Built for Chevy and GMC 2500HD/3500HD owners who haul and tow — Rough Country's Rear Air Spring Kit levels your truck under load, reducing sway and bottoming out when braking and steering.

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 airbags with internal bump stops designed for 0–7.5" of adjustable lift on your 2500HD or 3500HD.
• Air Spring Spacer Kit — 4-inch spacer with 4-degree geometry correction to maintain proper suspension angles.
