Quick Overview

If you’re using your lifted Silverado or Sierra 2500HD, 3500HD for hauling and/or towing, this Rough Country rear air spring kit is just what you need to keep your truck level. This innovative upgrade provides up to 5,000 lbs of load support to reduce sway and bottoming out when either braking or steering. Without additional support, your truck will not sit level with additional weight in the bed or additional pressure from a trailer.


This innovative upgrade solves these problems giving you peace of mind when towing or hauling heavy loads. Included are two Rough Country branded high-quality double convoluted airbags that come equipped with DOT-approved airlines. Also included are ¼” push connector fittings along with all necessary bracketry to make installation lightning fast and secure.


IMPORTANT NOTE: Prior to purchase, take a measurement between the bump stop landing pad and the upper bump stop mount. This measurement range should be in the 10-1/4" to 11-1/4" lift range for proper fit. WATCH VIDEO
