Although  Chevy and Ford trucks also fit 14x1.5 lugs, the closed end design is a little too short. We recommend open end lug nuts for Chevy and Ford trucks instead (available on Amazon, Ebay or at offroad installation shops). Why use ET (extended thread): It's a known issue that Toyota trucks have short wheel studs. Upgrading to aftermarket wheels causes the lug seating to change to a conical seating, which then results in less thread engagement than what the factory wheels and lug nuts can obtain.  The solution is to use our compatible ET (extended thread) lug nuts. The shank of the lug nuts fit snugly into the wheel's lughole, resulting in more thread engagement and a better peace of mind.  Another benefit is the wheels are now not only hub-centric, but also lug centric. Using ET lug nuts provides the same amount of wheel securement that a factory OEM wheel/lug nut setup would supply.  Our ET lug nuts are compatible with all of our wheels.
