Several dealers are actually attempting or have been involved in the aftermarket/customization of jeeps via the dealership.. True Adams is but one and is prob the best or well known.. Jones Junction, Tate are others are fast approaching this type of off road market place.. I can't say I like any of them.. Thou some have contacts us in respects to our jeep and wanting to do things for us.
If your buying a jeep right out of the box.. you should consider one of those dealerships mentioned above.. but if your doing a few simple add-ons.. I would seek out an independent shop with experience in these types of installs.. or even a jeep club. Groups of volunteers would do the simply spacer install or better on any given weekend.
