Frequently Asked Questions
- What is the front lower bulkhead and why do I need one for my Traxxas X-Maxx? — The front lower bulkhead is a structural chassis component that supports your suspension mounting points and drivetrain alignment. It's subjected to tremendous stress during off-road driving, jumping and high-speed running. If your bulkhead becomes bent, cracked or damaged, it will compromise your truck's handling and suspension geometry. Keeping a genuine replacement on hand ensures you can quickly restore your X-Maxx to factory performance specifications when needed.

- How often should I expect to replace the front bulkhead? — Under normal recreational use, your front lower bulkhead should last for extended periods. However, aggressive bashing, hard impacts, jumps and racing will increase wear. Many experienced RC enthusiasts keep spare bulkheads available so they can replace damaged components immediately and continue running without waiting for repairs.

If you suspect damage, a replacement will restore your truck to like-new performance.
