Dorman 929-949 Coil Spring - Front

Dorman 929-949 Heavy-Duty Coil Springs

Dorman 929-949 front coil springs are built for Ram 2500 and Ram 3500 trucks that see continuous hauling, towing, or other high-load use. This suspension upgrade increases load handling by 35% over the vehicle’s nominal spring rate while helping improve ride control and reduce driver fatigue.

Key Features

• Heavy-duty coil spring design for front suspension use
• 35% higher load handling capability than the nominal spring rate
• Constant spring rate for predictable front-end support
• 5160H alloy construction with powder-coated finish
• Semi-closed plain ends for OE-style spring seating geometry
• OE lift of +3.2 in for added stance and clearance
• Fits 2013-2018 Ram 2500, front standard rate
• Fits 2013-2018 Ram 3500, front standard rate

Detailed Description

Built from 5160H alloy and finished in metallic grey powder coat, Dorman 929-949 is engineered as a front coil spring replacement for heavy-duty Ram applications. The constant-rate design helps maintain consistent suspension response under load, while the increased spring capacity supports vehicles used for plowing, RV hauling, commercial service, and other demanding duty cycles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end sag from repeated heavy hauling
• Excessive suspension compression under load
• Reduced ride control on work trucks and tow vehicles
• Driver fatigue caused by unstable front suspension behavior
• Handling inconsistency on Ram 2500 and Ram 3500 front suspension setups

Installation Notes and Tips

Install on the front suspension only and verify standard-rate application before ordering. Because spring replacement affects ride height and alignment, a professional alignment is recommended after installation. Confirm OE lift and suspension geometry before final assembly on Ram 2500 and Ram 3500 models.

Quality Assurance

Dorman engineers this coil spring pair for heavy-duty service applications using 5160H alloy and a constant-rate design to support repeatable performance in demanding front suspension use. Part number 929-949 is built to meet the needs of Ram 2500 and Ram 3500 trucks used in continuous load-carrying conditions.
