They are also compatible with most aftermarket wheels that use a 9/16-18 thread pitch and a 60-degree conical seat. It's essential to confirm the correct thread pitch and seat type for your specific vehicle and wheels to ensure a proper and safe fit.
Compatible vehicles
- Ford: 1988-1998 F250, F350
- Dodge: 1994-2010 Ram 2500, 3500; 2002-2010 Ram 1500; 2004-2009 Durango; 2005-2011 Dakota

Important considerations
- Aftermarket vs. OEM: Some lug nuts are designed for aftermarket wheels, while others are direct replacements for original equipment manufacturer (OEM) wheels. Make sure the lug nuts match the type of wheels you have.
- Thread pitch: The "9/16-18" specifies the size and thread count. The "9/16" refers to the stud diameter, and the "18" is the number of threads per inch. You must match this to your vehicle's studs.
- Seat type: The seat type (e.g., conical, spherical) must match your wheel to ensure proper contact and secure mounting.
- Confirm fitment: Always verify the exact fitment for your specific year, make, and model before purchasing.
