Key Features

• Heavy-duty front coil spring design for load-bearing suspension applications
• 35% increase in load handling capability over the original spring rate
• 5160H alloy construction with powder-coated finish
• Constant spring rate for predictable front suspension response
• Semi-closed plain ends and no spring seat included
• OE lift of +1.8 in for select applications
• Compatible with Ram 2500, Ram 3500, Dodge Ram 2500, Dodge Ram 3500, Silverado 2500, Silverado 3500, Sierra 2500, Sierra 3500, Express 2500, Express 3500, GMC G3500, and D350 front suspension applications

Detailed Description

This Dorman coil spring set is built from 5160H alloy and finished with a metallic grey powder coat for durability in heavy-service front suspension use. The constant-rate design helps maintain consistent ride height and steering feel under load, making it a practical upgrade for pickup trucks, SUVs, RVs, plow trucks, and vans that see frequent hauling. Part number 929-907 is a direct-fit suspension component for select front applications, including Ram 2500 and Ram 3500 models with leveling IFS, as well as several Chevrolet Silverado, GMC Sierra, Chevrolet Express, GMC G3500, and Dodge D350 configurations.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end sag from repeated heavy hauling
• Reduced ride control when carrying cargo or equipment
• Excessive suspension compression under load
• Unstable handling in work-truck or fleet use
• Need for a firmer OE-style front spring rate

Installation Notes and Tips

Verify exact vehicle fitment by year, make, model, position, and suspension configuration before installation. This spring set is for front applications only and does not include spring seats. Because coil springs store significant energy, use proper spring-compression tools and follow factory service procedures during removal and installation. Confirm ride height and alignment after replacement, especially on vehicles used for towing, plowing, or continuous hauling.

Quality Assurance

Dorman manufactures this spring set with 5160H alloy construction and a powder-coated finish for service in demanding suspension environments. The constant-rate design and OE-style fitment support consistent performance across the listed front applications.
