These steering blocks and C hubs are well made. But when installing them you can’t use the original vorteks bushings because they are to short, and the c hub binds up if the screw is tightened down. The solution is to either get some longer bushings. Or if you own a mill like I do you can mill a millimeter fron the top and bottom of the chub where the bushing goes. Then the original bushings will work. That’s what I did. If you look at the original plastic chub the top is milled down. But on the aluminum ones it is not. But once you work out the short bushing issue these steering blocks and chubs are top notch. I’ve been running them really hard the past couple of days with no issues. I would definitely buy from cobra racing again.
Very strong , with beautiful color.
Need a longer bushing to function properly
