suspension upgrades

255-70-R15 on a 15x7 with 4.25 backspace with HD Springs fit real nice.
If you dont want to lift do 235-70-R15 on a 15x7 with 4.25 backspace and Stock replacement spring
As for traction you could do Calvert Racing's Caltracs.
Slapper bars (Traction Bars) dont work on Mopar that is what the pinion snubber is for.

Do thicker torsion Bars and the quad shock my buddy said it works good for what it is.
