Sku : 66-3921

ReadyLIFT® customers have asked for it and we have delivered. In the fall of 2018, 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 is 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 ReadyLIFT 66-3921 1.75" leveling kit is similar to our popular 66-3086 leveling kit for pre-2019 trucks. The 66-3921 leveling kit provides the required amount of lift without causing conflict with the factory strut geometry and clearances. In light of the factory upper control arm's lack of dynamic range when the AT4/Trail Boss truck is further lifted, this leveling kit includes our popular tubular upper control arms with corrected ball joint cup angles, heavy-duty replaceable ball joints, and our new Terrain Control Technology (TCT) maintenance-free pivot bushings with side-biter washers to improve alignment retention.

Note: AT4 and Trail Boss do not fit the same size tire. This is due to the difference in the front fender opening design.

66-3921 Leveling Kit:

AT4 - Max tire 275/60-20, 20x9 0 offset wheel

Trail Boss - Max tire 295/65-20, 20x9 0 offset wheel

ROLLOVER HAZARD

MISUSE OF THIS PRODUCT COULD LEAD TO INJURY OR DEATH.

Modified suspensions and large-diameter tires that increase ground clearance will alter vehicle handling.

The vehicle may become more likely to roll over. Suspension systems or components that enhance the on and off-road performance of your vehicle may cause it to handle differently than it did from the factory. Extreme care must be used to prevent loss of control or vehicle rollover during abrupt maneuvers.

Slower speeds may be required to maintain control. Always operate your vehicle at reduced speeds to ensure your ability to control your vehicle under all driving conditions. Braking distance may increase. Failure to drive safely may result in serious injury or death to driver and passengers. Drive with extreme caution until the operator become familiar with how the vehicle handles.

Driver and passengers must ALWAYS wear a seat belt; avoid quick sharp turns and other sudden maneuvers.

Some modifications may be illegal in various states. Consult vehicle owner's manual, the instructions for this product, and state law before modifying any vehicle. Review all state and local laws, including but limited to, laws related to bumper height and the lifting of vehicles before the purchase and installation of any ReadyLIFT/ReadyAIR products.

Never operate your vehicle under the influence of alcohol or drugs.

Drive with extreme caution until the operator becomes familiar with how the vehicle handles.

Constant maintenance is required to keep the vehicle safe. Thoroughly inspect vehicle regularly, especially before and after every off-road use.

It is the responsibility of the driver to check the surrounding area for obstructions, people, and animals before moving the vehicle.

All raised vehicles have increased blind spots; damage, injury and/or death can occur if these instructions are not followed.

Drive with extreme caution until the operator become familiar with how the vehicle handles.
