Important notes

• AT4X fitment only: This kit is designed exclusively for AT4X models equipped with the factory 2-inch lift and Multimatic DSSV dampers. Does NOT fit AT4X AEV models due to front skid-plate variances.
• Wheel requirements: Does not fit factory wheels. 20-inch or larger aftermarket wheels are required, with 4.5-inch backspacing. Some aftermarket wheels may require a 0.25-inch wheel spacer (part #1065). Test-fit wheels before installation.
• Tire clearance: Designed to accommodate 33–35 inch tires without additional modifications.
