Suspension accessories in OE quality

The Bilstein B1 range covers top mounts (support bearings), protective tubes and bump stops, each matched to Bilstein shock absorbers, springs and suspension kits, plus the right compressors for Bilstein air suspension modules. Every part is made to uncompromising OE quality, so the whole suspension works as it should.

The B1 range at a glance

Top mounts, protective tubes, bump stops, decommissioning kits and compressors – each B1 service part is tuned to the suspension system it belongs to. The range covers nearly every vehicle model and keeps Bilstein dampers and springs performing well and lasting.

Matched to every Bilstein damper and suspension

B1 parts are more than accessories: they complete Bilstein shock absorbers, springs, air suspension modules and kits – from the B3 replacement spring up to the EVO R. Each one plays a key part in the performance and service life of the damper, spring or kit it is fitted with.

Product benefits

Small parts, big effect: B1 parts keep the whole suspension working and its quality intact, for lasting performance and the familiar Bilstein drive.

  • Matched to Bilstein dampers, springs, air suspension modules and suspension kits
  • Made for the exact model variant
  • Available for a wide range of makes and models
  • Genuine Bilstein service parts in top OE quality
  • Protects the function and service life of the whole suspension

What makes B1 stand out

  • A wide accessory range for almost every vehicle type, from small cars to SUVs and sports cars, tuned to Bilstein dampers, springs and kits for consistently balanced, safe handling.
  • Top mounts, protective tubes, bump stops and compressors in original quality – developed to OE specifications and tested to the same standards as original equipment.
  • Precise fit, so they install just like original parts, with no extra work or adjustment.
  • They complete the suspension down to the last detail and keep comfort, stability and safety for the long term.
  • Tested durability and OE-standard corrosion protection – made in Germany.
  • One compatible Bilstein system means less fitting time and less rework – good for service quality and cost.

The right part for every damper and suspension

  • For almost every model, from small cars to SUVs and sports cars: B1 top mounts, bump stops and protective tubes keep the whole suspension working smoothly, protected and precise.
  • OE replacement: ideal together with Bilstein B3 springs and B4 or B6 dampers for new-car comfort and safety.
  • Tuning: matched to Bilstein performance kits such as B8, B12, B16, EVO S/SE, EVO T1 and EVO R, for precise response and long life.
  • Top mounts link the damper to the body. B1 top mounts give precise response and wheel guidance and keep noise out; they are robust, accurately made and matched to each Bilstein system.
  • Bump stops cushion the end of long suspension travel and protect the damper from overload. B1 bump stops use a high-strength material that absorbs energy reliably and adds to safety and comfort.
  • Protective tubes shield the piston rod from dirt, moisture and stone chips, extending damper life and keeping damping consistent over time.
  • When a suspension without electronic valves is fitted to a car with electronic damping, the factory damper control has to be switched off with a matching decommissioning kit. B1 plug-and-play decommissioning kits stop error messages appearing after the suspension change.

Frequently asked questions

Do my shock absorbers need protective tubes?

Yes. Only a very few vehicles run dampers without them. They keep the environment away from the piston rod and seals, which would otherwise shorten the damper's life. If a damper comes without protective tubes, the OE-type tubes from the B1 range fit.

Do I need new top mounts when the shock absorbers are replaced?

Yes, always fit new ones with new dampers. Top mounts are safety-relevant wear parts that develop play or harden with age. New Bilstein top mounts restore precise wheel guidance, comfort and noise insulation, as on a new car.

Do I need new bump stops when the shock absorbers are replaced?

Generally yes. They cushion the end of heavy suspension travel and protect the damper and strut from mechanical overload. They become brittle or deformed with age, and worn bump stops reduce comfort, stability and safety.

When do I need a decommissioning kit?

When a mechanical sports suspension or coilover kit is fitted to a car with adaptive damping. The B1 decommissioning kits switch off the electronic damping control and prevent error messages in the car's electrical system.
