Product Description

The Rancho RS994047A RS9000XL rear adjustable shock is engineered for the demanding rear suspension requirements of 2017-2025 Ford F-250 and F-350 Super Duty 4WD trucks. With a 9-position adjustment knob, this shock allows you to fine-tune the ride firmness to match towing, hauling, off-road use or stock driving conditions.

Built with a large-body monotube/tri-tube design, nitrogen-gas charge and integrated mount construction, the RS994047A delivers improved control, reduced shock fade, and long-term durability. The dual-component 2K finish protects against corrosion and impact damage - critical for heavy-duty truck environments. Direct-bolt mounting makes installation straightforward without extensive modification.

Ideal for Super Duty truck owners replacing rear shocks who expect enhanced performance under load, heavier tire/wheel setups, or mixed on/off-road use. Fitment is confirmed for model years 2017 through 2025 for the F-250 and F-350 4WD platforms. For best results, replace both rear shocks at once and perform a full alignment check after installation.
