AutoWheelZone customers have asked for it and we have delivered. Last fall we announced our new leveling and SST lift kit offerings for the all-new GM 1500 trucks. We specifically did not include the factory lift kit-equipped GMC AT4 and Chevy Silverado Trail Boss. The AT4/Trail Boss are factory equipped with a 2″ front lift. This front lift includes a longer front shock/strut assembly. When combining a traditional leveling kit on these factory lifted trucks, several issues present themselves including binding problems with the factory control arm ball joint and contact concerns with the lower strut/CV axle assembly. The 69-3920 SST Lift Kit works with the factory 2″ front lift. This kit includes a top mount strut spacer along with a pre-load spacer to limit droop and the same premium grade upper control arms now available in our 66-3921 leveling kit. OE style 3″ tall cast iron rear lift blocks and rear bump stop extension cups are also included to create a true AT4/Trail Boss-specific bolt-on lift kit that provides 2″ of front lift and 1″ of rear lift. This new lift kit concept is similar to our successful TRD Pro Plus 2 SST Lift Kit which is also engineered specifically to work with that factory OE suspension lift. Your trust in AutoWheelZone to provide high-quality, precision engineered products is extremely important to us. You can be assured that this all-new SST lift kits are the absolutely most reliable and best performing suspension upgrade option for the AT4/Trail Boss trucks.
