Our innovative Billet Aluminum Chain Adjuster Blocks hold your wheel precisely in place while you tighten your chain. Our unique design features an integrated bolt slot so your blocks stay in position even when the axel is removed. Now making your chain adjustments requires only one 12mm wrench!
Each anodized 6061 aluminum block has permanently laser etched aligning marks. Our aligning marks are placed so that only one mark engages at a time making aligning a snap!
Fasteners have anti-sieze compound pre-applied to the threads. Includes installation instructions and two free Bolt stickers.
