Detailed Description

Built from 5160H alloy and finished in metallic grey powder coat, Dorman 929-911 is engineered as a direct rear coil spring replacement for trucks used in continuous load-carrying conditions. The pigtail over center and semi-closed plain end design supports proper spring seating, while the constant-rate construction helps maintain consistent rear suspension behavior under load.

Inspect rear spring seats, isolators, and surrounding suspension components before installation. Verify standard-rate rear fitment for the specific Ram 1500 or Dodge Ram 1500 model year before ordering. After installation, confirm ride height and suspension alignment checks as needed for the vehicle’s load setup.
