Doing some upgrades to my TJ, looking for some input

[OlewhiteTj]

I am about to make a 1400 mile trip to Colorado in my Tj and I was looking for some input on re gearing my axles mostly because I wanna replace them and still have decent off road use but not 8 miles to the gallon. I have 33x13.50 tires and a 3 inch lift Thanks very much !! Any advice is appreciated !!

I was looking for some input ...

We'll be looking for some info. Engine, transmission, tire size, differential gear ratio, etc.

It's advisable to fill out your profile when asking questions so members know where you're starting from.

We need to know what engine and transmission you have .

A regear won’t decrease mileage..it usually helps it, because it corrects the balance of engine output to the driveline.

Also, you want to break them in before the trip .

Keep us posted, the answers you need are here.

See this thread for the correct gear ratio:

What gear ratio should I install in my Jeep Wrangler TJ / LJ? (and other re-gearing FAQs)

Don't regear and then head out on a long range trip. You want to be certain that everything is right and broken in properly first.

Sorry about that fellas I have the 3 speed transmission and a 4.0 engine stock gear ratio rn that I know of.

I’m seeking information individualized for my Jeep I have read that forum thanks

Do you know what your current axle and gear ratio are? If it’s a Dana 35 it will have a rubber fill plug in the rear of the housing if it’s a Dana 44 it will have a screw in plug. Either will have the gear ratio stamped on a metal tag held on by the cover bolts.

That is information individualized for your Jeep. Gear ratios depend on what engine, transmission, and tire size you have. That thread has a table in the first post with all of the individual options such as transmission, tire size, and engine.

Never tried them, but you can run the REM gears from Revolution, which aren’t supposed to need a break in process.

Lots of questions here, how does it perform currently? Are you just taking a road trip to Colorado or is there wheeling involved? If your TJ came with a 32RH 3 speed transmission and optional 30” tire group from the factory it will have a Dana 44 and 3.73 gears, which in my opinion would be fine for highway speeds (2500 rpm @ 65 mph), 2750 rpm with 4.11/4.10 gears with 33” tires it gives you the same performance as the Jeep engineers had for the 30” tire group, and 4.56’s would be perfect for short trips and wheeling but I wouldn’t want to drive 1400 miles on the interstate at 3250 rpm +

Thank you guys for all the input my axles are stock Dana 35 in the rear

 

[OlewhiteTj]

I’ll be living out there but driving back and forth from Atlanta to Denver often

I wouldn’t say it performs poorly but it’s time to upgrade. I want to do what makes the most logical since I have 33x13.50 on a 3 inch lift Dana 35 rear axle and well be driving highway a fair amount would really just like to replace my axle shafts with revolution and regear to what ever makes most logical since

Wow, that's a wide tire!

Wow, that's a wide tire!

I like em thick

 

[DrDmoney]

4.10’s is what is recommended.

You only need to put ~500 controlled miles on new gears to break them in (or 0 miles on Revolution gears with REM surface treatment). That's plenty of time if you get the work done in the next month or so.

You wont "like em thick" commuting that kind of distance. Regardless of what gear ratio you end up with that wide of a tire is GOING to kill your fuel mileage. They are extremely heavy and MT's are not the best idea for commuting as they create a LOT of drag. I realize looks matter to a lot of people but I would suggest going with a narrower A/T tire for commuting back and forth. Think 10.5 or 11.5 wide...
