Dorman 949-100 Air Suspension Compressor

Overview

This Dorman OE FIX air suspension compressor is a standard replacement for select Cadillac, Chevrolet, and GMC SUVs with thermal switch-equipped air suspension systems. Part number 949-100 addresses compressor overheating with an upgraded finned cylinder design that improves heat transfer and supports more consistent suspension operation.

Compatible With Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon applications that use the listed thermal switch configuration, this compressor is built for electrical air spring systems and direct replacement service. Part number 949-100 is engineered to replace a failed compressor without repeating the same heat-related failure pattern.

Key Features

• OE FIX design with an upgraded finned compression cylinder for improved heat dissipation.
• Transfers 25% more heat than the factory cylinder during compression.
• Thermal protection device and protective membrane add overheating defense.
• Standard replacement for 12V electrical air suspension systems.
• Black finish and 25 amp amperage rating.

Detailed Description

Dorman 949-100 is an air suspension compressor for select Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Avalanche 1500, Suburban, Suburban 1500, Tahoe, GMC Yukon, Yukon XL, and Yukon XL 1500 applications with a thermal switch. The compressor is designed around a finned cylinder that moves heat away more effectively than the original design, helping the unit stay within its operating range and supporting steadier air suspension performance.

This part cross-references Arnott Industries P-3242 for the same application. It is a practical replacement choice for owners addressing compressor failure, heat-related shutdowns, or uneven suspension behavior on Cadillac Escalade and Chevrolet Tahoe platforms. Part number 949-100 also includes thermal protection features intended to reduce repeat damage from overheating.

What It Helps Solve

• Compressor failure caused by overheating.
• Loss of air suspension pressure from a worn compressor.
• Inconsistent ride height control in electrical air spring systems.
• Heat-related damage that can affect downstream air suspension components.
• Reduced suspension performance on thermal switch-equipped vehicles.

Installation Notes

Compatible With the listed Cadillac, Chevrolet, and GMC vehicles only when equipped with the thermal switch configuration shown in the fitment data. Mounting hardware and mounting bracket are not included. Verify the electrical air spring system type, voltage, and fitment notes before installation.

Quality Assurance

Dorman OE FIX parts are engineered as upgraded replacements that address known failure points in the original design. Part number 949-100 uses thermal management features to improve durability in demanding air suspension service.
