Made from high quality aluminum 6061T6 with POM collars to minimize tolerance, hence the bearing is able to tight fit into the knuckle arms for accurate turning. Easy to plug and play with high accuracy. POM is a good fit to protect the bearing from falling off due to friction. Multiple holes for installing the tie rods with these knuckle arms.
