Traxxas E-Revo 2.0 Tubes 5.0mm Toe Links feature a hybrid design that combines steel threaded inserts, inside a 7075-T6 aluminum shaft. This configuration makes these links lighter than the stock steel parts, but stronger than titanium. Package includes two links, four front link rod ends and four rear link rod ends with hollow balls installed, and an aluminum wrench for adjustment, allowing you to build two links that can be used in the front or rear position.
