What Is and Is NOT Included

Critical Compatibility

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

Text (469) 407-7538 to confirm your knuckle type and shock tier preference 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 text (469) 407-7538 and we will help you confirm the correct SKU before your order ships.

Installation Notes

Skill Level: Intermediate to advanced. Front lift component and knuckle installation on the Ranger 4WD platform requires a qualified suspension shop. Proper lifting equipment, correct torque procedures, and alignment setup are required. Do not attempt DIY installation.

Required Tools:

• Full hydraulic lift rated for Ranger weight
• 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. Text (469) 407-7538 before ordering if you have any doubt.

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.

Tire Fitment: At 3.5 inches of front lift on the Ranger platform, typical fitment runs 33–35-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specifications with your wheel and tire supplier before ordering.

The Obsidian Take

SKU 1545FS is the mid-tier entry into the BDS Ranger 4WD cast aluminum knuckle lineup. FOX 2.0 Performance Series shocks deliver a genuine damping upgrade over both the factory shock and the NX2 Nitro entry tier — better heat resistance, improved valving, and a more refined ride quality at 3.5 inches of lift. This is the correct kit for the Ranger owner who wants FOX-branded damping performance without stepping up to the full coil-over system in SKU 1545FSL.

The decision between 1545FS and 1545H is straightforward — if you trail ride with any regularity, run this Ranger on rough surfaces consistently, or simply want a shock that holds up better under sustained use than the NX2 Nitro, 1545FS is the correct choice. The FOX 2.0 Performance Series is a proven shock that outperforms entry-level alternatives in heat management and damping consistency over time. For a daily driver with minimal off-road exposure, the NX2 Nitro in 1545H handles the job at a lower price point. Once trail use enters the equation, 1545FS is the correct minimum tier.

The decision between 1545FS and 1545FSL is system type. SKU 1545FSL uses FOX 2.0 coil-overs — replacing both the factory strut and coil spring as a single integrated unit. The coil-over provides better geometry integration at lifted height and a more complete front suspension upgrade. If you want the most capable front suspension system available for the cast aluminum knuckle Ranger at 3.5 inches, 1545FSL is the correct choice. If standalone FOX 2.0 shock performance at a lower price point meets your use case, 1545FS is the correct call.

This kit is for you if: You own a 2019–2023 Ford Ranger 4WD with confirmed cast aluminum knuckles, you want 3.5 inches of front lift with FOX 2.0 Performance Series damping at the mid-tier price point, and a standalone shock — not a full coil-over system — fits your build and budget.

This kit is not for you if: Your Ranger has cast steel knuckles — order SKU 1906FSL. You want the entry-level price point — order SKU 1545H. You want a full coil-over system — order SKU 1545FSL. Your Ranger is 2WD — this kit does not apply. You have a 2024 or newer Ranger — text OFAS to confirm the correct kit. 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 text (469) 407-7538. Do not estimate — ordering the wrong knuckle kit is a non-returnable error.

What is the difference between SKU 1545FS, SKU 1545H, and SKU 1545FSL?
All three kits fit the 2019–2023 Ranger 4WD with cast aluminum knuckles and deliver 3.5 inches of front lift. The difference is the shock tier — 1545H uses NX2 Nitro entry-level shocks, 1545FS uses FOX 2.0 Performance Series standalone shocks, and 1545FSL uses FOX 2.0 Performance Series coil-overs that replace both the factory strut and spring as an integrated unit. If you want FOX damping without the full coil-over price, 1545FS is the correct choice. Text (469) 407-7538 to confirm which fits your use case.

What is the difference between SKU 1545FS and SKU 1906FSL?
Knuckle type and system type. SKU 1545FS is for cast aluminum knuckles with FOX 2.0 standalone shocks. SKU 1906FSL is for cast steel knuckles with FOX 2.0 coil-overs. These kits are not interchangeable on either variable — confirm your knuckle type before ordering.

Does this fit the 2024 Ford Ranger?
Not confirmed. Text (469) 407-7538 before ordering a 2024 model year — do not assume compatibility.

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

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