Bilstein AS2-BV Series Shock Absorber is built for customers who need a serious motorsports damper rather than a basic replacement shock. It is designed for motorsports customers who want an aluminum threaded body damper with base valve technology and single adjustable rebound control. 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 monotube design combines with the base valve layout to support lower nitrogen pressures and grip-focused suspension tuning. 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 lightweight motorsports package, while 1/2in heim mounts help the damper move cleanly through suspension travel. 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 setup uses an 8.11 in stroke, single adjustable rebound control, and a threaded body that can be used with coilover hardware when the correct parts are selected. 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.
AS2-BV dampers are intended for custom race applications where customers confirm length, hardware, spring planning, and tuning details before installation. 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 grip-focused motorsports tuning, base valve setup work, or aluminum-body race shock upgrades, the Bilstein AS2-BV Series Shock Absorber delivers adjustable rebound control with base valve tuning potential. Now Available at LEER!
