Dorman 929-932 Coil Spring - Rear

Heavy-Duty Rear Coil Springs for Ram 2500

Dorman 929-932 rear coil springs are built for 2014-2025 Ram 2500 trucks that see continuous hauling, towing, or other demanding rear suspension loads. This heavy-duty spring set raises load handling capability by 35% over the vehicle’s nominal spring rate and adds approximately 1.9 in of OE lift for a firmer, more controlled stance.

Engineered from 5160H alloy with a powder-coated metallic grey finish, these coil springs are made for rear suspension service on Ram 2500 applications where ride control and load support matter. Dorman 929-932 is a direct-fit replacement for the rear coil spring position on the listed Ram 2500 model years.

Built for Heavy Rear Suspension Loads

Part number 929-932 is designed for Ram 2500 owners who need stronger rear spring support without changing the vehicle’s basic suspension layout. The variable-rate coil design helps improve ride quality, reduce driver fatigue, and sharpen handling when the truck is carrying sustained weight. This makes it a practical rear suspension upgrade for Ram 2500 trucks used in towing, hauling, plow service, RV duty, and other demanding work.

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

Common Problems This Part Addresses

• Rear sag from frequent heavy hauling
• Reduced ride control when the truck is loaded
• Excessive rear suspension compression under cargo weight
• Handling instability during towing or work use
• Worn or weakened original rear coil springs

Installation Notes and Tips

Compatible With 2014-2025 Ram 2500 rear suspension applications only. Verify spring seat condition, ride height, and suspension configuration before installation. Because seat hardware is not included, reuse or replace related components as needed based on the vehicle’s condition. After installation, check rear ride height and inspect alignment-related suspension angles if the truck has been carrying heavy loads.

Quality Assurance

Dorman suspension components are engineered for direct replacement use and built to meet the demands of service and repair applications. Part number 929-932 uses 5160H alloy construction and a powder-coated finish to support durability in heavy-duty rear suspension service.
