Avid XB2 titanium ball stud kit
Coming from Avid and made for the Xray XB2 2WD off-road buggy is a titanium ball stud kit. The 14-piece set includes high-quality 4.9mm billet 6Al-4V titanium ball studs to minimise weight without sacrificing strength. The ball studs sport a 2mm allen head on top of the ball for easy removal and they are about 40 percent lighter than the kit steel ball studs.
