RPM Rear Bulkheads for the T-Maxx & E-Maxx, combined with RPM's front bulkheads (RPM #81062 or #81065) are available to further improve the durability of these awesome monster trucks! Each RPM rear bulkhead follows the same design criteria we used to build our 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! Please see our front bulkheads (RPM #81062 & #81065) for additional details.
