I've got a '01 S-10 and I'll be installing 3" Bullseye lift spindles. I plan on running 31" BFG At/Ko tires on 15X8's. Is it necessary to re-gear from my stock ratio of 3.42? I'd like to maintain the performance as I will be towing my prerunner wherever I need to be. If this factors into the equation, it's a 4.3 liter V.6.
