BILSTEIN shock absorber (34-181577) restores factory damping characteristics by controlling spring oscillation on both compression and rebound strokes. Damping configuration is tuned to the original suspension geometry, preserving the manufacturer's comfort and handling balance. Mounting dimensions, piston diameter, and stroke length replicate the OEM unit on OPEL, VAUXHALL applications, allowing a straight-swap installation.
