Dorman 929-903 Coil Spring - Front

Dorman 929-903 Heavy-Duty Front Coil Springs

Dorman 929-903 is a front coil spring set for Ram 2500 and Ram 3500 trucks that need higher load support than the nominal spring rate. Built from 5160H alloy with a powder-coated metallic grey finish, these constant-rate springs are engineered for heavy hauling, towing, and other demanding front-end load conditions.

• Part number 929-903 for Ram 2500 and Ram 3500 front suspension applications

Detailed Description

Dorman 929-903 is built for pickup trucks, SUVs, RVs, plow trucks, vans, and other vehicles that operate under continuous heavy hauling conditions. The spring design focuses on improving ride quality under load, reducing driver fatigue, and maintaining more stable handling when the front suspension is carrying extra weight. For buyers searching for front coil springs for a 1994-2010 Dodge Ram 2500 or 1994-2010 Dodge Ram 3500, or a 2011-2013 Ram 2500 or 2011-2013 Ram 3500, this part provides a direct heavy-duty upgrade path. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Front-end sag from frequent towing or hauling
• Reduced stability when carrying heavy loads
• Harsh or inconsistent front suspension response under weight
• Driver fatigue caused by poor load control
• Need for a stronger front spring rate on Ram 2500 and Ram 3500 trucks

Installation Notes and Tips

Verify front suspension fitment by year, make, model, and standard-rate application before installation. Because spring replacement affects ride height and suspension geometry, inspect related front suspension components and confirm alignment after service. The OE lift listed for this spring set is -1.5 in, so final ride height should be checked after installation on the vehicle.

Quality Assurance

Dorman engineers this coil spring set for heavy-duty service using 5160H alloy and a powder-coated finish to support durability in demanding front suspension use. Part number 929-903 is built for consistent spring rate performance in confirmed Ram 2500 and Ram 3500 applications.
