Zone Offroad is now offering leveling kits specially designed for the 2019 Chevy Trail Boss and GMC AT4 trucks. Engineered to be more than just a "budget boost”, these kits are designed to a higher standard to work within the parameters of the factory suspension and steering geometry to maximize its potential while allowing clearance for larger tires. As with all Zone Offroad lift kits, these new kits are backed by Factory Protection Plus for piece of mind wherever your adventures may take you. Factory Protection Plus includes Zone Offroad’s Limited Lifetime Warranty, ESC system compliance and a 5-year 100,000-mile drivetrain warranty.

Kit Features:

 - 3-piece design with top mount spacer and 2 preload spacers to raise ride height without over-extending suspension during droop travel.

 - Maintains ride quality and handling characteristics.

 - Allows clearance for 33-34” tires

 - Includes Factory Protection Plus.

When it comes to suspension and leveling kits, Zone Offroad knows their stuff. The newest addition for the 2019 Chevy Trail Boss and GMC AT4 truck platform are 1.75” leveling kits engineered to work within the parameters of the factory suspension geometry. The Trail Boss/AT4 trucks use a taller strut assembly for an increased ride height over factory Silverado/Sierra trucks. While others bolt on a tall top mount spacer to increase right height, the length of the strut assembly becomes too long causing premature wear of front end components. The engineers at Zone Offroad went a different route, a better route using a 3-piece leveling kit designed with a shorter top mount spacer so as to not overextend the suspension at full droop and combined that with a pair of preload spacers designed raise ride height without extending the overall strut length. The result is a level stance that retains the factory ride quality and handling characteristics without causing premature wear to suspension and steering components. With the full 3-piece spacer installed your truck will net 1.75” of front lift as recommended for AT4 models for a level stance. The Trail Boss doesn’t have as much factory suspension rake so not as much lift is required to level the stance. By not installing the second preload spacer the truck will net 1-3/8” of front lift which will level out the Trail Boss. Also included in this leveling kit is a pair of lower control arm steering stops. These optional weld-on steering stops will help eliminate clearance issues with some oversized tires on factory rims.
 All kits come finished in a durable black e-coating and sent with all the hardware needed to complete the install along with step-by-step installation instructions. All Zone Offroad kits include Factory Protection Plus for the ultimate extended warranty to include the limited lifetime warranty, ESC system compliance and a 5year-100mile drivetrain warranty to match the dealer. Improve the look and capability of your 2019 Chevy Silverado 1500 Trail Boss or GMC Sierra 1500 AT4 with the new 1.75” leveling kit from Zone Offroad.
