Bilstein B8 8100 Bypass Rear Left Shock Absorber 25-320442 for Toyota Tacoma 4WD

Bilstein B8 8100 (Bypass) is a direct fit, position sensitive, damper for light trucks and SUV’s. These motorsports inspired shock absorbers utilize a dual tube externally adjustable bypass design. B8 8100 (Bypass) feature “Incremental Flow” bypass adjusters, allowing for finite and incremental changes for rebound and compression. The shocks utilize a bottom hose, remote reservoir exit port, delivering increased compression control during the full cycle. The remote reservoir is supplied with a bolt-on aluminum anodized chassis mount for an easy fitment. BILSTEIN B8 8100 (Bypass) will maximize the driver experience, offering unparalleled ride comfort and incredible bottom out control. 60mm Shock Absorber

• 60mm large bore hard anodized aluminum piston offers a greater range of damping control and delivers exceptional long-term durability
• Dual tube external bypass offers position sensitive damping with independent adjustment for rebound and compression
• Incremental flow adjuster offers finite and incremental changes in damping force for precise adjustments

Upgrade the suspension performance of your 4WD Toyota Tacoma with the Bilstein B8 8100 Bypass Rear Left Shock Absorber, part number 25-320442. Designed as a direct-fit replacement for select Tacoma applications, this motorsports-inspired damper combines position-sensitive control with precise external adjustability.
