Installation Notes and Tips

Verify connector style, mounting points, and OE cross-reference numbers before installation. This compressor assembly includes a mounting bracket, dryer, relay, and valve block, but mounting hardware is not listed as included. Because air suspension systems are sensitive to leaks and electrical faults, inspect the air lines, relay circuit, and related components during replacement to help confirm proper operation after installation.
