Depends on how much you are willing to sacrifice as to what traction is possible.
You could reduce the # of rear leafs, put CalTracs on, and use air bags for heavy loads. This will keep the rear soft when you want it, and allow you to dial it up for towing or loads.
have to look at that. truck gets used for haulin quite a bit, so i need the load capacity. i know casper has fewer leaves. is it also runnin bags??
Tires? Wide and soft. Factory rims are narrow, so you are limited unless you are willing to swap rims.
how wide? 8"? 8.5"? bigger??? something light, i know that. does that mean keepin it 16"??
Basically you will want to run the kinds of tires listed above, the bigger the better, and to launch in 2nd gear.
if its an auto, how do i lock it out of first?? is there tuning for the tcm that will do that?? if so, can it be somehow hooked to a racing tune on a dsp switch so it will automatically lock out first when racing??
