Eibach PRO-TRUCK-LIFT Stage 1 Spring & Shock Kit
E80-35-056-03-22 combines four matched lift springs with four PRO-TRUCK sport shocks for balanced road control and trail capability. Height-adjustable clips provide spring-seat settings for the intended application. This is a spring-and-shock system requiring assembly, not the threaded Coilover 2.0 kit or a preassembled coilover package.
Current manufacturer applications
Eibach's exact-part catalog lists 2021–2026 Ford Bronco, two-door/four-door, 2.3L or 2.7L EcoBoost, 4WD, with:
- HOSS 1.0 and base black shocks.
- HOSS 2.0 with Sasquatch package.
- HOSS 3.0 with Fox internal-bypass non-live-valve shocks.
Verify the vehicle's actual factory suspension against a listed application. This is not blanket coverage for every trim; do not assume Raptor/live-valve systems, Bronco Sport or unlisted configurations fit. Replacing the original shocks does not retain their original damping technology.
Included components and lift
- Two front springs, F31-35-056-03-FA, with two front shocks, 35166.8003: the D4052 OE-Hitachi baseline chart lists front heights of 1.3, 2.3 and 3.3 inches for 2.3L engines, or 0.8, 1.75 and 2.8 inches for 2.7L engines. Higher settings marked for extra weight must only be used with extra weight.
- Two rear springs, F31-35-056-03-RA, with two rear shocks, 35166.8004: the same OE-Hitachi baseline chart lists rear heights of 0.6, 1.5 and 2.4 inches. Higher settings marked for extra weight must only be used with extra weight.
- Two front hardware kits, 35148.8000HK.
These exact component quantities are from D4052. Factory springs are not compatible with the Eibach shocks. Use the matched springs supplied for this system.
Understanding the lift chart
The linked D4052 sheet explicitly bases its height figures on Broncos originally equipped with OE Hitachi shocks. Do not apply those numerical lift figures directly to Sasquatch/HOSS 2.0 or HOSS 3.0 vehicles simply because the current product page lists those applications. Confirm the appropriate package-specific setup and expected lift with Eibach.
The figures above are chart values, not numbered groove assignments or guaranteed height on every vehicle. Follow the illustrated spring-seat settings and extra-weight restrictions; no unsupported groove mapping is supplied here. Eibach notes that two-door models will see slightly increased lift, without providing a numerical correction in the retrieved sheet.
Assembly and OE parts
D4052 calls for OE spring-perch transfer to the Eibach damper and transfer of the illustrated OE stem spacer on both front and rear shocks. Use supplied new hardware where provided and retain serviceable OE hardware elsewhere as directed. Confirm the correct OE-part transfer procedure for the vehicle's specific factory damper package before disassembly.
Fully seat the snap ring in its groove and install the spacer perch in the illustrated orientation, ensuring the ring engages the groove beneath the perch. Improper seating can permanently damage the shock.
Installation checks
Use a qualified suspension installer and the complete Eibach instructions together with the vehicle service manual. Properly support the vehicle, inspect mounting points, and check brake/fuel lines, wiring and exhaust clearance before driving. D4052 directs a cautious initial road test and inspection after 10 miles, including fastener torque and component-clearance checks. Set alignment and verify actual wheel/tire clearance after installation.
