Description
Upgrade your light truck or SUV suspension with the Bilstein B8 8100 Bypass suspension shock absorber, part number 25-326369. Designed as a direct-fit damper, this motorsports-inspired shock uses a dual-tube external bypass design to provide position-sensitive damping throughout the suspension cycle. Independent compression and rebound adjustment allows drivers to fine-tune ride control for changing terrain, vehicle loads, and driving conditions. The EVO Grey finish delivers a durable, professional appearance suited to demanding off-road and performance applications.
The Bilstein B8 8100 features Incremental Flow bypass adjusters with click-adjuster knobs for precise, repeatable changes. Its bottom hose and remote reservoir exit port help increase compression control through the full range of suspension travel, while the included bolt-on anodized aluminum chassis mount supports a clean and secure reservoir installation. The bypass body is non-coilover, and the shock is configured with a stem upper mount and 19.2-millimeter eye lower mount for compatible applications.
Engineered for improved ride comfort and bottom-out control, this Bilstein shock absorber combines a monotube internal design with double-adjustable compression and rebound damping. It is suitable for select Toyota 4Runner and Lexus GX460 applications from 2012 through 2016. Verify vehicle fitment and suspension configuration before ordering. The shock has a 14.72-inch collapsed length, a 24.09-inch extended length, an 18-millimeter shaft, and a 60-millimeter piston. Prop 65 Warning: Cancer and Reproductive Harm—www.P65Warnings.ca.gov.
