Product Description

The Bilstein 25-320442 B8 8100 Series Rear Left Shock Absorber is a high-end suspension upgrade engineered for 2005-2023 Toyota Tacoma 4WD models, designed to work with stock suspension or trucks with modest rear lifts up to approximately 1.5". Featuring a large 60 mm monotube body with a remote reservoir and a dual-tube externally adjustable bypass design, this shock delivers exceptional damping control, heat management, and ride comfort both on and off the trail.

With independent rebound and compression bypass adjusters, the 25-320442 allows for precise tuning of suspension response from soft to firm, giving drivers the flexibility to optimize ride quality and control for their specific driving conditions. The remote reservoir increases oil capacity and enhances bottom-out resistance, while the direct-fit design and included hardware make installation straightforward with OE mounting locations. Note that 2024-2025 Tacoma fitment was unconfirmed at the time of listing, though many parts that fit 2023 continue into newer model years.
