Hi guys, i need your help. I have an 89 Bronco with an 8" Skyjacker Suspension lift as you can tell by my information. Anyways i'm still running 31's with the stock gear ratios. I need to know what size new gear ratios i need to push 35's without too much strain on my old 302 and sucking up all my gas. I have an AOD tranny if that helps. I've been told 4.10 and 4.56 gears and can't decide what to choose from. I need to know a good brand of gears to buy also. Any techniques on figuring out the new speedometer gear i need will also be greatly appreciated. Thanks for everyone's time! bye.
