This Dorman leaf spring assembly is engineered to carry vehicle weight and payload while helping maintain suspension performance and passenger comfort. The 3800 load rate, 6-inch arch length, and 28.5-inch dimensions support rear suspension service on Ram 3500 models, while the 30.5-inch B dimension helps identify the correct application. Part number 34-1747 should be matched to the listed fitment and spring configuration before installation.
Common Uses

Installation Notes
Verify the rear fitment, 8-leaf configuration, and spring dimensions before installation. This assembly includes bushings, and mounting hardware is not included. Confirm that no axle modification is required for the application and compare the original spring attachment style to the Berlin eye and up-turned eye ends.
