Eibach PRO-LIFT Four-Spring Kit
E30-35-056-01-22 replaces the front and rear coil springs on compatible Ford Broncos while retaining the specified factory dampers. This is a set of four springs only, not replacement shocks, a spacer lift or preassembled coilovers. Eibach designs the springs for increased ground and fender clearance with on-road stability and off-road capability.
Current manufacturer applications
Eibach's exact-part page lists 2021–2026 Ford Bronco, two-door/four-door, 2.3L or 2.7L EcoBoost, 4WD, in these configurations:
- HOSS 2.0 with Sasquatch package: factory Bilstein PSD dampers.
- HOSS 3.0: factory Fox internal-bypass non-live-valve dampers.
For use with those HOSS 2.0 Bilstein PSD or HOSS 3.0 Fox dampers only. Do not assume compatibility with base HOSS 1.0 black shocks, Raptor/live-valve systems, Bronco Sport, aftermarket Bilstein 6112 shocks or any unlisted suspension configuration.
Included components and lift
- Two front springs, F31-35-056-01-FA: front lift-producing springs for the specified factory damper applications.
- Two rear springs, F31-35-056-01-RA: rear lift-producing springs for the specified factory damper applications.
- No shock absorbers or assembled coilovers included.
The retrieved exact-part page and D4020 instructions do not establish a numerical front/rear lift table, so no universal lift height is promised here. Eibach notes that actual lift depends on package and weight distribution, with slightly increased lift on two-door models. Confirm the expected height for the exact vehicle with Eibach rather than using a different kit's figures.
Important documentation distinction
The current product page explicitly includes HOSS 3.0 Fox non-live-valve applications. The linked D4020 instruction sheet, created in 2022, still describes Sasquatch-package PSD shocks only. Its older application wording does not independently document the newer Fox installation. For HOSS 3.0, obtain the appropriate current installation guidance from Eibach before starting.
OE parts and installation
D4020 identifies reuse of the original spring isolators and dampers, plus the OE front and rear bump stops. No bump-stop trimming is specified in that sheet. Inspect reused parts for condition and follow the applicable complete instructions for the confirmed suspension.
Installation should be performed by a qualified suspension mechanic using proper vehicle support and spring-handling equipment. Install the Eibach logos right-side-up. Do not use impact tools on shock piston components, shafts or piston-rod nuts. Preserve the required upper/lower perch orientation during disassembly and reassembly.
After installation, inspect and adjust alignment, aftermarket wheel/tire-to-fender clearance, brake-line routing and attachments, and ABS sensors. The spring kit does not guarantee clearance for a particular tire size.
Warranty and identification
Eibach lists a five-year warranty, subject to its terms, exclusions and application requirements. SKU and manufacturer part number: E30-35-056-01-22. Barcode: 803050523105. Made in the USA.
