Bilstein M 9100 Coilover Shock Absorber - Nickel

 

The Bilstein M 9100 Coilover Shock Absorber is built for customers creating high-travel off-road suspension systems that need spring support and damping in one package. It suits lifted trucks, custom trucks, rock crawling, and off-road racing applications where travel, heat control, and chassis control are all priorities. The nickel plated finish gives the coilover a clean motorsports look for exposed suspension hardware.

A threaded body screw top coilover layout gives builders a way to package the spring around the shock body while keeping ride height and suspension movement tied together. The reservoir design increases oil capacity and helps the monotube damper maintain more consistent behavior under repeated hard use. That makes the M 9100 Coilover a serious choice for vehicles that see rocks, ruts, whoops, and high-speed compression events.

The grouped options cover 10 inch, 12 inch, 14 inch, and 17 inch travel choices, with 46mm and 60mm piston diameter versions represented. A 22mm shaft, spring seat included, and 1/2in heim mounts at both ends support custom off-road suspension planning. Customers can choose the travel range that best matches wheel travel, ride height, and chassis packaging.

This coilover format is valuable when customers need the damper and spring to work as an integrated unit. It can simplify custom suspension packaging compared with separate spring and shock layouts, especially on long-travel builds. The spring seat included in this group confirms its role in coilover suspension systems.

Because the M 9100 Coilover is a custom application component, careful measuring is essential. Builders should confirm collapsed length, extended length, spring clearance, reservoir routing, bump stop engagement, and tire clearance before installation. When matched correctly, it supports controlled suspension movement across demanding off-road terrain.

Whether customers are upgrading for high-travel coilover suspension, rock crawling, or off-road racing, the M 9100 Coilover Shock Absorber delivers reservoir-equipped Bilstein performance. Now Available at LEER!
