Bolt's innovative Billet Aluminum Chain Adjuster Blocks hold your wheel precisely in place while you tighten your chain. The unique design features an integrated bolt slot so your blocks stay in position even when the axle is removed. Now chain adjustments require only one 10mm wrench! Each anodized 6061 aluminum block has bright laser etched alignment marks. These permanent and easy to see marks make wheel alignment a snap! Fasteners have anti-seize compound pre-applied to the threads.
