The axle covers themselves appear to be of decent quality although they are definitely lighter than the competition! The chrome finish appears to be good on both the axle caps and nut caps. THE PROBLEM is related to union nuts with 33M thread! They are of very poor quality! The plastic threads on about half of the wheel nut caps were not machined or tapped properly during manufacture, making the caps extremely difficult to thread onto the wheel studs! I bought two complete sets for two separate trailers and both sets were defective! Time will tell how long these last. I have doubts. Because they are MADE IN CHINA! Do yourself a favour, spend a little more money and get yourself a quality set! You get what you pay for! :-(
