What this part does
The Bilstein B3 rear air spring replaces the factory air bag on the rear axle of the BMW E61 Touring. It maintains correct ride height, supports self levelling, and restores smooth, quiet operation. Ideal when your rear suspension sags, leaks air, sits unevenly or the compressor is overworking due to a failing air bellow. The B3 air spring is designed for vehicles where the air spring and shock absorber are separate units, just like the original BMW setup.
