TUBES 67 mm (center to center) aluminum front camber links are lighter than steel and stronger than titanium. The secret lies in their unique hollow tube design which maximizes rigidity while reducing weight. Made from high-grade 7075-T6 aluminum, TUBES feature a brilliant anodized finish for extra style. A machined groove identifies the left-hand threads and the included aluminum wrench helps prevent marring while adjusting the turnbuckles. TUBES come assembled with rod ends and hollow balls.
