The Bulkheads on the T-Maxx & the E-Maxx tend to break under impact due to lack of support. That's why RPM has designed these braces to add much needed support by tying the bulkheads together. When the bulkheads are supported with our braces, not only will breakage of the bulkheads decrease, strength will be added to both the front & rear of the vehicle and much of the chassis flex attributed to bulkhead flex will be eliminated!. In addition, our front brace has been elongated to add dirt & debris protection for the front differential area. Eight, black 4-40 machine screws are included with these braces for the ultimate in strength! Available in three popular colors, Black, Blue, & Purple (all of which match our molded T-Maxx/E-Maxx A-arms perfectly). Sold with one front bulkhead brace and one rear brace in each package, as well as all necessary mounting hardware and instructions for proper mounting.
