What is the benefit of a remote reservoir shock absorber?

A remote reservoir holds extra shock oil, which increases the shock's oil capacity. This allows for greater heat dissipation, helping to prevent performance fade during extended use, especially in demanding off-road conditions.

What kind of valving does this Bilstein shock use?

This shock absorber features self-adjusting deflective disc valving. This type of valving reacts immediately to changes in the terrain, helping to optimize vehicle control and provide a consistent ride.

What is included with this shock absorber?

The Bilstein B8 5165 shock absorber comes with a remote reservoir and features 5/8 inch eyelets with hourglass bushings on both ends. It also includes a unique 360-degree swivel banjo hose fitting.
