TUBES 144 mm (center to center) aluminum toe 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 10 mm aluminum wrench helps prevent marring while adjusting the turnbuckles. TUBES are sold in pairs and come with rod ends and hollow balls.
