Detailed Description

This Dorman 929-919 coil spring set is built for front suspension applications that see continuous hauling, towing, or service-duty use. The heavy-duty spring rate is tuned to improve load control and handling while helping reduce driver fatigue on vehicles that spend long periods under weight. It is a practical replacement for worn front springs on Dodge B350, Dodge D350, Dodge B300, and Dodge D300 models within the listed years.

The spring uses 5160H alloy steel, a 0.937-inch wire diameter, and a constant-rate design to deliver consistent suspension behavior. The 16-inch height and squared-and-ground end configuration support stable seating in the front suspension. This part number, 929-919, is a fitment-based solution for owners searching for a front coil spring replacement for 1975-1994 Dodge van and truck applications.

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

Common Problems It Can Address

• Front-end sag from repeated heavy hauling
• Reduced load control under cargo or service equipment
• Excessive body movement from weakened original springs
• Poor ride consistency on work-oriented vehicles
• Handling instability caused by tired front coil springs

Installation Notes and Tips

Verify front suspension fitment by year, make, and model before installation. Inspect spring seats, isolators, and surrounding suspension components for wear before reassembly. Because coil springs store significant energy, use proper spring-compression tools and follow service procedures during removal and installation. For search relevance, this front coil spring replacement is commonly sought for Dodge B350 front suspension repair, Dodge D350 front suspension service, and Dodge B300/D300 heavy-duty front spring replacement.
