Bilstein B6 4600 Rear Shock Absorber

The Bilstein B6 4600 rear shock absorber is a direct-fit upgrade for stock-height light trucks and SUVs that need more controlled damping than a worn OE unit can provide.

Product Line Details

The Bilstein B6 4600 series is built as a direct-fit suspension shock absorber for stock-height vehicles. This line focuses on application-specific tuning, using a monotube layout and digressive valving to deliver stable rear suspension control on everyday roads and uneven surfaces.

Fitment

• Fits 1983-2011 Ford Ranger, rear
• Fits 1994-2009 Mazda B4000, rear

What It Helps Address

• Excessive rear-end bounce over bumps
• Reduced control from worn factory shock absorbers
• Harsh or inconsistent ride quality on stock-height suspension
• Rear suspension instability during braking and cornering
• Loss of damping consistency from aging OE shocks

Installation Notes

Verify rear fitment by year, make, and model before installation. This shock uses eye-to-eye mounting with a 16mm upper eye and 12mm lower eye, so confirm the mounting points match the vehicle before ordering. This part cross-references Rancho RS999126 for the same application.
