Product Description

The King Shocks 25001-393A is a bolt-on 2.5" OEM Performance Series rear coilover kit for the 2021-2026 Ford Bronco 4WD. Designed as a direct replacement for the factory rear struts and coil springs, this kit increases rear wheel travel, supports up to 35" tires, and adds adjustable ride height through a threaded coilover collar -- all without cutting, drilling, or modifying the factory chassis.

Each shock is built around a 2.5" diameter body with 6061-T6 aluminum construction and gas-charged at 150 PSI for consistent, fade-resistant damping. External finned remote reservoirs dramatically increase fluid and gas volume, accelerate heat dissipation, and maintain performance under sustained hard use. The included 20-click Wide Range Compression Adjuster allows precise damping tuning from soft daily driving to firm off-road terrain or heavy payload carrying -- all with a simple knob twist. Factory tuned using King's in-house dynamometer lab and real-world Bronco testing. Fully rebuildable, serviceable, and re-tunable. Backed by King's 90-day manufacturer warranty. Does not fit Ford Bronco Sport.
