This is an optional black RPM Traxxas Maxx Rear Bulkhead Set. RPM Rear Bulkheads further improve the durability of the awesome Maxx monster trucks! Each RPM rear bulkhead follows the same design criteria used to build the front bulkheads – superior materials, impact resistant design changes and lock-nuts to help prevent critical screws from backing out. All this in a part that weighs exactly the same as the stock rear bulkheads!
NOTE: RPM T-Maxx & E-Maxx bulkheads are stock replacement parts and fit all versions of these trucks, from the original T-Maxx 1.5 to the most modern versions of the 3.3 T-Maxx and Brushless edition E-Maxx.
