Detailed Description

Arnott BAG-CH159906 uses air spring support to add rear suspension capacity without changing the vehicle’s basic suspension layout. The rubber bellows and regular-grade construction provide load-bearing assistance that can be adjusted to match changing payload conditions. This makes it a practical choice for drivers who need more control from the rear suspension on a Chevrolet Silverado 1500, GMC Sierra 1500, or Ford F-150.

Compatible With 2007 Chevrolet Silverado 1500 Classic, rear; 2007 GMC Sierra 1500 Classic, rear; 1999-2006 Chevrolet Silverado 1500, rear; 1999-2006 GMC Sierra 1500, rear; 1997-2003 Ford F-150, rear; and 1999 Chevrolet Silverado, rear. The part number BAG-CH159906 is also a useful reference when verifying the correct rear helper spring kit for these applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
