Dorman 34-1709HD Leaf Spring Assembly - Rear

Leaf Spring Assembly for Heavy-Duty Rear Suspension

Dorman 34-1709HD is a steel leaf spring assembly built for rear suspension service on heavy-duty applications. It is engineered to help restore load support and ride control when the original spring has weakened or lost arch.

Compatible with Ram 3500 rear applications, this leaf spring assembly uses a 5-leaf design, a 3-inch leaf width, and a 3500 load rate. It includes black bushings and uses an eye-to-eye style attachment with one end in a Berlin eye and the other in an up-turned eye. Dorman 34-1709HD is a direct replacement-style suspension component for heavy-duty use.

Key Features

• Steel construction for suspension load support
• Heavy-duty suspension grade for demanding service
• 5-leaf design with 3-inch width
• Black bushings included
• Rear axle application with no axle modification needed

What This Leaf Spring Helps Address

• Sagging rear ride height from worn spring packs
• Reduced payload support under load
• Excessive rear suspension flex
• Poor ride control caused by weakened leaf springs
• Uneven rear stance from fatigued suspension components

Installation Notes and Tips

Verify the application details before installation, including rear position, load rate, leaf width, and end attachment style. This part includes bushings, and mounting hardware is not included. Because leaf spring fitment depends on suspension configuration, confirm the vehicle’s existing spring dimensions and attachment type before ordering. This part cross-references Monroe Shocks & Struts (e.g., 034-1709-00HD, 34-1709HDDAY) for the same application.

Quality Assurance

Dorman identifies this part by Spring Research Institute number 34-1709HD for application matching. The product is built as a heavy-duty suspension replacement for rear load-carrying service.
