Technical Performance
The rear lower bulkhead is a fundamental structural component within the XRT chassis architecture, responsible for maintaining precise motor mount alignment and chassis rigidity during extreme driving conditions. Manufactured from high-quality materials using Traxxas' proven engineering methodology, this bulkhead assembly ensures that the motor maintains perfect alignment with the drivetrain, critical for consistent performance and long component lifespan. The inclusion of four steel motor mount washers represents a significant durability advantage, as steel provides superior hardness and resistance to deformation compared to plastic or composite alternatives. These washers distribute clamping force more evenly across the motor mounting interface, preventing the motor from shifting under the intense acceleration and cornering forces typical of high-performance RC buggies. The four 4x18mm button cap screws are precision-engineered fasteners that provide secure assembly while maintaining the aesthetic and functional integrity of your XRT. Steel construction throughout ensures this assembly can withstand repeated assembly and disassembly cycles without degradation. The bulkhead's precise tolerances guarantee perfect fitment with other XRT components, maintaining the chassis geometry that Traxxas engineers have optimised for balanced handling characteristics. This replacement part is essential for maintaining your XRT's performance whether you drive an XRT Ultimate model or the VXL-8S variant, both recognised as serious platforms for dedicated UK RC car enthusiasts.

Frequently Asked Questions
- Is this the correct replacement bulkhead for my XRT? — Yes, this is the genuine Traxxas rear lower bulkhead (part number TRX7827R) designed specifically for XRT Ultimate and XRT VXL-8S models. It is the correct OEM replacement component for these platforms.
- What is the difference between steel and plastic motor mount washers? — Steel washers are significantly harder and more resistant to deformation than plastic alternatives. Under the extreme clamping forces and vibration generated during high-speed RC driving, steel washers maintain their shape and more evenly distribute mounting force, preventing motor shift and ensuring consistent performance. Steel washers are the premium choice for serious RC enthusiasts.
- Will this bulkhead fit other Traxxas models? — No, this component is specifically engineered for XRT Ultimate and XRT VXL-8S models. Using it on other Traxxas RC vehicles may result in poor fitment and performance issues. Always verify compatibility with your specific model before ordering spares.
- Why is a replacement bulkhead needed? — The rear lower bulkhead can sustain damage from crashes, aggressive driving, or general wear and tear. A damaged or bent bulkhead compromises chassis geometry and motor alignment, degrading handling and potentially causing drivetrain problems. Replacing it with a genuine Traxxas component restores your XRT to factory performance specifications.
- Are the fasteners and washers included? — Yes, this replacement assembly includes everything needed for installation: four steel motor mount washers and four 4x18mm button cap screws (BCS). You do not need to purchase additional hardware separately.
- Is this suitable for beginners? — This is a replacement spare part designed for owners of XRT Ultimate or XRT VXL-8S vehicles who need to perform maintenance or repair. If you are new to RC cars and do not yet own an XRT, you should first select a ready-to-run RC buggy suitable for your skill level. Once you own an XRT, this part will be invaluable for maintaining it.
- What tools do I need to install this bulkhead? — Installation typically requires basic RC tools such as hex drivers compatible with the button cap screw heads. Consult your XRT manual for detailed assembly instructions specific to your model variant.
