The Skyjacker Black MAX Shock Absorber B8559 is designed to provide dependable damping performance for select 1970–1974 Ford F-100 and 1987–1992 Jeep Wrangler applications. Its twin-tube construction increases fluid capacity, while advanced foam-cell technology helps maintain consistent performance as operating temperatures change. This design supports reliable control during daily driving, towing, hauling, and off-road use.
The foam-cell insert compresses to accommodate oil expansion when the shock absorber becomes hot, helping preserve MAX performance across a broad operating temperature range. By eliminating air inside the shock body, the foam-cell design also allows the shock to be mounted in any direction. Select-specific valving is engineered for application-focused handling, ride control, and suspension response.
Arc-welded end mounts provide durable attachment points for long-term service, and the Skyjacker Black MAX construction delivers practical performance and value for replacement or suspension upgrade projects. With a collapsed length of 16.560 inches, an extended length of 28.750 inches, and 12.190 inches of shock travel, this shock absorber should be verified against the vehicle’s suspension configuration before installation. Professional installation is recommended when required by the vehicle or suspension setup.
