This is the RDLogics Heavy-Duty Silver Aluminum Rear Bumper assembly for the Traxxas Revo 2.5 and 3.3 trucks.  These are very strong, and they look awesome.  There are aluminum bumper brackets available for these.  These are some of the nicest Revo bumpers available.

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.
