Detailed Product Features and Specifications
The RS55066 shock absorber from Rancho's RS5000X line features a compressed length of 19.41 inches and an extended length of 28.59 inches, providing a travel length of 9.19 inches. This design supports a wide range of suspension movement, suitable for off-road and on-road conditions encountered by Jeep Wrangler vehicles. The shock includes a dust shield to protect internal components from dirt and debris, enhancing durability. Both upper and lower mounts utilize loop bushing and sleeve mounts, with the upper mount sleeve measuring 1/2 inch inside diameter by 2.75 inches overall length, and the lower mount sleeve measuring 1/2 inch inside diameter by 1.5 inches overall length.
