TUBES 128 mm aluminum turnbuckles 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 handy machined groove identifies the left-hand threads and the included aluminum wrench helps prevent marring while adjusting the turnbuckles. Fits Revo® and Summit front or rear.
