Bilstein B8 6112 Rear Suspension Kit
47-325593 combines two 60mm rear shock absorbers with matched cold-wound coil springs and billet aluminum spring seats. Vehicle-specific tuning and digressive pistons provide damping control on the road and over rough terrain. This is a rear-axle spring-and-shock kit, not a front leveling kit or complete four-corner system.
Application coverage
Bilstein's exact-part catalog lists selected 2021–2026 Ford Bronco applications. Coverage is trim- and year-specific, not every Bronco in that span:
- Badlands: 2021–2026; 2025–2026 rows exclude HOSS 3.0
- Base: 2021–2023 and 2025–2026
- Big Bend, Black Diamond and Outer Banks: 2021–2024
- First Edition: 2021
- Wildtrak: 2021–2022
- Heritage Edition and Heritage Limited Edition: 2023–2024
Confirm exact trim, door count and factory suspension package before selecting the spring-seat setting. Bronco Sport and Bronco Raptor are not among these listed applications. Do not assume compatibility with HOSS 3.0 or other unlisted configurations.
Included components and rear lift
- Two B8 6112 60mm rear shocks with two matched cold-wound springs: rear lift depends on the factory package, door count and circlip setting as detailed below.
- Two billet aluminum spring seats, with spring-seat isolators and supplied flange lock nuts identified in the installation instructions.
Bilstein's B8 6112 chart specifies the following typical rear heights with the supplied Bilstein springs. Circlip positions are numbered from #1, the lowest groove, through #6:
- Sasquatch package: #1 0.3 in, #2 0.5 in, #3 0.7 in, #4 1.0 in, #5 1.2 in, #6 1.4 in.
- Badlands without Sasquatch: #1 1.2 in, #2 1.4 in, #3 1.6 in, #4 1.9 in, #5 2.1 in, #6 2.3 in.
- Four-door without Sasquatch or Badlands, not equipped with factory yellow Bilstein ESCV shocks: #1 1.8 in, #2 2.0 in, #3 2.2 in, #4 2.4 in, #5 2.6 in, #6 2.8 in.
- Two-door without Sasquatch or Badlands, not equipped with factory yellow Bilstein ESCV shocks: #1 2.0 in, #2 2.2 in, #3 2.5 in, #4 2.8 in. Do not use positions #5 or #6.
The exact catalog's general non-Sasquatch trim rows summarize 2.0–2.8 inches; the installation chart distinguishes four-door and two-door settings. Use the vehicle-specific chart, not a universal lift range. These are typical heights relative to the relevant factory configuration, not guaranteed measurements on every vehicle. Do not use the separate B8 6100/OE-spring chart for this 6112 kit.
Assembly and original-component reuse
This is not a preassembled coilover pair. Professional assembly with a suitable spring compressor is required. Use the supplied Bilstein springs for B8 6112, and reuse the OE jounce bumper and OE top-hat assembly, including the top mount plate and spring isolator, only if serviceable.
Discard the OE dust boot because it is incompatible with these shocks. Do not reuse the OE rod collar. Fully seat the circlip in its selected groove and seat the spring-seat groove over it. Preserve the original lower-bushing orientation relative to the upper mounting studs.
Installation and safety
Installation must be performed by a professional suspension technician using the complete instructions. Do not use impact tools on the shaft nut. Check wheel alignment, brake/ABS operation, headlight aim and applicable driver-assistance calibrations after installation. Evaluate any other aftermarket suspension modifications for interference rather than assuming compatibility.
