Bilstein ASM Series Shock Absorber

 

Bilstein ASM Series Shock Absorber is built for customers who need a serious motorsports damper rather than a basic replacement shock. It is aimed at resto-mod and pro-touring customers who want a suspension damper that can bridge comfortable street use and serious handling demands. It is aimed at race builds, custom suspension packages, and demanding setups where damping control is a key part of how the vehicle puts power down and stays composed.

The design gives builders a durable foundation for dialing in ride control around track surface, chassis balance, tire package, and driver preference. The 46mm aluminum monotube body and threaded coilover-style design give builders a performance foundation for projects that need more control than a stock-style shock. For customers working with dirt, asphalt, desert, or mixed competition environments, that control helps the suspension respond with more consistency as conditions change.

The clear anodized aluminum body gives the shock a clean custom-build appearance, while heim mounts help the damper articulate in fabricated and performance suspension layouts. The finish and body layout are designed to support repeated service work, setup changes, and careful tuning without turning the shock into a disposable component. That matters for customers who maintain their own race program or work with a suspension specialist.

This range includes multiple stroke lengths from about 3.44 in through 7.93 in, with non-adjustable, single-adjustable rebound, and double-adjustable compression and rebound choices. Rather than forcing every build into one length or tune, the series gives customers a focused range of motorsports choices that can be matched around ride height, available travel, mounting points, and the type of control the chassis needs. The result is a shock absorber that can be planned as part of a complete suspension system.

ASM dampers are intended for custom performance applications where customers must match length, spring hardware, valving, and mounting details to the vehicle's suspension design. Customers should match the shock to the vehicle's suspension geometry, intended use, and sanctioning requirements before installation. Correct length, mount style, spring hardware, and tuning components are critical to getting the intended performance from this type of damper.

Whether customers are upgrading for pro-touring builds, resto-mod suspension upgrades, street performance driving, or custom coilover planning, the Bilstein ASM Series Shock Absorber delivers a controlled ride with motorsports-inspired handling capability. Now Available at LEER!
