I was very impressed with the mud grapplers. They clean out well and seem to always be pulling forward. I am defiantly going to have to re gear though around town it pulls them fine but extended highway it had a hard time finding a gear that it liked. So I spent a lot of time with the overdrive off.
Hows the lift holding up? I am thinking about selling all the blower conversion stuff to throw a lift on mine...
The zone lift is great. I can honestly say I have 0 complaints. The truck actually rides better now than it did before (I had the torsion bars cranked pretty hard).
