinMonkeyOG]

Ya I’ve checked it with a gps that’s how I know it’s 10km/h off or about 6mph. Hope to find all news axles with higher ratio gears eventually

[@Ryan-Tanner]

Very helpful video. Thanks man. Was also wondering if i went up to 33s on my 4 cylinder tj and did not re gear, would it cause any engine damage??

[@SmokinMonkeyOG]

Thanks bro, engine damage no but you should check what gears you have. If it’s a 2003 - 2006 you have 4.56 gears which is perfect. If you have a 1998 - 2006 (I know they overlap that’s why you gotta check) you would have 3.73 gears which is still better than what I have but your automatic is what limits you. You will most likely have to get new gears but I could be wrong. Check to see if anyone on the forums or to tune has done 33s with their 2.5 auto

[@SmokinMonkeyOG]

Oh shit you didn’t even say automatic lol my bad. But ya if it’s auto it will be harder to drive than a manual if you don’t re gear

[@Ryan-Tanner]

@@SmokinMonkeyOG ok thanks. Yeah it’s an automatic. As long as it’s not causing damage I’ll probably go with 33s then re gear at a later time. Thanks for the help!

[@SmokinMonkeyOG]

Exactly how I’m feeling lol I can wait to re gear for a while too

[@GenVirtu]

Hey dude, just got my Jeep back from the mechanic this past week. My engine light came on two weeks ago. He checked it out and it turned out I needed a new catalytic converter. Among other things that my Jeep needed. it was so bad that it cracked the Exhaust manifold that was on my engine when I got it rebuilt. And yes it was expensive. 💸💸💸 Catalytic converter by itself was at least $1,000. 😩

[@SmokinMonkeyOG]

Ya it’s not fun when things break. Happy to hear you got it back up and running

[@JohnnaMartywashere]

I drive a 05 tj with a 6 speed trans, and 4.88 gears/ 33inch tires. I can tell you that my jeep has power for days, but its killing me on gas as a daily driver. Im running a dana 44 in the rear and 30 in the front and can tell that my engine stresses alot from trying to keep up at higher speeds. I read all the forums and watched all the videos and believed that i NEEDED 4.88 gears for my size tire, but turns out that thats only needed when offroading and doing trail stuff. I will be going to a 4.11 gear ratio which is a good balance of power, speed, mpgs and rpms....Some times I wish i never changed my gears and have been hurting for the last year... :(

[@SmokinMonkeyOG]

I have t changed mine yet but I have 3.07 with 33s and the 5 speed manual trans. Mine doesn’t have any power issues either I can drive it like a normal vehicle on road just don’t have amazing acceleration. Off road in low range you don’t even notice it. Drives mint. I might re gear but don’t feel the need right now. Might do it to take some stress off the driveline but it doesn’t seem to hate it lol

[@isachar2013]

What kind of jeep is that?

[@trevorturk7473]

1997 Sahara with 33x12.50 Yokohama Geolander MTs and stock 3.07 gears. I haven’t used 5th gear since I’ve bought the jeep. As soon as I shift to 5th, you notice a loss of power. The ratio just don’t sustain your speed. I do live in the foothills of the mountains so it’s very hilly and that has a lot to do with it. All the shops around here charge close to 2k for complete regear and at that cost I’m just gonna go ahead and do Dana 44s

[@SmokinMonkeyOG]

Ya the cost is similar here. I also have a lot of hills here and haven’t touched 5th in a long time but I’ve gotten used to it and don’t really mind too much

[@JoshPiercefield]

It's worth noting that this is only applicable to manual transmissions. If you have an automatic and go up in tire size, regearing is basically a must. Personally I went from 3.07 to 4.11 and could never go back.

[@tylercook3784]

I have a tj with a 350 SBC in it with 4.10 gears on stock tires and i need to get bigger tires soon... jeeps were not made to go this fast lmao

[@SmokinMonkeyOG]

Lmao 😂

[@craiginker6732]

I have a 2004 Manual 5 speed 4L. Front Axle is a Dana 30/186mm Rear axle is a Dana M35/194 mm 3.73 Rear Axle Ratio Any thoughts / references if I can go to 35's tires?

[@SmokinMonkeyOG]

If you upgrade the shafts to RCV in the front and something strong in the back then you should be able to run 35s as long you don’t go nuts on the throttle. But the limiting factor is the axles are not very strong from factory so they need a bit of work

[@pol1970]

Nice video and Jeep! Is that stock exhaust??

[@SmokinMonkeyOG]

Thanks! It’s a cut off shorty exhaust. No muffler

[@pol1970]

@@SmokinMonkeyOG awesome! Thank you!

[@bboymuggshott]

For 33s you’ll be fine on 3.07s. Just gotta be careful wheeling and accelerating aggressively

My jeep is on 31s with a 2.5 lift I have 3.73 gears and it accelerates pretty quick and I have to shift like im drag racing lol I dont know if I should stay with 31 or go up to 33s what do you think?

[@SmokinMonkeyOG]

I do think think you’ll notice much difference in acceleration from 31 to 33. I have 3.07 gears and drove on 31s for a year and went to 33s. Honestly didn’t notice much of a difference lol could be my gearing tho. If you go off road grab the 33s. But it will kill your gas mileage

[@robertsantana6462]

@@SmokinMonkeyOG I do off road but I think imma stay with 31s cause I do travel alot and it is a daily driver but thanks for the info!

[@SmokinMonkeyOG]

Ya I would stick with the 31s as well in that case. Maybe find a cheap used set of 33s down the line and use those for off road and have the others for daily use

It also depends if you’re driving into the wind or not. Lmao I know it stupid but the Jeep is shaped like a toaster. Some days I can do 100mph some days it won’t do 60mph lmao 🤣

Mine too, 31s and maybe with a little down hill help I can reach 70-74mph

@@SmokinMonkeyOG i forgot to put i have the automatic and the differential is a Dana 44 . Its a daily driver for me so if possible would regearing be a good investment

[@SmokinMonkeyOG]

Use the link in the description and find out what gears you have currently. Ideally with 33s you want around 4.27 or higher number gears. Mine has 3.07 so I need to re gear for sure but I have the manual with d35 rear end

Possibly the transmission gearing but I hear you it’s not great even with the TJ
