A Suburban is a lot of truck to take out onto the trail, but that doesnt mean you have to settle for rolling around on stock tires. Most of the places we like to go on the weekends were tearing at our front air dam and reaching for our running boards. The low ride height (not our wife) was the limiting factor in where we could take the family four-wheeling. So when Tuff Country introduced its new 4-inch lift for 2000-and-newer Suburbans and Tahoes we had to check it out. Tuff Countrys kit is designed for trucks that have the new five-link rear suspension and retains the Autoride system. GM engineers spent a lot of time and money developing the Autoride system (91 pages of the factory service manual are devoted to Real Time Dampening). Tuff Country recommends a certified mechanic perform the installation, so we packed up our stuff and headed to PG Series new Hard Rock Cafelike facility in El Cajon, California, to have the lift installed.
