Detailed Product Description

The Rancho RS9000XL shock absorber is designed to meet the suspension demands of heavy-duty Ford trucks such as the F-250 Super Duty and F-350 Super Duty. With a compressed length of 18.93 inches and an extended length of 31.23 inches, this shock absorber provides a travel length of 12.3 inches, allowing for smooth suspension articulation. The inclusion of a dust shield helps protect internal components from debris and extends service life. The shock features an extended bumper stop to prevent damage during full compression, while the absence of a compressed bumper stop allows for controlled damping characteristics.

Mounting is facilitated by a loop bushing and sleeve lower mount with a 9/16 inch sleeve inner diameter and 1.5 inch outer length, paired with a loop bushing upper mount sized at 5/8 inch inner diameter and 1.3125 inch outer length. The reserve tube diameter of 2.751 inches supports consistent hydraulic performance under load.
