gear ratios
#1
#4
ya but it needs new gears cus i just shredded the old ones. so if im doing it anyway then why not change the ratio up? and my front driveline is broken so i never drive with it in. so then if i never use 4wd then couldnt i just change the rear gears then do the front when i get my driveline fixed?

With 40's and 3.54's you do not have a very good mix at all.
Yes,the torque of the Cummins will move the big tires but using torque instead of HP can and will break parts,as you have already found out.I'd say 4.56's with 40's would give you a nice highway driver but for all out brute force power displays you going to have to step up to at least 5.38's.
Below os a link to a chart I ALWAYS use when looking at new tires for my ride and what to consider with diameter changes......Hope this helps you out with your decision.....Andy
