Details
Upgrade your 2021–2026 Ford Bronco with a WePro premium spline-drive lug nut kit for compatible aftermarket wheels. Each kit includes 24 closed-end lug nuts and one spline key.
Ford Bronco Fitment
These kits use the correct M12x1.5 thread for the standard 2021–2026 Ford Bronco, with a conical seat for compatible aftermarket wheels. They are intended for 6-lug wheel applications that use conical-seat spline lug nuts.

- 1 spline key
WePro Quality & Warranty
WePro manufactures these lug kits in Taiwan and backs them with a 2-year finish warranty and a 7-year structural warranty, subject to WePro's warranty terms.
Installation Notes
Confirm that your wheel uses a conical lug seat before installation. Start each lug nut by hand and torque the wheels to Ford's specified torque using a calibrated torque wrench. Recheck wheel torque after installation according to the wheel manufacturer's recommendations.
Note: These M12x1.5 kits are for the standard full-size Bronco. Bronco Raptor uses different wheel-stud hardware and should not use these kits unless fitment is independently confirmed.

Questions
Do these lug nuts fit the factory Ford Bronco wheels?
The thread size matches every 2021 through 2026 Bronco. The wheel must have a conical lug seat and lug holes that fit a spline drive nut. They are made for aftermarket wheels like the THRET Offroad line.
How many lug nuts come in one kit?
Each kit has 24 lug nuts. That covers four wheels with six lugs each.
Is a spline key included?
Yes. Each kit comes with a spline key that has a hex end for a 3/4-inch or 13/16-inch socket.
Should I pick the Standard or Long length?
Pick Long if your wheel has a thick mounting pad. The lug nut should turn at least 14 full turns onto the 14mm stud before it is snug.
What is the difference between Black and Chrome?
Only the finish. Both are closed-end spline drive lug nuts with the same thread, seat, and lengths.
