Eibach PRO-TRUCK Coilover 2.0 Front & Rear Kit
E86-35-056-01-22 is a Stage 2 system with assembled PRO-TRUCK Coilover 2.0 units at all four corners. Threaded bodies allow ride-height fine-tuning, while 46mm pistons, a nitrogen-filled monotube design and variable-force valving provide damping control for the road and trail. Eibach specifies anodized 6061-T6 billet aluminum coilover mounts and ERO off-road race springs, with individual dyno testing for matched performance.
Verified applications
Eibach's current exact-part catalog lists 2021–2026 Ford Bronco, two-door and four-door, 2.3L or 2.7L EcoBoost, 4WD in these configurations:
- HOSS 1.0 with base black shocks.
- HOSS 2.0 with Sasquatch package.
- HOSS 3.0 with Fox internal-bypass non-live-valve shocks.
- Badlands without Sasquatch.
Match the actual factory suspension to one of those applications. This is not a blanket fitment claim for Raptor, live-valve systems, Bronco Sport or unlisted configurations. Replacing factory dampers is not a promise to retain their original damping technology.
Included components and lift
- Two front coilover assemblies, 35166.9003: package- and engine-specific front lift; see the documented chart below.
- Two rear coilover assemblies, 35166.9004: package-specific rear lift; see the documented chart below.
- Two hardware kits, 35148.8000HK.
- One 2.0 coil spanner wrench, ETC2.0.
These quantities come from the exact kit's D3991 Rev 4 instructions. This is the standard kit, not the separate HD version.
Documented typical lift heights
The following figures are in inches from D3991 Rev 4. Each entry gives out-of-box front/rear lift, followed by front adjustment range and rear adjustment range. They are chart values, not guaranteed measured heights on every vehicle.
- 2.7L Base, Big Bend, Black Diamond or Outer Banks: 3.0 / 3.1 out of box; front 1.0–3.3; rear 2.4–3.8.
- 2.7L Badlands: 2.3 / 2.4 out of box; front 0.3–2.6; rear 1.7–3.1.
- 2.7L Sasquatch, Wildtrak or First Edition: 1.9 / 2.0 out of box; front 0.0–2.2; rear 1.3–2.7.
- 2.3L Base, Big Bend, Black Diamond or Outer Banks: 3.6 / 3.0 out of box; front 1.5–4.1; rear 2.4–3.8.
- 2.3L Badlands: 2.9 / 2.3 out of box; front 0.8–3.4; rear 1.7–3.1.
- 2.3L Sasquatch: 2.5 / 1.9 out of box; front 0.4–3.0; rear 1.3–2.7.
The shared chart does not separately quantify every current HOSS 3.0 application; do not infer that an older trim-based row establishes its exact lift. Confirm the applicable setup with Eibach. Exact heights vary with package, accessories and weight distribution, and Eibach notes two-door models will see slightly increased lift. The chart does not provide a separate numeric two-door correction.
Threaded adjustment limits
Front maximum collar height: 84mm. Rear maximum collar height: 148mm. Both are measured from the bottom of the spring collar to the base exactly as illustrated on page 10. These are collar dimensions, not vehicle lift heights; do not exceed them.
The instructions estimate that approximately 11/16 inch of front collar movement produces 1 inch of front ride-height change, while approximately 1 inch of rear collar movement produces 1 inch of rear ride-height change. Set both sides of an axle equally and follow the full adjustment procedure.
Installation notes
Professional installation is required. Eibach specifically warns that the front axle must be removed from the hub during front shock removal to prevent axle-assembly damage from overextension. Properly support the knuckle and rear axle during the work and follow all illustrated removal, mounting and reassembly steps.
Do not use impact tools on shock piston components, shafts or rod nuts. After installation, inspect wheel alignment, wheel/tire-to-fender clearance, brake-line routing and attachment, and ABS sensors. Installation instructions and vehicle-specific torque requirements control the work; this listing is not a substitute.
Warranty and identification
Eibach lists a two-year warranty, subject to its terms, exclusions and application requirements. SKU and manufacturer part number: E86-35-056-01-22. Barcode: 803050515582.
