Can the 8.25 IFS handle a regear to 4.88?

My 97 has a 6" lift on 35s with 3.73s. Driving in hilly areas and/or pulling a trailer is just terrible...not much power at all.

I have the semi float rear axle so I'm not worried about its strength. I am concerned about the strength of the front diff having way deeper gears. I don't do any crazy wheeling and don't beat on it...mainly use the 4wd in snow, some sand, and some muddy trails. I don't go bogging in it because I want to keep it nice.

I'm going to regear to either 4.56 or 4.88 so I have some power with the 35s especially to help when pulling a trailer. Will the front diff be able to handle 35s and low gears? Who has done it before and had good or bad experiences?


I tried searching about 10 different phrases and searched the "stupid axle questions" thread. I found a lot of re gear recommendations and stuff but nothing specifically stating if the front diff could handle it.

Ive run 4.56 gears and 37" tires. Never did any serious wheeling. It will handle it. All depends on hp, traction and what your doin . Your more likely to break a cv axle over gears. Go with a quality gear like Yukon gear or motive. Get them set up correctly and you will have zero problems.

Great to hear that. I have a stock motor and don’t want to do anything to it except a full exhaust. Plenty of power for me I just want to be able to pull hills and tow better as well as daily driving with 35s. I can always get some CVs from the junk yard to keep as spares just in case. Thanks for the input
