Especially developed for model cars 1:5 with M8 thread for 5 mm screws. Available with left and right thread. Using alloy for the outside body means less weight in comparison to normal steel ball ends in trade. The alloy coating provides the necessary strength. Extraordinary is the smooth movement of the ball in the middle of the maintenance free body. These ball ends can be used everywhere normal plastic ball ends with M8 thread are used. The main advantage is the clearance free an stable connection between the a-arms rear lower and the chassis or between the a-arm front and the axle shaft.
