Detailed Product Description

The Arnott P-3724 air suspension compressor assembly kit is a critical component for maintaining the air suspension system's performance on Mercedes-Benz R-Class models such as the R350, R320, R500, R550, and R63 AMG. Operating at 12 volts, this compressor delivers a maximum pressure of 185 PSI, sufficient to support the vehicle's air springs. The included dryer helps prevent moisture buildup, which can cause premature system failure. The mounting bracket and relay are included to facilitate installation, while the absence of mounting hardware and valve block means these parts must be sourced separately if needed.

Common Issues Addressed by This Compressor
