Bilstein ASN Series Shock Absorber

 

Bilstein ASN Series Shock Absorber is designed for motorsports applications where lightweight construction, rebuildable service, and precise length matching are important. It is built for customers who need suspension hardware that can live in demanding environments while still giving builders the information needed to match the damper to a specific setup. The result is a focused upgrade for off-road, motorsports, and custom suspension projects where ordinary replacement shocks are not the goal.

The clear anodized finish and one-piece hard anodized body give the shock a clean racing appearance while supporting simple disassembly and repair. The design gives race teams, fabricators, and serious recreational drivers a damper that can be selected around ride height, travel, and mounting needs instead of forcing the suspension around a generic part. That flexibility is valuable on custom trucks, trail rigs, recreational off-road vehicles, and competition builds where packaging room and wheel travel both matter.

The group uses monotube construction, eye 12.7mm upper and lower mounts, no spring seat, and collapsed lengths from 10.45 to 15.08in with extended lengths from 14.21 to 23.60in. These details help customers compare the shock against their suspension layout before installation, especially when a build requires a specific collapsed length, extended length, mount type, or reservoir arrangement. Fitment is matched by the selected vehicle or custom application rather than by a universal promise.

Linear and digressive compression and rebound choices allow customers to select a damping character that suits the suspension setup, track terrain, and driver preference. Customers can focus on the length, travel, damping character, and mounting layout that support the way the vehicle is driven. A shorter setup may suit tighter packaging, while longer travel versions can help builds that need more suspension movement and more room to manage rough terrain.

In real use, the Bilstein ASN Series Shock Absorber is aimed at customers who care about control, serviceability, and repeatable suspension feel. It is a strong choice for builds that spend time on uneven terrain, in the desert, on rocks, around track terrain, or under a vehicle that needs more deliberate suspension tuning than an everyday replacement damper can provide.

Whether customers are upgrading for lightweight race builds, serviceable damper packages, or custom motorsports suspension tuning, the Bilstein ASN Series Shock Absorber delivers rebuildable suspension control with linear or digressive damping choices. Now Available at LEER!

Available Options

The Bilstein ASN Series Shock Absorber is available in multiple configurations:

• Digressive damping versions -- provide a digressive compression and rebound profile for racers who want a firmer response at lower shaft speeds
• Linear damping versions -- provide a linear compression and rebound profile for customers who want a more proportional damping curve
• Length range options -- cover compact through longer body lengths so builders can match shock movement to the suspension layout

Choose digressive damping for a firmer initial control feel, or choose linear damping for a more proportional response through shock movement.
