Bolt Motorcycle Hardware Adjustable Axle Blocks for Yamaha WR-F, YZ-X, YZ and YZ-F models with 20mm Axle

Stop struggling with misaligned wheels and multiple wrenches. The BOLT Chain Adjuster Blocks are a high-performance upgrade for your Yamaha, designed to hold the rear wheel precisely in place while tightening your chain. Unlike the stock hardware, these billet aluminum blocks stay in position even when the axle is removed, making track-side wheel swaps significantly faster.

The unique design allows you to perform a full chain adjustment using only a single 10mm wrench, eliminating the need for bulky tools and constant double-checking of your alignment marks.

Features:

• Single-Wrench Adjustments: The innovative integrated bolt slot means you only need one 10mm wrench to dial in your chain tension.

• Precise Alignment: Features permanently aligning marks ensure perfect alignment

• 6061 Billet Aluminum: CNC-machined 6061 aluminum for maximum durability and a clean look.

• Axle Retention: These blocks are designed to stay in the swingarm during wheel removal, preventing the headache of searching for dropped hardware in the dirt.

• Ready to Install: Each kit includes high-tensile fasteners with a 1 gram pack ofanti-seize compoundfor application to prevent galling the threads.

• Made in the USA
