Im looking for some help on making a decision on some gearing for my 2003 3/4 ton 4X4 Hemi. When I ordered the truck I had the gearing changed from the 4.10 down to the 3.73 since I was doing alot of highway driving at the time. Recently I just installed 35" tires on my truck. I pull a 18' trailer and the tires made a drassic change for pulling. I added the Super Chip Programmer and it put my speedo back to stock and stiff-end the shift points some. I really would like to make this some what better then what it was before I changed the tires. I would really hate to go back to the stock tire size since the truck looks really great with these tires. I have spoke to a couple of people and they are recommending that I have 4.56 gears installed which will drop it back down to a 3.92 which would be better for pulling and better then what I did have. Is this true, and how do I fiqure out if this is correct. I was just wondering if other people have had the same issues, and what they have done to improve this. I do know that the Power Wagon has 4.56 gears but with 33" tires, would this drop it back down to a 4.10 which would be stock for a 3/4 ton, or would I still have to go to a taller gear to get it to a 4.10. Thanks
