Anbody know how to figure out what rear gears I have on my 01 supercrew 4x4 with the 5.4? I don't have the sticker from when it was new. Someone told me it sounded like I had 3:31's after I said that it runs about 2000 rpm's at 75 mph in overdrive. I guess that means that I can't do much about going up in tires from the P265/70/17 ones that are on it now without changing the gears, which I don't really want to do. Is there a tire that would be a little wider while keeping the same height so that I could keep the same wheels and not change the gear ratio? Discount said I could go to a 9" wheel, or go to a tire like a 285 something.

 

look at the axle code on the inside of the door and post it here.

 

What kind, where and how much for that light bar BigBadRedLiftedFordMan?

 

Axle code is H9. I knew somebody out there would iknow something.

 

19 = 3.55 open
H9 = 3.55 LSD
26 = 3.73 open
B6 = 3.73 LSD
27 = 3.31 open
18 = 3.08 open
25 = 4.10 open
B5 = 4.10 LSD

 

Thanks, APT. That eases my mind a little bit. That's beter than the 3.31. Does that mean I could probably go to a 285 size tire instead of the 265?

 

I have a Supercrew 5.4L 3.73 rear end with 285/70R17 and wish I had stuck with 265/70. Power loss, ride quality (of the BFG LT laod rating), and fuel economy have suffered. But, they look good and that's what counts, right?

 

Are you on the stock wheels? I like to see what the 285's look like. I need the economy and ride, though. How much different did the 265's look? I'm wondering about going to a little wider wheel (8"or 9") to get the wider look with the same tire. Not even sure you can run 265's on a 9 inch wheel. I currently have Michelins on it that I love and they don't have many miles on them. (7500?).

 

Click me or the WWW below any of my posts. Click on each picture for a little larger. I don't have any pictures on-line of this truck with the 265's as I only had them for 3 days. My last truck as a 99 Supercab with 17" wheels and I prefered the Revos I bought for that truck more than these BFG's. Also, I suspect the suspension is stiffer on this truck than my 99.
