What model do you have? I have a 95 auto with 3.42 gears, iam thinking of going to a3.73 or a 4.10. But i am concerned that the fuel shut off would kick in at 78 or 88mph instead of 98 mph. 4.10 would be a rocket inthe 1/4 mile, but might wind on the highway.
If you do alot of highway, forget it if mileage is a concern. It'll KILL it. If you got a 4 cyl or an auto (or both), I'd say go for it. Otherwise, I think money can be spent elsewhere.
I had 4.10s but got rid of them for 3.73s, they were too much for me, would always break the tires loose and I use the truck for long drives so the 3.73s were the better way to go. It may be ok for your application tho because youre not pushing as much power..
I'm debating on whether to get 4.10's or 4.56's. I really want 4.56 gears but I already have 4.10s in my front axle im putting in the truck. BTW I will be running 35" tires, I think 4.10's might be a little too slow of a gear for a 2wd with small diameter tires.
