Well, after reading all the differing posts, which I truly appreciate, I ended up finding a set of 3.25 final gears for free. So I took out my 3.50 gears. I had to pull an axle anyways to repair a leaking axle seal. cleaned up the 3.25's, put in a new pinion seal, and swapped them out. (F@rd 9" by the way) I figure the best thing to do is to try the change and judge for myself, for my situation, with my setup, on my road conditions, with my driving style. It is an extremely cheap and easy trial, so why not. Now I only have to wait for the summer to show up. With several feet of snow on the ground and temps in the -30F degrees below zero, I just can't see myself going for a test spin!
