Re: Utah 4x4 shops
For sliders I would give Rocky-Road a shout. Some folks think that they aren't as stout as the others due to them not having as many attachment points. I HIGHLY recommend them (they are located in Heber). My old Jeep XJ had a pair (with only two attachment points) and they were without a doubt worth every penny. I beat the ever living crap out of the sliders and they never bent/etc or were an issue with the unibody construction of the XJ.
For MT tires, I never had much problems with BFG MT KM2's, but there are some great, aggressive AT tires that work well (probably better) for typical Utah road conditions.
All the mods and vehicles I have ever owned.
Anything less than absolute overkill is a half assed waste of time.
