Detailed Description

Dorman 929-920 is a rear coil spring replacement engineered for pickup trucks, SUVs, RVs, plow trucks, vans, and similar vehicles that operate under continuous heavy hauling conditions. The 5160H alloy spring design, 0.687 wire diameter, and constant-rate construction are selected to improve load support while helping reduce rear-end sag and maintaining more controlled handling under weight.

What It Helps Address

• Rear suspension sag from frequent cargo or towing loads
• Reduced stability when the truck is carrying weight in the bed
• Harsh or inconsistent rear suspension response from worn springs
• Loss of ride height at the rear of the vehicle
• Handling imbalance caused by tired factory coil springs

Installation Notes and Tips

Verify rear standard-rate fitment before ordering. Inspect related suspension components, including shocks, mounts, and isolators, during spring replacement so the new coil springs can perform as intended. Because spring replacement affects ride height and suspension geometry, a post-installation alignment check is recommended where applicable.

Quality Assurance

Dorman suspension components are engineered as direct replacement parts with application-specific construction and finish details. Part number 929-920 is built for rear service on the listed Ram truck applications and follows the brand’s focus on fit, function, and durability.
