Air Spring Kit w/compressor | 3-5 Inch Lift Kit | Chevy/GMC 2500HD/3500HD (20-26)

Turn heavy-duty towing and rugged payloads into a controlled, confident ride with Rough Country’s Rear Air Spring Kit for Chevy/GMC 2500HD and 3500HD trucks (2020–2026). This system adds adaptive rear air springs that level the chassis under load and during towing, delivering a steadier stance from the cab with precise control you can dial in on the fly.

Why this kit stands out

• Dual double-convolution airbags deliver progressive, durable load support that adapts as weight shifts during hauling and braking.
• DOT-approved airlines ensure reliable, safe connections for long hauls and daily use alike.
• Onboard compressor puts ride height and firmness adjustments at your fingertips, without leaving the driver’s seat.
• Complete bracketry and 1/4" push connector fittings enable a streamlined, bolt-on installation using common tools.
• Load support up to 5,000 lbs helps minimize sway, reduce trailer tongue weight effects, and prevent bottoming out during braking or cornering.
• Designed for 3-5 inch lift setups so it complements mid- to moderately lifted rigs while keeping rear geometry balanced under load.

How it benefits your truck and towing setup

• Level loads, safer handling: keep the bed and trailer in a level plane, improving braking stability and steering response when pulling heavy trailers or carrying tall payloads.
• Reduced sway and trailer hop: extra rear support minimizes sway during lane changes, crosswinds, and sudden maneuvers, giving you more control on the highway.
• Consistent ride quality: the system adapts to load changes so your daily drive stays comfortable, even with a heavy bed or full trailer behind you.
• Simple air management: with the in-cab compressor, adjustments happen quickly—perfect for switching from unloaded to fully loaded without leaving the seat.
