I have 35 inch mud grapplers and wanted to know how much of a difference it will make going from stock gears on my FX4 to 4.56 gears?

 

A lot

X3

 

Good enough for me, just was asking cause one buddy said It would basically just improve my gas mileage, but I figured changing gears should help give the truck a little more pull, thanks for the input

 

HUGE....put's it close to stock again.

 

To add a little more to what I mentioned previously.....lol. You should notice better performance all around, including gas mileage... Good luck and enjoy...

 

what would i cost roughly to have my gears changed front and rear if i paid someone to do it?

 

I've seen quotes from 1500-2000. But that for parts and labor

 

If you know your way around the garage and a few precision tools, save your $$ and do it yourself...

It's not as hard as everyone makes it out to be... Especially with these axles...

It is not a job for the novice mechanic but it can be done in a home garage... With only a few special tools...
