Product Description

Bilstein B8 8100 DSA is an adjustable remote-reservoir shock absorber built for lifted trucks and SUVs that need stronger control over rough terrain. It uses a large 60mm shock body and 2.65-inch outside diameter architecture to increase oil volume and help manage heat during long-distance, high-load suspension use.

Dual Speed Adjustment click knobs allow independent low-speed and high-speed compression tuning, so the ride can be tailored to surface conditions. The monotube design, velocity-sensitive digressive valving, 60mm piston, and remote reservoir make this a serious upgrade for drivers who want comfort without giving up control. Its direct-fit layout keeps the install cleaner than a fabricated race package.

This SKU is a rear left shock absorber. The listed applications also include a wheel-backspacing requirement.
