Traxxas T-Maxx and E-Maxx optional rear bulkheads for the left and right are made of blue aluminum. This replaces the plastic differential cases in the rear of the truck
Traxxas machined-aluminum bulkheads increase the strength of the T-Maxx. They provide a super-strong foundation for the suspension and chassis and maximum protection against crash damage. They’re CNC-machined from 6061-T6 aluminum and are anodized-brilliant-blue with machined edges for outstanding detail. *NOTE: Installation requires use of 4939X suspension pins. Do not use stock hinge pins to complete this installation.
