Bilstein B6 4600 Series Rear Shock Absorber (24-274944)

Upgrade the ride, control, and durability of your Super Duty with the Bilstein B6 4600 Series rear shock absorber (part number 24-274944). This direct-fit monotube shock is engineered as a high-performance replacement for the factory OE rear shocks on stock-height 2017–2026 Ford F-250 and F-350 Super Duty trucks. It delivers noticeable improvements in handling, stability, and comfort for daily driving, towing, and light off-road use without changing ride height.

Key Features & Benefits

Why Choose the Bilstein 4600?

Factory Super Duty shocks often wear out and lose damping ability, leading to a bouncy ride, poor control when towing, and reduced stability. The Bilstein B6 4600 restores and improves upon OE performance with a proven monotube design that stays consistent in heat and under load. Many owners report a noticeably smoother, more controlled ride that still retains the solid, truck-like feel expected from a Super Duty.

Note: Sold as a single shock. We recommend replacing both rear shocks at the same time for balanced performance.
