Bilstein M Series Shock Absorber - Yellow

 

The Bilstein M Series Shock Absorber is built for racers who need a lightweight monotube damper with straightforward tuning choices. It is aimed at stock cars, IMCA and UMP Modifieds, midgets, mini-sprints, modified lites, and dwarf cars. The yellow finish gives the shock a classic Bilstein race appearance while the steel body supports the demands of dirt and asphalt competition.

A 36mm monotube design helps deliver consistent damping behavior when the suspension is working through fast transitions, corner entry, and uneven track conditions. The M Series is offered with multiple valve settings, allowing customers to match suspension feel to car weight, track grip, and driving style. That range gives race teams a practical tuning path without changing to a more complex damper package.

The grouped M Series options use an 8 inch stroke with 13.90 inch collapsed length and 21.89 inch extended length. Eye 12.7mm mounts at both ends make the layout familiar for many motorsports chassis. The shock can also support coilover conversion when the right kit is used, which gives customers flexibility across multiple race platforms.

This shock is especially useful for racers who want consistent handling and control in a durable package. The available valving identifiers let customers choose a compression and rebound balance that fits the car and the track. That makes the M Series a practical option for tuning corner attitude, drive-off grip, and overall chassis feel.

Customers should think of the M Series as a focused racing component rather than a street replacement part. The value is in its simple body design, clear length data, and multiple damping choices. For race cars that need repeatable feel and easy setup planning, the M Series keeps the damper package direct and useful.

Whether customers are upgrading for dirt track tuning, asphalt racing, or lightweight motorsports control, the M Series Shock Absorber delivers consistent damping with race-ready adjustability through valving choice. Now Available at LEER!
