I upgraded my shocks on all 4 corners with Bilstein 6112 and 5160. Always wanted to do that and at 75,000 miles on it had it done. Also upgraded skid plate and put on a heavy duty Coachbuilder shackle. That along with new Cooper ST Maxx tires and it was doing stuff on our elk hunt last week that really impressed me. Rides great as well. Might be worth looking at since the OP drives them for a long time like I do.

Only thing I wish mine had was the larger fuel tank.
