Choosing The BEST Axle Gear Ratio

How to choose your axle gear ratio.
Axle gear ratios can be complicated and choosing the right ring and pinion can be hard. It certainly doesn't help that this is a big investment for most of us, so how do you choose the best ratio? In today's video we look at multiple ways to make sure you are buying the right gears for your axles and we even discuses if it's time to make the jump to a larger axle. This topic is complicated and the internet has more opinions then facts. Let me help get you the information you need so you can choose the right gear set the first time. Enjoy the video! Good luck!

Nate with the whiteboard is a killer combo. Thanks to guys like u and OverlandBound i been slowly getting more into wheeling, just yesterday i took my dad and nieces into a valley near my house :D

Hi, Nate, I was watching an early video from Bleeping Jeep days and you were talking about useing a drill press as a mill .well this is posable .the only thing you have to watch out for is the size of and depth of your cut. A drill press is set up for down pressure, were as a mill is set up for side, and down pressure . it will still wear the bearings at a faster rate but you can do it .I have done this .the feed rate is also a factor. I was aa machinist for 40 years, and in a pinch you have to be creative .I just thought i would lend my opinion .

I found that a horizontal bandsaw is the way to go. You can do so much more with a bandsaw than a 14" circular saw. The only disadvantage is the initial cost. I love your channel. It is good to see a regular guy build quality stuff without having a half million dollars worth of equipment in his shop. Keep up the good work.

I like to do it like building a barn if u think u need 24×30 build 32×64 if u think u need 4.88s go 5.13s cuz when u think u need 37s ur probably gonna go 40s 🤣

[messix]

Thank you again Professor Nate! another clear and concise informative video. one of the best that i have seen on this subject.

[anthonygendron]

I just 5.13 everything. My Yukon my Gladiator my old just feels better on and off-road.

[robormiston]

I like my 5.29's on my 35's on my 93 4 runner. In fact I might go to 5.71 unless I can get something in the 5.55 area. I have Yukon thick, 5.29 gears. But the guy who rebuilt my rear end and installed my Eaton E locker said I should use 4.88 and showed me a 5.29 pinion that was shredded and said that the 4.88 was the strongest gear in a Toyota rear end. It makes good power for a 3.0 in town I'm at about 3000 rpm for 35 mph driving. And it will, do 75 mph at 3500 rpm so not to bad. But can hardly use 5th gear. Makes a huge difference in how powerful the rig feels.

Yo Nate, Great job! Your explanation was better than anyone who has every tried to help me understand these things You rock!

[motoristx]

Awesome video on gearing calculations! I ended up reviewing what I’m currently running, with this process, just to see if it matches up with what I had done earlier this year. Keep up the good work, and keep using that whiteboard!

BMW have a diesel option, look for M57 diesel it is 6 inline 3l that makes decent power with some tunes, you can find it on the X5 335d

[DS-rjdb]

Thanks for the info...I double checked my gear selection form a 3.73 on 32's to 4.56 on 35's is the perfect selection (rounding up). Which gets me a bit over for not only the 35's but also I get that little bit extra for towing when needed.

[cynimaddict]

My TJ is an 02 X with an 05 Rubicon underneath. 4.0 with 5sp manual and 35s. The 4.10s feel great once up to speed and putting down the highway but man getting up there takes awhile and 1st gear takes a lot of throttle to get going. Really thinking about going to 4.88s if not 5.13s.

[reedcalder]

Good to see you doing your own thing thank you i learn about carrier deck height today keep up the good work

[jasonadrianr.garciajr.]

Running 3.73s on 33s on my TJ (4.0, AX15) does alright, is a little of a dog, but after I get my 8.8 under and chromolys upfront I’ll run 4.88s, elockers, along with 35s. I have a generally good idea about what I’m doing but I still really enjoy all the knowledge and research that goes into and out of your posts !

[cedargroves]

I finally got the answers I was looking for. Great video. Thanks!

[seanbenson]

The one exception to carrier break is the ford 9” same carrier for all gear sets. Got to love it strong simple to set up, there is a reason they have been and will be the axle of choice for drag racing for years.

[davidmcduffie]

IMO, I thought you did a very good job of explaining how to figure what gear ratio you need when installing bigger tires !!! I am in agreement with you. I would rather have a ( rounding up ) lower gear ratio ( higher numerical number ) because it has less strain ( demand ) on the engine. Enjoyed the video !

[TheSartorious]

I'm glad you made and I watched this video! You did basic answer a question I was Dwelling over this weekend in regards to deck height/gear thickness.

[willyoung]

I have 5.38 gears in my Suzuki samurai with stock axles and I can honestly say the pinion is downright adorable lmfao. Kinda makes me nervous wheeling it on 33s. Thankfully I have a Wagoneer d44 and an 8.8 to replace them soon

[kirkdunn]

Makes sense to me and am not a mechanic by any with tools building for living but not autos

Very well explained and common sense prevails once again
