The Bilstein AS2 Series 46mm monotube shock absorber gives racers an aluminum, rebuildable design that maximizes grip and enables precise ride height tuning.

You need reliable suspension to push your vehicle on the track. These Bilstein shock absorbers use a 46mm internal bore monotube design to deliver the grip you need for cornering. The hard anodized coating reduces internal friction while boosting overall strength under heavy track use.

• Heat Dissipation: The aluminum threaded body increases heat dissipation, keeping the shock stable during intense track sessions.
• Ride Height Tuning: The threaded design provides precise ride height adjustments when you pair it with coilovers.
• Added Grip: A specialized base valve assembly utilizes lower gas pressures to provide additional tire grip.
• Race Rebuildability: The rebuildable design lets you expand your tuning options with separately sold pistons and piston bands.
• Easy Fit: Measuring 29.5 inches long and 3.5 inches wide, this shock pairs easily with standard suspension mounts.
• Lightweight Build: The 7.0-pound weight helps keep your vehicle agile without adding unnecessary bulk to the chassis.

Swap out the old pistons and bands to customize your rebound characteristics for different track conditions.
