What Is and Is NOT Included

Critical Compatibility

Knuckle type is a hard fitment split on the 2019–2023 Ranger 4WD platform. BDS engineers separate kits for cast aluminum and cast steel knuckles — the components are not interchangeable. Ordering the wrong knuckle kit results in fitment incompatibility and is a non-returnable error. Contact OFAS at (469) 407-7538 before ordering if you cannot confirm your knuckle type.

2019–2023 Ford Ranger 4WD Knuckle Kit Reference

Both kits deliver the same 3.5 inches of front lift with FOX 2.0 Performance Series coil-overs on the 2019–2023 Ranger 4WD platform. The knuckle type is the only variable — and it is determined by your specific truck's factory configuration, not a preference. Contact OFAS at (469) 407-7538 to confirm your knuckle type before ordering.

How to Confirm Your Knuckle Type

The 2019–2023 Ford Ranger 4WD was produced with both cast aluminum and cast steel front knuckles across the model run — the split is not cleanly divided by year or trim level. Do not assume based on year alone. Have a shop visually inspect the front knuckles before ordering, or contact OFAS at (469) 407-7538 and we will help you confirm the correct SKU before your order ships.

Installation Notes

Skill Level: Advanced. FOX 2.0 coil-over and knuckle installation on the Ranger 4WD platform requires a qualified suspension shop. This is not a bolt-on leveling spacer — the coil-over replaces both the factory strut and coil spring as an integrated unit, and the knuckles require proper installation torque and geometry setup. Do not attempt DIY installation.

Required Tools:

• Full hydraulic lift rated for Ranger weight
• Coil-over compression tool
• Torque wrench
• Full socket and wrench set
• Alignment equipment or alignment shop scheduled before driving post-install

Alignment: Full front-end alignment is mandatory after installation. Do not operate the vehicle on public roads before alignment is completed.

Knuckle Confirmation: Confirm cast aluminum knuckle configuration before the kit ships. Incorrect knuckle kit installed voids fitment compatibility — this is a non-returnable error. If you have any doubt, contact OFAS at (469) 407-7538 before ordering.

Break-In Period: Allow FOX 2.0 coil-overs to complete the FOX-recommended break-in period before aggressive off-road use. New coil-overs require a seating period before reaching optimal damping performance.

Extended Brake Lines: Verify whether extended brake lines are required for your specific configuration at time of installation.

Torque Specs: Follow BDS-specified torque values included in the installation instructions. Do not substitute generic torque values.

The Obsidian Take

SKU 1545FSL is the correct kit for the 2019–2023 Ford Ranger 4WD owner with confirmed cast aluminum knuckles who wants 3.5 inches of front lift with a genuine coil-over upgrade over the factory strut setup. The FOX 2.0 Performance Series coil-over replaces both the factory strut and the factory coil spring as a single integrated unit — this is not a strut spacer or a leveling kit. At 3.5 inches of lift, the Ranger sits aggressive, gains meaningful additional tire clearance, and rides on a damping system calibrated for the lifted geometry rather than fighting against it.

Cast aluminum knuckles are not the lesser option — they are the correct option for your truck's factory configuration. BDS engineers a knuckle specifically for each material type because the mounting geometry, load characteristics, and interface requirements differ between cast aluminum and cast steel. The knuckles included in 1545FSL are engineered to work with the FOX 2.0 coil-over at 3.5-inch lift height on the cast aluminum platform — not adapted from another application.

The comparison between 1545FSL and 1906FSL is knuckle material only. Same lift height, same FOX 2.0 Performance Series coil-overs, same platform. Your factory knuckle configuration is the only variable that determines which SKU applies to your truck — and it must be confirmed before ordering.

This kit is for you if: You own a 2019–2023 Ford Ranger 4WD with confirmed cast aluminum knuckles and want 3.5 inches of front lift with a complete FOX 2.0 coil-over system — not a spacer lift, not a strut extension, a purpose-built coil-over and knuckle system for your specific platform configuration.

This kit is not for you if: Your Ranger has cast steel knuckles — order SKU 1906FSL. Your Ranger is RWD or 2WD — this kit does not apply. You have a 2024 or newer Ranger — different platform entirely. You have a 2018 or earlier Ranger — the US-market Ranger was not sold from 2012 through 2018. Do not guess on knuckle type — confirm before ordering. The kit is non-returnable once installed.

Common Questions

How do I know if my Ranger has cast aluminum or cast steel knuckles?
The 2019–2023 Ranger 4WD was produced with both knuckle types across the model run — the split is not cleanly year or trim based. Have a shop visually inspect the front knuckles before ordering, or contact OFAS at (469) 407-7538. Do not estimate — ordering the wrong knuckle kit is a non-returnable error.

What is the difference between SKU 1545FSL and SKU 1906FSL?
Knuckle type only. Both kits deliver 3.5 inches of front lift with FOX 2.0 Performance Series coil-overs on the 2019–2023 Ranger 4WD platform. SKU 1545FSL includes cast aluminum knuckles and SKU 1906FSL includes cast steel knuckles. The kits are not interchangeable — your truck's factory knuckle configuration determines which SKU applies.

Does this kit replace the factory strut entirely?
Yes. The FOX 2.0 Performance Series coil-over replaces both the factory strut and the factory coil spring as a single integrated unit. This is not a strut spacer or leveling kit — it is a complete strut assembly replacement with FOX 2.0 damping calibrated for the lifted geometry.

Does this fit the 2024 Ford Ranger?
No. The 2024 Ranger is a different platform generation — this kit does not apply. Contact OFAS at (469) 407-7538 and we will identify the correct kit for your model year.

Was the Ranger sold in the US before 2019?
The US-market Ranger was discontinued after 2011 and not sold again until the 2019 model year. There is no US-market Ranger for 2012 through 2018. If you have a pre-2019 Ranger, it is a different generation entirely — contact OFAS to confirm the correct kit for your platform.

Does this kit include rear lift?
No. SKU 1545FSL is a front lift system only. Rear lift components are not included.

What size tires fit at 3.5-inch lift on the Ranger 4WD platform?
Confirm maximum tire diameter and wheel specifications with your wheel and tire supplier based on your specific cab and configuration before purchasing tires. OFAS does not certify specific tire sizes for this application.

What warranty covers this kit?
BDS suspension components are covered by the BDS No-Fine-Print Warranty. FOX 2.0 Performance Series coil-overs carry a FOX 1-year limited warranty.
