Product Details

Arnott P-3724 is engineered for Mercedes-Benz R-Class vehicles that use rear leveling and do not have front air suspension. This compressor assembly is a direct OE-style replacement for Mercedes-Benz part numbers 2513201204, 2513202004, 2513202404, 2513202604, 251320120428, and 251320260480.

• Slow suspension response or delayed ride-height correction
• Air suspension warning light related to compressor performance

• Noise, overheating, or intermittent compressor operation

Installation Notes

Verify the vehicle is equipped with rear leveling and no front air suspension before ordering. Confirm OE part number match and inspect the air lines, electrical connector, relay circuit, and mounting points during installation. Replacing a worn dryer and checking for leaks in the suspension system can help protect the new compressor from premature failure.
