Bilstein B6 4600 Rear Shock for F-150
Bilstein B6 4600 shock absorbers are a direct-fit upgrade for stock-height light trucks and SUVs. This rear shock for the 2009-2013 Ford F-150 uses a monotube design and a velocity-sensitive digressive piston to maintain consistent damping as road conditions change.
Key Features
- Direct-fit replacement for OE rear shock applications
- Monotube internal design for consistent, fade-resistant performance
- Velocity-sensitive digressive piston reacts to changing road inputs
- Non-adjustable damping for application-specific tuning
- Blue bellows boot and yellow painted finish
- Eye 12mm upper and lower mounts
- No reservoir design
Product Details
The Bilstein B6 4600 line is tuned for specific vehicle applications to improve ride control, handling response, and comfort without changing stock ride height. Part number 33-187419 is built for the rear position on 2009-2013 Ford F-150 models and is engineered as a direct OE-style shock absorber upgrade. This part cross-references Rancho RS999384 for the same application.
Common Issues It Can Help Address
- Excessive rear-end bounce over bumps and expansion joints
- Reduced control during braking, cornering, or load changes
- Worn OE shock performance on a stock-height Ford F-150
- Inconsistent damping from aging twin-tube style shocks
- Harsh or unsettled rear suspension response on rough pavement
Installation Notes
Compatible With 2009-2013 Ford F-150, rear. Verify mount style, suspension configuration, and part number 33-187419 before installation. This shock uses eye 12mm upper and lower mounts, so confirm the vehicle’s rear shock attachment points match the listed hardware interface. Professional installation and a post-install suspension inspection are recommended.
