Wheel Adapters (4)

These off road / circle track application wide 5 wheel adapters are 3/8" steel with 5/8" UNF studs. Adapts your "early modified" wheels to todays more popular bolt patterns.  Not recommended for street /over the highway use.

Must use spacer with drum brake. The bolt heads on the back side of the adapter do not sit flush, contacting the brake drum. The thickness of the spacer would depend on the specific brake drum being used, but the 1/4" 916-58210 or 3/8" 916-58212 should work for many applications. Both of these spacers would work on the 916-58251.

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

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

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 of our lug nuts are 45° and designed to be used with racing wheels.
