Zone Offroad C69N 4" Suspension Lift Kit for Trail Boss & AT4

The Zone Offroad C69N is a complete 4" suspension lift kit specifically engineered for 2019-2023 Chevrolet Silverado Trail Boss and GMC Sierra AT4 4WD trucks. This innovative system is designed to work with the factory-equipped 2" strut lift found on these models, providing a net 4" increase over stock ride height. The final ride height achieves a similar stance to a standard GM 1500 equipped with a full 6" IFS lift kit.

Complete Kit Includes:

• High-strength crossmembers for enhanced durability
• Steering knuckles engineered for proper geometry
• Strut spacers to integrate with factory lift
• Upper control arms for optimized suspension travel
• Differential relocation brackets to maintain proper driveline angles
• All necessary hardware for installation

This lift kit provides clearance for up to 35" tires while maintaining factory ride quality and handling characteristics. The comprehensive design ensures proper suspension geometry and driveline angles are maintained throughout the vehicle's range of motion. Zone Offroad manufactures all components in the USA and finishes them with durable powder coating for long-lasting appearance and corrosion resistance.

Warranty Coverage: Zone Offroad backs this kit with a limited lifetime warranty on hard parts and a 3-year/36,000-mile warranty on wearable components including ball joints, tie rod ends, and bushings.

Important Note: Factory 17" and 18" wheels cannot be reinstalled due to tie rod end interference. Stock 20" wheels can be reinstalled. Aftermarket 17" wheels with 4.5" backspacing should be test fitted prior to tire mounting. Professional installation by a certified mechanic is strongly recommended.
