Im getting some 4.56 gears (have 3.55s now) and i was just wondering what is was like to drive the truck with the new gears....anybody have any stories?

I have the 4.2 f150 5speed

 

but any stories are welcome not just v6 trucks

 

what size tire? my truck was still a dog with a 4.6 and 4.88s running on 35s. at least it moved out of its own way though.

 

i have 33x 13.50 and my truck pulls them just fine, i just haul to much and need more power for towing

 

with 40's and 5.38's the 4.2L can roast them.

4.56's and 33's you will have some low end torque

 

would it hurt to go to 4.88s, cause i tow alot and its heavy sometimes

 

With 4.88's and 33 inch tires, you will be running 2800 rpm in 5th at 70 mph. With 3.55's it's 2000 rpm and 4.56's it's 2600.

You DO know that the 5 speed manual is limited to towing 3500# because of a weak input shaft?

 

i will prolly just stick with 4.56s

 

definitely stick with the 4.56's unless you are running 35" of bigger tires
