Detailed Description

Arnott BAG-CH151922 is built for rear suspension support on Chevrolet Silverado 1500 and GMC Sierra 1500 applications where added stability is needed for towing, hauling, or changing cargo loads. The air spring design lets you tune support with air pressure, which helps keep the truck level and improves control during weight shift events. By softening axle-to-frame contact and reducing inner-leaf friction, this rear helper air spring kit helps preserve ride quality while maintaining braking performance under load. Arnott BAG-CH151922 is a direct-fit suspension leveling kit for 2019-2025 Silverado 1500 and Sierra 1500 models with in-bed hitch compatibility.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Rear sag when carrying cargo or towing
• Reduced steering control caused by rear-end weight shift
• Harsh axle-to-frame contact over bumps or under load
• Loss of ride quality from added payload weight
• Brake effectiveness changes during heavy-load operation

Installation Notes and Tips

Verify rear suspension layout and in-bed hitch compatibility before installation. Use the included mounting hardware and follow the vehicle-specific service procedure for air spring placement, air line routing, and final pressure setup. After installation, check for clearance through full suspension travel and recheck air pressure after the first load cycle.

Quality Assurance

Arnott BAG-CH151922 uses rubber bellows, a black bellows finish, and regular-grade construction for rear load support applications. Arnott’s air spring design focuses on adjustable support, ride control, and stable braking performance in towing and hauling conditions.
