This is a set of optional blue ST Racing Concepts Steering Knuckles for the Traxxas Revo monster truck. Precision CNC Machined from high quality aluminum, our steering knuckles for the Traxxas Revo features all the details of the stock plastic pieces faithfully CNC machined, and with improved durability with the larger 6x15mm outer bearing (included). Also compatible with the new E-Maxx and the T-Maxx 3.3. We believe this is arguably one of the best CNC machined, high quality steering knuckle on the market for your Traxxas monster trucks.
These are great! My only problem is they did not come with metal screws to hold in the ball joint. I had to use the plastic ones that came with the revo. The one they sell for the 1/16 revo comes with them
