Hope this is the right spot for this post. I'm trying to figure out what my gear ratio on my front axle is, I read if I have the tow package it's 4.10. Below is my build sheet, can anyone tell me what my ratio is?

Your Build Code DMFP states you have 4:10's. Your front & rear ratios are always the same.

 

The fact it has an automatic means it would have come with 4.10 gears.

 

4.10's. Says that's what is in your front and both axles have to match. If you have a tranny cooler and hitch its safe to say you have the towing package.

 

Great. Thanks for the quick replies. I'm a noob so didn't know both axles were the same.

When I go to 35's will I be good with this ratio then?

 

All depends on what type of wheeling you are doing with those 35's. Some here seem to think that combo is OK, some regear.

Street driving, dirt roads, easy mountain trails, even moderate mountain trails... you'll probably be OK with that combo.

You may have to put the auto tranny in 3rd if you are driving a lot of hills and the tranny keeps shifting back and forth.

Same with towing... lock out OD.

Hard core trails and rock crawling... better regear to 4.88's or lower and install a locker too.

Good luck and have fun!
