Product Description
This genuine Yamaha factory-original right-hand (R/H) chain adjuster block slide fits into the rear swingarm end. Precision-machined from lightweight, high-strength aluminum alloy, it acts as the alignment collar for the rear wheel spindle bolt. It moves back and forth along the swingarm guide when adjusting the alignment bolt, keeping the rear wheel track straight and maintaining the correct drive chain tension.

Fitment Details
This is a brand-new, direct replacement. To install, loosen the main axle nut and slide out the axle shaft. Remove the old, pitted, or scratched adjuster block from the swingarm end. Slide this fresh OEM block into place, slide the axle back through, and adjust chain slack evenly on both sides using the rear adjusting bolts. Always use a torque wrench to tighten the rear axle nut to factory-specified limits to avoid crushing the block alignment tabs.
