Part #: B8389

Overview

The Skyjacker Black MAX Shock Absorber is engineered to deliver superior rear suspension performance for Jeep Wrangler JL and Gladiator models from 2018 through 2024. Designed specifically for vehicles equipped with engines ranging from the efficient 2.0L Turbo and 3.0L EcoDiesel to the powerful 3.6L V6 and 6.4L 392 HEMI, this shock absorber supports a 3.5 to 4-inch lift, enhancing off-road capability and ride quality.

Built for Jeep enthusiasts who demand reliable, consistent damping under all driving conditions, the Black MAX shock absorber combines advanced twin-tube technology with increased fluid capacity and innovative foam-cell inserts. This ensures optimal shock performance even during intense off-road use or extended highway driving.

Key Features

The Black MAX Shock Absorber incorporates several advanced features that set it apart from standard shocks:

• Increased Fluid Capacity: Enhances heat dissipation for consistent damping performance.
• Foam-Cell Technology: A unique foam-cell insert compresses to compensate for oil expansion when the shock heats up, maintaining consistent performance across temperature ranges.
• Air-Free Design: Eliminates air inside the shock, allowing for versatile mounting positions without performance loss.
• Arc-Welded End Mounts: Provides superior durability and strength for rugged off-road conditions.
• Vehicle-Specific Valving: Tailored valving ensures optimal ride comfort and control for Jeep Wrangler JL and Gladiator applications.
• 3.5-4 Inch Lift Compatibility: Perfectly matched for lifted Jeep suspensions to maintain proper geometry and handling.

Construction & Design

The Skyjacker Black MAX Shock Absorber is constructed with high-quality materials and precision engineering to withstand the rigors of off-road driving. Its twin-tube design increases fluid volume, which helps reduce heat buildup and shock fade during extended use. The foam-cell technology inside the shock absorber replaces traditional air chambers, preventing aeration and ensuring consistent damping performance regardless of mounting orientation.

Arc-welded end mounts add structural integrity, making these shocks highly resistant to damage from impacts and rough terrain. The valving is carefully selected to balance comfort and control, providing a smooth ride on pavement while maintaining firm support off-road.

Installation & Fitment

Installation of the Skyjacker Black MAX Shock Absorber is straightforward for Jeep Wrangler JL and Gladiator owners with compatible lifts of 3.5 to 4 inches. These shocks are designed as direct replacements for the rear suspension, requiring no major modifications or special tools. Proper fitment is ensured for models equipped with 2.0L Turbo, 3.0L EcoDiesel, 3.6L V6, and 6.4L 392 engines from 2018 through 2024.

For best results, professional installation is recommended to verify correct torque specifications and alignment, ensuring optimal shock performance and vehicle safety.
