Description
Upgrade your light truck or SUV suspension with the Bilstein B8 8100 Bypass shock absorber, part number 25-326376. Designed as a direct-fit replacement for select Toyota 4Runner and Lexus GX460 applications, this motorsports-inspired damper delivers position-sensitive performance, improved ride control, and dependable bottom-out resistance. Its dual-tube external bypass design provides independent adjustment for compression and rebound, allowing drivers to fine-tune damping behavior for changing terrain and driving conditions.
The Bilstein B8 8100 uses Incremental Flow bypass adjusters with click-adjuster knobs for precise, repeatable tuning. A bottom hose and remote reservoir exit port help maintain consistent compression control through the full suspension cycle, while the included bolt-on anodized aluminum chassis mount supports a straightforward reservoir installation. The EVO Grey finish provides a durable, professional appearance, and the bypass body design is engineered for suspension performance rather than coilover use.
This Bilstein shock features double-adjustable compression and rebound damping, a monotube internal design, a 60mm piston, and an 18mm shaft. It uses a stem upper mount and 19.2mm eye lower mount, with an extended length of 24.09 inches and a collapsed length of 14.72 inches. The reservoir-equipped design is suitable for enthusiasts seeking greater control, comfort, and tuning flexibility on light-truck and SUV platforms. Verify vehicle configuration and suspension compatibility before installation.
Compatible applications include select 2012–2016 Lexus GX460 models and 2012–2016 Toyota 4Runner models. This product does not include a boot or spring seat. Installation should be performed using appropriate tools and procedures, with all mounting hardware properly secured.
