RPM Rear Bulkheads for the T-Maxx & E-Maxx bulkheads, combined with our 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 stripping or 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. RPM bulkheads are stock replacement parts. Each set of bulkheads is sold in pairs and molded in either black or blue and backed by our world-renowned limited lifetime breakage warranty. RPM molded products are proudly designed and manufactured right here in the USA!
