My 93 f350 has 410 gears in diff how hard will be to put 355 gears in rear

Thanks

 

Are you planning on changing the front as well

 

Not sure what you mean

 

Is it a 4x4 and are the differentials Danas? Also are you thinking of doing this to improve fuel mileage?

 

No 4x4

 

3:55 = Good for driving on the interstate, and cruising around.

4:10 = Good for towing/pulling heavy loads.


Which one do you do most?

 

355 highway

And yes mileage I got plenty of power

 

As far as the switch goes, 3.55 is almost like driving a different truck, you would suffer a little bit if you lived in mountainous areas like I do, but not to bad. Usually people who get 11-13 mpg switch from 4.10 to 3.55 and see 17-19 mpg on these bad boys. They say towing will suffer as well, but I don't think so. I'm looking to do this swap as well. Be sure to do a write-up as you go!

 

Yes, it is going to b a couple of weeks. I have lots of different things going on. But will let ya no.........

 

Looking forward to seeing it done, what other modifications have been done to your truck
