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

Upgrade your heavy-duty pickup with the Air Spring Kit designed specifically for Chevy/GMC 2500HD/3500HD trucks (2020–2026). Built to work with a 3-5 inch lift, this system keeps the rear end level under heavy payloads or when towing, delivering a steadier ride, sharper braking, and confident handling—no more sag, sway, or uncertain feel when the load increases.

• Two double-convoluted airbags paired with DOT-approved airlines deliver dependable, responsive load support and level control as you load up.
• Up to 5,000 lbs of load support to minimize rear-end squat, reduce trailer tongue weight, and maintain stable steering and braking when under heavy load.
• 3-5 inch lift compatibility works with your existing setup to preserve ride quality while providing reliable leveling when payload or trailer weight increases.
• Comprehensive installation hardware includes 1/4" push connector fittings and all required bracketry, enabling a fast, secure retrofit without hassle.
• Level-focused design helps keep the trailer level, protecting your hitch, reducing sway, and delivering a more predictable, confident drive.

Why this rear air spring kit stands out

This isn’t just a suspension upgrade—it’s a dynamic, payload-responsive solution. The air springs adapt to changes in weight, so your truck maintains a level stance whether you’re loaded for work, heading to the job site, or returning home after a long haul. Expect less chassis squat, reduced sway during braking and cornering, and a more controlled feel across varying road conditions.

Ideal use cases

• Hauling tools, equipment, or bulk materials in the bed and needing consistent ride height.
• Towing heavy trailers where maintaining level ride reduces trailer sway and improves braking response.
• Operating with a 3-5 inch lift kit while preserving stock-like stability under load.
