I just had 35in. tires installed, and would like to improve on the sluggish performance. Motive gear makes a 4.30 gear for the ford 9.75. Would this be better for street and highway use, or would the 4.56 gear be the better choice?

 

Sorry for the double post, did'nt think the first one went through

 

where did you find 433 gears for our 9.75 inch? Thats why I havnt done gears yet I do a lot of highway (80mph) and 456 is to steep for me.

 

A company called riverside gear has them on their web site, they have a toll free number of 1-877-614-4327. The part numbers are also listed on motive gears web site. Riverside has them listed for 199.95. I found this company doing a search, it was posted by one of the members, can't remember who.

 

4.56s . .

 

with 35" i say 4.56

 

Does the gearing matter whether the 20's are running on AT's or MT's ... ?

I thought 4.88 was the way to go with 20X35... ?

 

If you want whiplash when you take off

 

4.56 would be best you wont regret it!

 

456 would put my RPMs at 80 at like 2800 or something my gear shop told me. I turn 2k at 80 right now with 35s and 373, what would I trun with 456?

 

how about with 37's? 4.88's??

 

Boy, I bet the gas companies love you

 

I run 35's and chose the 4.56's. Had the same debate as I run about 30k a year mostly highway. At 80mph you will run a hair under 2,400 rpm just as the gear calculators say. IMO 4.56's.
