This is a set of four (4) RDLogics 'Cross' Red Aluminum Wheel Spinners for the Traxxas Revo 2.5 and 3.3, as well as the T-Maxx 3.3.  These spinners will fit right on the stock Revo 2.5, 3.3, and T-Maxx 3.3 wheels, so there is no need to purchase another full set of wheels.  These are complete with bearings and mounting hardware.

These are very strong, and they look awesome. RDLogics parts are built with the racer in mind, and they are constructed of the highest quality materials. These are a must for high-performance vehicles and people who want the best.
