Key Features

Bilstein's 5160 Series shocks incorporate innovative features that set them apart from standard factory units. Crafted with high-quality materials and precision engineering, these shocks are designed to withstand the rigors of off-road driving while providing consistent, fade-free performance. The remote reservoir design increases oil capacity, which helps dissipate heat more effectively, reducing shock fade during extended use or aggressive driving. This results in a more stable ride and longer-lasting performance.

• Monotube construction ensures consistent damping and responsiveness under all conditions.
• Velocity-sensitive digressive valve settings are tuned specifically for each application, providing optimal handling and ride comfort.
• Remote reservoir with a high-pressure nitrogen charge improves cooling capacity and wheel travel, enhancing off-road capability.
• Heavy-duty mounting hardware and durable finishes resist corrosion and wear, even in harsh environments.
• Designed as a direct fit replacement, requiring no modifications for installation.
• Engineered to support lifted suspensions, maintaining proper ride height and handling characteristics.
• Offers improved wheel control, reduced body roll, and enhanced stability over rough terrain.

Construction & Design

The Bilstein 5160 shocks feature a monotube design with a robust, high-strength steel body and a remote reservoir that is connected via a durable hose. This configuration allows for increased oil capacity and superior heat dissipation, which is critical during demanding off-road use or towing. The shocks are TIG-welded for added strength and precision, ensuring a leak-proof seal and long-term durability. The external reservoir is equipped with a high-pressure nitrogen charge, which maintains consistent damping performance regardless of temperature fluctuations.

The internal valving is carefully calibrated for each specific application, providing a balanced blend of comfort and control. The shocks' design minimizes cavitation and fade, allowing for sustained performance during extended off-road excursions or heavy-duty hauling. The overall construction emphasizes longevity, with corrosion-resistant finishes and heavy-duty mounting components that withstand the elements and rough terrain.

Installation & Fitment

The Bilstein 5160 Series shocks are designed as a direct bolt-on replacement for the factory rear shocks on compatible RAM 1500 4WD models from 2009 to 2018. Installation is straightforward, requiring no cutting, drilling, or modifications. Basic hand tools and a lift or jack are sufficient to replace the existing shocks, making it a manageable upgrade for DIY enthusiasts and professional installers alike. Proper torque specifications should be followed to ensure secure mounting and optimal performance.

• Direct fit replacement for OEM rear shocks on 2009–2018 RAM 1500 4WD models.
• No additional modifications or tuning required.
• Installation typically takes less than an hour per side.
