I changed to these shocks about halfway through my 2012 season and have never looked back. They were such a huge improvement I regret not buying them sooner. The first night, they took a hard lick, getting tossed into the air about 10 feet and landing without even a hint of damage. They went through another 15 races without an issue and helped me win many races.
