Bilstein EM46 Series Shock Absorber

 

Bilstein EM46 Series Shock Absorber is built for customers who need a serious motorsports damper rather than a basic replacement shock. The emulsion design is aimed at racers who want a rebuildable shock with a straightforward package and a large shaft for demanding applications. 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 piston gives the shock a strong monotube foundation, while the smooth body layout keeps the package adaptable for race chassis mounting. For customers working with dirt, asphalt, desert, or mixed competition environments, that control helps the suspension respond with more consistency as conditions change.

The zinc-plated steel body, 22mm shaft, and high-temperature rod seal help the damper support repeated race use and setup work. 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 8.00 in and 10.00 in stroke versions with digressive dry kit setup details. 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.

EM46 dampers are intended for motorsports applications where the builder chooses the correct shock length, spring strategy, mount style, and tuning plan for the chassis. 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 race chassis setup, rebuildable shock service, or custom suspension tuning, the Bilstein EM46 Series Shock Absorber delivers simple emulsion-damper packaging with strong monotube control. Now Available at LEER!
