These new reversible axle blocks improve chain adjustability from gearing changes and wear (chain stretch).
Each block has two positions depending on which way they are placed in the swingarm (12.5 or 3.5mm longer than stock).
Precision machined to reduce rocking for a more accurate chain alignment.
Each block is wider than stock to easily align the precision laser lines with the swingarm marks. Anodized YZ blue.
