Upgrade caster wheels for Razor Crazy cart Max fit non-shattering Pair GREAY

These are upgrade crazy cart wheels that fit In the stock crazy cart casters, The are designed to be less shatter-able then the stock rear caster wheels. These wheels are not invincible, while they are way less likely to shatter they may soften at constant speeds around 30 miles an hour. To install Wheels: First remove stock crazy cart rear caster wheels, then remove the bearings from the stock wheels Then press in the bearings into the new wheels (This can be done with a standard vise or a hammer). Next depending on which crazy cat model you have and how worn your stock casters are you may need to cut the stock spacers in half, (this will not affect the performance of the crazy cart.) Finally put one spacer either side of the wheel and slide the stock axle through the middle, after this tighten everything together (WITH LOCKTITE) until the wheel can freely spin without too much resistance. Then repeat on the other side.
