Want to re-gear...4.10's?
Hey guys I have an 02'scab 2wd with the 4.6L. It has a spindle and leveling kit combo for about 5" lift...right now it has 265/70/17 but I am going to go to a 33 or 34 inch tire and want to regear to accomodate for it. Right now I have a 3.55LS and it does really good on the freeway but definetly needs more low end power! My question is I would like to try to get it back to stock with the 33's or 34's...so it should be a lot quicker than where I am right now with the bigger tires and original gears. I do mostly around town driving, I do tow a little, but I definetly do use it on the freeway too and I dont want it spinning at 3K RPM at 75-80mph. Basically looking for a noticable difference but I dont want to over do it either.

no, but i need to... i really don't have the $$$ to pay someone else to do it, and I want it done right... i'm researching it, and am going to probably do it myself. i am running 35'' BFG AT's, so they're not putting as much stress on my trans. as for example, a heavy 35'' mud terrain. i'm going w/ either 4.10's or 4.56's. 4.88's and my foot = <10mpg. it probably wouldn't be that bad, but this truck is staying my DD, and I am not going to upgrade to the 37-38's.
in the end, i will probably go w/ the 4.10's. the ratio will net me a realized 3.73 ratio, and i will be back in the stock powerband. i need to preserve my mileage as much as possible, as i already noted. i also have the 5.4, and some good power upgrades, so I don't feel I need to go as low as 4.56 or 4.88.

it has been so long since I drove the truck with stock gearing that I cant remember how much of a difference it was...I def. remember a noticable loss with my 265s, but this is prob because I have the 4.6L which doesnt have the most bottom end power. I think that the 4.10's will be very close to the stock setup plus I have a troyer tuner and intake and exhaust now so I think if I could get it back to stock with the bigger tires I am about to get I would be pretty stoked. 4.30 is interesting but I really dont want to over do it.
