Bilstein B6 4600 Series Rear Shock Absorber – 24-185981

Upgrade the ride, control, and durability of your Super Duty with the Bilstein B6 4600 Series rear shock absorber. This monotube gas-pressure shock is engineered as a direct-fit replacement that delivers a noticeable improvement in handling, stability, and comfort without changing ride height.

Key Features

• 46mm monotube design – Superior heat dissipation and consistent, fade-free damping under load
• Velocity-sensitive digressive piston – Instantly reacts to changing road conditions for better control over bumps, dips, and uneven pavement
• Application-specific valving – Tuned specifically for Super Duty rear suspension characteristics
• Yellow powder-coat finish with blue protective dust boot
• Eye-to-eye mounts (16mm upper / 12mm lower) for straightforward bolt-on installation using factory hardware
• Collapsed length: 18.04" | Extended length: 29.70"
• Sold individually (two required for a complete rear set)

Benefits You’ll Notice

• Reduced rear-end bounce and hop when empty or lightly loaded
• Improved stability and control when towing or hauling
• Smoother, more composed ride on daily roads and rough pavement
• Longer service life compared to worn factory shocks
