I have been thinking about changing my 355's to 410's. And I wanted to see who has made the change ! My setup is 01' Sup. Crew, 5.4L, Auto on a 285/60/18 tire = 31.46" tall. This a Street truck and Family Transportor, Its not for racing but for towing the camper and getting everyone around. What kind of gas milleage do you think I will be at, and what RPM's verus MPH are some of ya'll doing ?

 

I have 4.10s in mine.
With a 32" tire at 70 to 75 I'm running about 22 to 2300 RPMs.

4.10s is one of the best things I've done to the truck!

Especially for a 2WD truck, best value to increase performance.

 

I have them on Mine 05 FX4 love them I running 20*10 rims and 305/55/20 Nitto TA

 

So what about the MPG ! How much more dis it increase ?

 

i have 35 bf all terrain with 4:10 blued (thats a process on the gears) The guy put them in year before i bought the truck.

I think it needs 4.56 or 4.88

I'm wanting (trying to find) a WIDE 33 or 35 inch tire
They don't make mickey baja in 17 inch rim style anymore and 16.5 don't fit (OR DO THEY) i really like the 33x14.5 or 35x17.5 style on the truck
