Technical Performance

The Traxxas Bulkhead, Rear is engineered from premium injection-moulded plastic that combines impact resistance with minimal weight. This rear chassis component forms the structural backbone of the rear end, housing and protecting the differential assembly whilst maintaining precise geometric tolerances essential for suspension and drivetrain alignment. The inclusion of the differential retainer means the bulkhead actively manages drivetrain performance, ensuring the rear differential remains perfectly centred and aligned during acceleration, deceleration and cornering forces. The 4x14mm ball cup screws provide secure fastening with adequate clamping force to prevent creep or loosening during extended driving sessions or competitive racing. For RC enthusiasts across the UK building or maintaining 1/10 scale vehicles, this component represents the quality and engineering precision that allows Traxxas vehicles to deliver consistent, predictable handling whether you're bashing off-road or competing on the circuit.

Frequently Asked Questions

• What is a rear bulkhead and why do I need this spare part? — The rear bulkhead is the structural component that forms the rear chassis of your RC vehicle, housing the differential and connecting the suspension components. If you've cracked, bent or damaged yours through hard impacts or crashes, replacing it with this genuine Traxxas part restores structural integrity and handling. Many RC enthusiasts also keep spare bulkheads on hand for quick repairs at the track so they can minimise downtime during racing events.
• Will this fit my Traxxas RC vehicle? — This is a genuine Traxxas part designed for specific Traxxas models. We recommend checking your vehicle's manual or contacting our knowledgeable team at RC Model Shop to confirm this part is compatible with your exact model, as different Traxxas vehicles may use different bulkhead specifications.
• Is this a complete rear end replacement? — This bulkhead assembly includes the structural halves, differential retainer and fasteners, giving you the essential components for the rear chassis. Depending on the condition of your vehicle, you may also need to replace other rear components such as differential gears, suspension arms or bearings, but this part provides the core structural element.
• Why does this include a differential retainer? — The differential retainer is a crucial part of proper drivetrain function, keeping the rear differential perfectly aligned and centred within the chassis. Without it, differential movement can cause binding, uneven power distribution and poor handling. Including it with the bulkhead ensures you have everything needed for correct assembly.
• What are 4x14mm ball cup screws? — These are suspension fasteners specifically designed for RC vehicles, featuring a ball-shaped cup end that allows slight angular adjustment whilst maintaining security. The 4mm diameter and 14mm length are precisely matched to the bulkhead design, ensuring proper clamping without stripping threads or failing under load.
• Where can I purchase this spare part in the UK? — RC Model Shop stocks this genuine Traxxas part and can dispatch it quickly so you can get back to racing or bashing. We're an authorised Traxxas retailer with expert knowledge and genuine products at competitive prices.
