Construction & Design

The Bilstein B8 5100 shocks feature a robust monotube construction that ensures consistent performance under demanding conditions. The monotube design allows for better heat management compared to twin-tube shocks, reducing fade during extended use. The shock body is zinc plated to resist corrosion, extending the service life even in harsh environments.

Inside, the velocity-sensitive digressive piston dynamically adjusts damping force based on road input, providing a smooth ride on pavement and firm control on rough terrain. The smooth body design and precise engineering make these shocks a reliable upgrade for lifted Ram 3500 trucks.

They fit trucks with 2 to 3-inch rear lifts that do not have air leveling suspension systems. No special tools or modifications are necessary, making it a convenient upgrade for DIY enthusiasts and professional installers alike.
