Anybody have an idea on how much it might cost to change my gears from 3.73 to 4.10??? I've come to the concensus that if I want to maintain performance w/ 35's, I should get 4.10's for all that extra rubber? Anyone get this done and have a ballpark price?

 

all depends if you are 2WD or 4WD

 

35's = 4:56 gears

bigger than 35's = 4:88 gears

4:10s won't help ya much. If your going to spend the money and go to all the work get 4:56's.

 

Agreed. Re-gearing to 4.10's from 3.73's is not worth it. If you started with 275's on 18" wheels (32" tire"), regearing to 4.10's with 35's brings it right back to stock ratio. If you started with smaller tires, you are even worse than stock after changing to 4.10's. You need extra gearing to help make up for the added rolling mass, extra width, extra drag, etc.
Typically parts and install average around $600 per axle. That's a rough number but around $1100-1300 for a 4x4 truck is pretty normal. Install is not something a backyard mechanic should do, only an experience gear shop.

 

Gear installation is not THAT complicated, if you can read, follow directions, and have the patience(and $) to acquire the correct tools and use the appropiate methods of install. A back yard mechanic can make it happen. They do it all the time

 

^^^^

I agree it's not rocket science...

Buy you have to be good at that kind of thing.

 

Idk i had a friend who had a lifter 99 F150 4x4 with a 5.4 lightning swap..he was running 35s and went from stock gears to 4.10s in the front and rear and that thing was nasty.. he was putting down something in the neighborhood of 500hp

 

sounds like the supercharger is the one to thank , not the gears lol



i agree with efuehrin , go with 4.56. make it worthwhile

 

^^^^ I was thinking the same thing.
