Polyurethane bushings are great for upper control arms, shackles, and even motor mounts. These bushings not only have a longer effective lifespan, but they also hold up better under the stresses that spirited driving can inflict on the original suspension bushings. They provide good vibration dampening compared to the firmer bushings such as delrin. We recommend using Probearing grease with polyurethane bushings for superior lubrication and to help prevent squeaks.
