Regular tapered seat lug nuts do work with American Racing Torq-Thrust and Legendary wheels, but due to the added thickness of the aluminum, as compared to original steel wheels, the contact area between the lug nut and threaded stud is reduced. For extra security, or if your ride is making some serious power, this type of lug nut gives you the best of both worlds. They have the 60 degree tapered seat to keep your wheel centered, and a 0.33" long/0.61" wide shank which increases the contact surfaces dramatically. Each one is cold-forged steel for strength, and chrome plated for beauty. You also get four valve stems with chrome caps and decorative sleeves. Even if you don't need them for this installation they are a standard size, so you can use them for another vehicle.
NOTE: Some older 2-Piece Torq-Thrust wheels have slightly smaller lug nut holes. To use these lug nuts a 5/8" drill bit will need to be run through them. A drill-press is recommended.
If you're planning on putting new aluminum wheels under an older vehicle, especially from the early 70's or older, wheel stud length can be an issue. These older cars usually have shorter wheel studs because they only came with thin steel wheels.For safety, the thread engagement of a wheel stud into the lug nut must be equal to at least the diameter of the stud. So, a 7/16-20 stud would need 7/16 in. engagement, or about 9 full turns of the lug nut; a 1/2-20 stud would need 1/2 in. engagement, or 10 full turns of a lug nut.If your wheel studs are too short, longer studs are always a solution. But, an easier option for wheels with conical seats would be to use ET Style lug nuts. These lug nuts have the same 60Ã‚Â° conical seat plus a small 0.300" long shank that will fit into most aftermarket wheels. This equates to about 6 additional full turns of thread engagement, which will usually allow for safe installation of the wheels.
