Mark Williams has a large variety of lug nuts in stock and ready to ship! Our lug nuts integrate the lug nut and washer into one complete assembly. The washer is free to rotate independently from the nut, helping prevent damage and marring to the wheel while also eliminating the hassle of loose washers. The self aligning washer design helps maintain an even load against the wheel and studs. Our steel lug nuts are manufactured from Class 3A steel, while our aluminum washers and aluminum lug nuts are machined from high-strength 7075 aluminum. Whether you’re building a race car, street car, or anything in between, Mark Williams lug nuts are designed to provide reliable clamping force while helping protect your wheels from damage. For your next project, upgrade to a set of Mark Williams lug nuts and eliminate the worry of marred wheels and lost washers!

Devin Vanderhoof and Matthew Smith wasted no time getting the new Mark Williams modular under Devins Mustang they call Rediwhip! This modular was built with an upper wishbone mount and our new Apex bracketry for fine 4 link and shock adjustment. We also set Devin up with two sets of spacers/ end bells and axles so that he can switch between 10.5 slick backspacing wheel/tire combo and radial tire combo length by unbolting and bolting the different spacer and sliding in new axles. This way he can easily adapt to whatever racing is happening!
