Lightweight Aluminum Turnbuckles 30% lighter than steel, more than double the strength of titanium! Carbon black TUBES® add a high-tech stealth look to Revo and Maxx trucks. TUBES are 30% lighter than the stock steel toe links, plus they’re 4-times stiffer and more than double the strength of aftermarket titanium! These are the strongest toe links you can buy for your Maxx or Revo. The secret is in the unique patent-pending hollow tube design that maximizes stiffness and resistance to bending, while at the same time reducing weight. The beefy size tells everyone your truck means business. Traxxas TUBES are manufactured from high-grade 7075-T6 aluminum and anodized carbon black. To prevent marring the finish, a metric aluminum wrench is included for adjustment. The broad center nut makes it easy to line up the wrench for fast, trackside tuning. A handy machined groove on one end easily identifies the left hand threads.
