Detailed Description

Rancho RS80450B is a front coil spring kit engineered for 2003-2013 Ram 2500 and Ram 3500 trucks. It provides a 2.5-inch front lift to create additional clearance for larger wheels and tires while keeping the suspension geometry within the intended lift range for the application. The steel construction, shot-peened surface treatment, heat treatment, and powder-coated finish support consistent performance in demanding truck use. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
