ReadyLIFT® 10-3485 - Billet Aluminum Wheel Spacers

Raising your GM 2007-up Silverado or Sierra pickup or GM SUV a full 4" will help find room for much larger tires, which is terrific for off-roading. The world isn't all dirt, however, and sometimes it helps to be able to bolt the stock wheels and tires back on and use your truck on the pavement. Unfortunately, the stock rubber will contact the suspension, because the stock wheel doesn't have enough negative offset.

These CNC-Machined wheel spacers don't simply sandwich between the wheel and hub. They bolt to the hub with the original lug nuts, and have their own studs and lug nuts. Otherwise, the lug nuts won't have full engagement with the threads on the hub's studs (6 full turns of engagement is required). These spacers have OEM-grade studs already pressed into place, and come with lug nuts to fit.

Be aware that these spacers are designed to be used with the original-equipment wheel that have pockets cast into the back face of the wheel between the lugs. They will not work with the standard steel wheels or aftermarket wheels that have a flat mounting face. The original stud protrudes too far and will foul the wheel.

Your original wheels are hubcentric: the wheel has a center bore that fits exactly on a lip on a hub to make sure the wheel is exactly centered. These spacers are hubcentric to the hub, and the spacer has a lip on it in turn to center the wheel, ensuring that your wheels will run true. When using these spacers, the wheels will line up with the lip of the fender, not stick out past it. You could use these spacers to tweak the offset on any vehicle that uses the 6-5.5" bolt circle and the correct 78 mm center-hub diameter.
