I want to regear my Suburban. What's everyone's opion on gears? I've looked at the gear selection chart on 4WP's web page and they put me at 5.13's. I want to run 38" Super Swampers. I do some towing of other peoples fullsize trucks and my own fair share of wheelin. I was thinking that this gear ratio will take a lot of stress off the rest of my drivetrain and help my tired 350. My tranny is a T400 and my T-case is a NP241. Right now I have 3.73's with 36's and I spend a lot of time in low off road. I'm not worried about going over 70 mph. Is this too much gear? What are the cons?
