Steel spacers are extremely heavy, and greatly, negatively impact your vehicle in many ways. From gas economy to wear and tear, when you are driving any vehicle on the road, you want the least amount of "Unsprung weight" Possible. You need braking power & you need it instantly. When you add "unsprung weight" to any vehicle it means that your suspension components have to work harder to keep the wheel on the ground, and it puts much unneeded stress on your axles, joints, control arms, transmission etc. plus much more. You can feel the stopping power greatly decrease when adding steel spacers to your vehicle as well as the over all ride quality greatly decrease. Our Solid Extruded American Made Billet Aluminum is almost 3 times lighter than steel spacers making it ideal in every manner to keep your vehicle, as close to OEM as possible. The strength of our Billet is overkill enough as it is, & our spacers will hold up against anything you throw at them. We have sold hundreds of thousands of spacers & adapters throughout the years & even though raw steel is upwards of 10x cheaper than billet, we have chosen not to skimp out on the quality and effectiveness billet aluminum has to offer! Check the link below for more information on unsprung weight / mass. Click Here For Unsprung Weight Detailed Information   Important installation information If the studs on the hub are longer than the thickness of the wheel adapters the studs will need to be trimmed so they do not protrude past the thickness of the adapter & so the wheel can sit flush on the adapter/spacer face. This set comes complete with a set of open end lug nuts stated above, please make sure your vehicles studs matches the thread pitch of the lugs provided or you may need to purchase a lug nut kit to accommodate proper installation. Lots of people install these at home, but we always strongly recommend professional installation. If you're not sure if these wheel adapters will work with your vehicle, send us a message or an email so we can get you set up, and ready to roll! Uses and facts about our spacers and adapters Our wheel spacers and adapters are commonly used for multiple reasons, from eliminating wheel & tire rubbing against shocks and struts, clearing break calipers, making room for larger tire clearance, or to adapt the bolt pattern of your vehicle in order to fit different wheels / rims. They will increase driving stability and handling performance by widening the track of your vehicle, and improve the look of your vehicle by giving you a more aggressive stance. All of our spacers and adapters come standard with heat-treated, hardened steel studs. Lastly we only use Aerospace grade 6061 T-6 Solid Billet Aluminum on all of our wheel spacers and adapters.
