Yes, please ditch the throttle body...they are a complete waste of time, not even designed for a vehicle with a fuel rail.[sm=icon_cheers.gif]

 

I believe that 4.10 gears would work well for your 33" tires. I have 4.56 gears on mine with 37" tires and it made a huge difference in the way it takes off, even before my other mods. Your transmission will thank you as well. As for the time it takes to change them, I opted to have 4wheelparts do mine in Tampa. It took them a day to do it. They also warranty their work so I felt is was best to have them do it. I replaced gears once before on an S-10 I once had and it didn't go so well. I messed something up when I did it and I don't know what. That is why I paid the extra $ to have professionals do it for me this time.
