Arnott Industries Air Suspension Spring P/N:A-2501

$217.99

Description

Restore the ride height and cushioned ride of your BMW's air suspension with the Arnott Industries Air Suspension Spring A-2501 (also written A2501), a rear right air spring assembly that drops in as a direct-fit replacement for the 2000-2006 BMW X5. As the air spring ages, cracked or leaking rubber lets the corner sag and the compressor overwork — if a failed air spring is the cause, this assembly replaces it.

Vigorously tested: lab-verified and road-proven, developed in Arnott's research and development center through laboratory stress tests and real-world road evaluations.
Certified excellence: built under strict adherence to ISO quality standards.
Dual-continent expertise: produced at specialized facilities in the USA and EU.
Engineered for strength and durability to withstand demanding road conditions.

This is the rear right position; for best results Arnott recommends replacing air springs in pairs so both sides settle evenly. Always diagnose the cause of a sagging corner before replacing.
