What size are the lug nuts on a Ford Ranger?
The lug nut size on a Ford Ranger is not fixed across all years. In practice, late-model Rangers use M12 x 1.75 lug nuts, while older Rangers with 9/16"-18 wheel studs typically use 9/16"-18 lug nuts. Always verify for your exact year and wheel package.
Generational differences
Newer Rangers (2019–present)
Rangers in this generation commonly use six-lug wheels that attach to M12 x 1.75 studs. The OEM lug nuts are typically sized to match that thread, and the standard socket size is often around 21 mm, though aftermarket wheels may differ. Confirm with your vehicle’s documentation or the nut itself.
Earlier Rangers (1993–2011)
Rangers from earlier generations also use six-lug wheels but with 9/16"-18 wheel studs. Lug nuts for this setup are typically 9/16"-18 with a hex size around 21 mm (roughly 13/16 inch) for many designs; again, verify based on your exact year and wheel configuration, especially if aftermarket wheels are present.
How to confirm the exact lug nut size for your Ranger
To confirm the lug nut size for your Ford Ranger, use these steps:
- Check the owner’s manual or Ford’s official service documentation for the lug nut specification for your exact year and trim.
- Inspect the lug nuts themselves; if you can read any numbers or markings on the nut, they can indicate the correct size (for example, the hex size stamped on the nut or the part number).
- Measure the stud diameter with calipers: a 12 mm stud typically corresponds to M12 x 1.75 nuts; a 9/16" stud corresponds to 0.625 inches (approximately 15.9 mm).
- If you’re unsure, remove one lug nut and take it to a parts counter with your vehicle details to get the correct replacement.
Following these steps will help ensure you use the right lug nut size, avoiding improper torque and potential wheel loss.
Summary
Ford Ranger lug nut sizes vary by generation and wheel choice. Newer Rangers typically use M12 x 1.75 lug nuts, while older models commonly use 9/16"-18 nuts. Always verify using the official manuals or the nut markings, and follow the manufacturer’s torque specifications when installing wheels.
