First, even with the best geometry, a truck with crappy bushings won't turn very smoothly (that's not to say that good bushings will fix a bad truck either). Bushings are made of urethane. High quality urethane has a high rebound, which makes your trucks recover quickly after a turn or after landing a trick. But high quality urethane isn't cheap, so some truck companies try to save a few bucks by using low quality urethane to make bushings. These bushings are stiff and don't have much rebound. The result is a truck that feels slow and unresponsive. We use the highest quality American-made urethane bushings in all our trucks to give the best ride possible.
