Air Spring Kit | 5 Inch Lift Kit | Chevy/gmc 1500 (07-18 & Classic)

Built for Chevy and GMC 1500 owners who haul and tow heavy loads, this rear air spring kit levels your truck under load to keep your rig stable and safe. A 5-inch rear lift with up to 5,000 lbs of load support means your truck stays level whether you're towing a trailer or hauling cargo — no more sagging rear springs or uneven stance.

Installed and serviced at Road Runner Wheels & Tires. Most air spring kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• Air Spring Kit — Double convoluted air bags with reinforced powder-coated steel brackets and DOT-approved airlines, engineered to support up to 5,000 lbs and minimize trailer sway and bottoming out during braking and steering.
• Air Spring Spacer Kit (4 Inch, 4 Degree) — Positioning hardware that delivers the correct ride height and geometry alignment for your truck.

Important notes

• This kit does not increase towing capacity — it levels your truck under load for safer handling and reduced strain on your trailer's tongue weight.
• Minor drilling is required during installation.
• Onboard air compressor and wireless controller are optional add-ons — the base kit ships with manual air-fill capability.
