BobInDenver and I were talking last night about mini-truck build costs.
If you want bigger tires, it is $5000
Bigger tires $1000
lift kit to clear bigger tires $500
regear to compensate for bigger tires $1000
While you are re-gearing, might as well ARB those diffs. $2500
There ya go. tires are $5000 to do it right the first time.
Add an SAS on that, don't forget the high-steer, and moving the steering box, and the ram assist, and the bigger steering pump, and the oil pan to clear the front diff...yep. $10,000
