Eibach R40006 ERL OEM Front Coil Springs 2019-2023 Ford Ranger 2.3L EcoBoost 4WD

Vehicle Fitment

• 2019-2023 Ford Ranger (2.3L EcoBoost, 4WD) - All trims (XL, XLT, Lariat, FX4)

Fitment Notes

• 4WD configurations only - the 2WD Ranger uses a different front spring and requires a separate Eibach ERL part number (R40005).
• Sold as a single spring. Two are required for a complete front spring replacement - order quantity 2 for a full axle service.
• This is an OEM-equivalent replacement spring intended to restore stock ride height and handling characteristics. It does not raise or lower the vehicle. If a lift is desired, see Eibach's PRO-LIFT-KIT (E30-35-048-01-20) or PRO-TRUCK-LIFT Stage 1 (E80-35-048-01-22) for the 2019-2023 Ranger 4WD.
• Ride height after installation may vary slightly based on the condition and wear state of other suspension components - worn bushings, ball joints, or shock absorbers can affect final ride height regardless of spring condition.
• Fits the 2nd-generation Ford Ranger (P703 platform) sold in North America from 2019 through 2023. Does not fit the 2024+ Ranger (3rd-generation), which uses a different platform and spring geometry.

Features

• OE-equivalent replacement: manufactured to OE design specifications and IATF 16949 quality guidelines - the same international automotive quality management standard used by original equipment manufacturers
• Zinc phosphating applied as a pre-treatment before powder coating, providing a corrosion-inhibiting base layer that prevents rust infiltration at the spring wire surface - a step beyond standard single-coat finishes
• Subjected to both static and dynamic durability testing before release - validated to withstand the full range of loads experienced during normal truck use including towing, hauling, and off-road driving
• Developed in partnership with OEM suppliers and car manufacturers, reflecting Eibach's extensive history as a Tier 1 spring supplier to global automotive brands
• Restores factory spring rate and ride height without any suspension geometry changes - a direct, confirmed-fit replacement
• Progressive spring design provides a compliant initial rate for light loads with a firmer response as compression increases, matching the original spring's behavior across the full load range
• Developed and produced in the USA and Germany - Eibach facilities in Corona, California and Finnentrop, Germany

Product Description

The Eibach R40006 is a Factory Replacement Line (ERL) front coil spring for the 2019-2023 Ford Ranger in 4WD configuration. The ERL program is Eibach's OEM-grade replacement spring line, built to the same IATF 16949 quality standard used by original equipment manufacturers worldwide. Unlike generic aftermarket replacement springs, which are often manufactured to broad tolerances to fit multiple applications, the R40006 is engineered specifically for the P703-platform Ranger's front suspension geometry and load requirements, with the spring rate, free length, and end configuration matched exactly to Ford's OEM specification. The result is a replacement that restores factory ride height, spring rate, and handling behavior without any deviation from the vehicle's original suspension setup.

Eibach's ERL springs go beyond bare-metal coating with a zinc phosphating pre-treatment applied before the final powder coat finish. Zinc phosphate forms a conversion layer on the wire surface that chemically bonds to the metal and inhibits corrosion at the molecular level - preventing the rust infiltration that can cause traditional coatings to bubble and peel over time. This two-stage corrosion protection is especially relevant for a front coil spring on a truck that may see salt, mud, and moisture exposure throughout its service life. Each spring also undergoes static and dynamic durability testing before release, simulating the full range of real-world load cycles the spring will experience in service.

This spring is sold as a single unit - two are required to replace both front coil springs. It is a direct stock-height replacement and does not alter ride height or handling characteristics beyond restoring OEM specification. 4WD Ranger owners looking to lift their truck rather than simply replace worn springs should reference Eibach's PRO-LIFT-KIT or PRO-TRUCK-LIFT Stage 1 systems for the 2019-2023 Ranger 4WD. This part number covers 4WD models only; the corresponding 2WD front replacement spring is Eibach R40005. This part does not fit the 2024 and newer Ranger, which uses a different front suspension design.
