Arnott Industries Air Suspension Spring P/N:A-2575
Arnott Industries A-2503 rear right air suspension spring for the 2000-2006 BMW X5 supports the vehicle's rear right corner on a rolling lobe air bellows. It is a standard replacement grade assembly.
A rear right corner that sits low, a rougher ride or a car that leans to one side can be signs of a worn air suspension spring. Those signs alone do not prove the spring is the problem, since a leaking air line can leave the corner sagging too. This listing is one spring for the rear right; the rear left is a separate part, and both sides are normally replaced together.
It fits the 2000-2006 BMW X5, which takes one on the rear right side.
