Detailed Description

The Dorman 949-356XD is an air suspension compressor engineered for 2013-2018 Ram 1500 applications with case. It is a direct-fit style replacement for vehicles using an electrical air spring system, and it addresses common compressor issues by replacing the wear-prone plastic piston with an aluminum piston and adding improved sealing for better resistance to moisture intrusion. The upgraded thermal classification also supports compressor durability under operating heat.

This part cross-references Arnott Industries P-3241 and OE number 4877128AA for the same application. For Ram 1500 air suspension repair, 949-356XD provides a focused replacement solution for compressor-related failures.

Common Problems This Part Can Solve

• Compressor failure caused by moisture intrusion
• Reduced air suspension performance from piston wear
• Slow or weak system pressurization
• Air suspension warning lights related to compressor output
• Loss of ride-height control in the suspension system

Installation Notes and Tips

Fits 2013-2018 Ram 1500, N/A, with case. Confirm the vehicle uses the correct electrical air suspension setup before installation. Inspect related air lines, connectors, and suspension components for leaks or damage so the replacement compressor is not overworked after service.

Quality Assurance

Dorman OE FIX components are built to address known failure points in original equipment designs. This compressor uses updated internal materials and sealing improvements to support reliable operation in the intended Ram 1500 application.
