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). They are precision machined to reduce rocking for more accurate chain alignment. Each block is wider than stock to easily align the precision laser lines with the swingarm marks. Getting the rear wheel square is a snap even for rider’s that wear glasses. MSRP is $54.95 per set and available in red or blue. In stock now for the following models:

2010-2020 YZ450F & 2012-2020 YZ250F; 2002-2020 YZ125/125X/250/250X; 2002-2020 WR250F/450F; 2015-2020 YZ250FX/45FX; 2002-2008 YZ250F/426F/450F
