Using these AS3 rear axle blocks is simple. First, make sure your Kawasaki bike is on a stable surface. Then, remove the old axle blocks carefully. Place the new AS3 blocks in the swing arm and around the rear wheel spindle. Use the alignment scales on the blocks to position the rear wheel accurately. When installing, ensure that everything fits snugly but don't overtighten the bolts. As for maintenance, keep the blocks clean. You can wipe them down with a soft cloth after each ride. If they get dirty, use a mild soap and water solution. Don't use abrasive cleaners as they may damage the anodised finish. If you notice any signs of wear or damage, contact us as the blocks come with a 12 - month warranty.
