Details

Use these oversized 1 Inch Hex Steel lug nuts in plane of those 'puny' stock size lug nuts.

You will need a 1" hex (6-sided) socket. 

1/2" Fine Thread fits most Ford and Mopar pattern studs.

  • 45° taper
  • 1/2" RH Fine Thread, Single Taper
  • Set of 20

What's The Angle
Most racing wheels have a 45° seat for the lug nut to seat in while most street wheels use 60°. By using 45° the lug nut is able to clamp tighter over a larger area, which helps keep your wheels on the car where they belong.

If you mix and match street and race wheels or lug nuts you are just asking for trouble. All our lug nuts are 45° and designed to be used with racing wheels.
