Billet Aluminum Chain Adjuster Blocks - Designed to hold the wheel precisely in place while you tighten the chain and stay in position even when the axle is removed! Bolt's unique design means only
one 10mm wrench is needed to make your chain adjustments. One block is threaded for your existing stock axle. Each anodized 6061 aluminum block has laser etched aligning marks and has lubricant pre-applied to threads on custom stainless
steel fastener. Each anodized 6061 aluminum block has permanently laser etched aligning marks. The aligning marks are placed so that only one mark engages at a time making aligning a snap!
This kit includes a specially designed Square Nut for stock axle block removal. Bolt hardware meets or exceeds OEM specs. Proudly made in the USA.
