WHEEL SPACERS: Dinan's Wheel Spacers physically move the wheel further away from the hub. In doing so, they give your wheels the desired offset needed to create the stance or look you desire, or clearance necessary to clear brake calipers. When using wheel spacers, longer bolts are required. These are are sold separately but appropriate length bolts for the selected spacer kit are called out below in the "We Suggest" section. Please ensure to pair the correct thread size bolts for your specific application using the general application guide located on the bottom of the product page. LUG BOLTS: Longer lug bolts for use with wheel spacers. Please ensure to pair the correct thread size bolts for your specific application/spacer using the general application guide located on the bottom of the product page.
