Since Ram's not on the ball here, I went to the parTs counter with the vin # of a offroad addition and compared the differences. So far the UCA is the same and the coil springs and shocks are different (F&R). Not sure about the rear suspension bars and the stability cntrl. So far for my v6 quad cab bighorn sport with v-6 it's stacked up to $1054 for springs and shocks on all 4 corners. Apparently the shock valving is set up more for off road, and is likely set up to sync with a longer travel, +2" up and down. With the 2" mopar kit it has spacers, UCAs better shocks ( fox or bilsteins) and something to do with positioning the stabilizer bars. The shocks are longer but not sure if you gain travel unless the springs don't bottom out before the shocks, but I doubt it. You need UCA's for a 2" lift so the geometry doesn't get screwed up running at a different height. Without this, the ball joints will get jacked. If to exceed 2" lift with the stock differential and cv joints, they will also get jacked. Now I'm not sure if the 2" lift is as good as the off road package. If fca doesn't put out the 2" lift I'm likely to have one option for my quad cab v6. Does anyone have the off road package on their DT? Any comments on the road handling? I also learned about the dynamic air dam, it has a slip clutch on it to prevent damage in case it drags. My final thought was using the 2" if and when it comes out , but use the longer springs with 1/2 thick spacers to get both full 2" heigth and the additional travel. Any thoughts on that?
