Durable knuckle with decent fit. Generates a little more wheel slop then the kyosho stock knuckle. This problem can be solved by using bearings that are 2.5 mm wide instead of the original 2 mm wide. If you are already suffering from a warped/tweaked chassis or uneven steering otherwise you might want to go for a more precise (expensive) knuckle. But if you often break knuckles this could be for you and the price is right.
