This genuine Traxxas spare part has been engineered to the same exacting standards as the original equipment, guaranteeing perfect fitment and reliable performance with your 1/10 scale electric stadium truck.
As a critical structural component, the upper chassis forms the backbone of your Rustler HD's frame.

Having the right spare parts available means less downtime and more time enjoying your ready to run RC stadium truck on the track, field or off-road terrain.
Key Features
- Genuine Traxxas Original Equipment — This upper chassis is manufactured by Traxxas to the exact same specifications as the chassis fitted to factory-built Rustler HD trucks, ensuring perfect compatibility and reliable performance with zero fitment issues.
- Black Finish — The durable black coating provides a professional appearance whilst protecting the underlying material from weathering and minor abrasion during use and storage.
- Broad Model Compatibility — This single chassis component works with both the Rustler HD XL-5 electric models and the higher-performance Rustler HD BL-2S brushless variants, across green, pink, orange and red body colours, making it a versatile spare part for any Rustler HD owner.
- Critical Structural Component — The upper chassis forms the main structural element of your RC stadium truck's frame, directly affecting handling, durability and overall performance during aggressive bashing and racing.
- Replacement and Upgrade Option — Whether replacing a damaged chassis or simply upgrading to factory-fresh condition, this part restores your Rustler HD to like-new structural integrity.
Technical Performance
The Traxxas Upper Chassis TRX3729-BLK is engineered with the same precision and material science that Traxxas applies to all its chassis components, ensuring it delivers the structural rigidity and durability required for modern 1/10 scale electric stadium truck operation. As the upper structural frame element of the Rustler HD platform, this chassis must support the weight of the motor, ESC, battery and suspension whilst absorbing impacts and maintaining precise geometry under cornering loads. The black finish is applied to a robust base material designed to resist the repeated stress of acceleration, braking and lateral forces that RC stadium trucks experience during enthusiastic bashing sessions. When properly installed on a Rustler HD XL-5 or BL-2S model, the upper chassis works in concert with the lower frame sections to create a strong, reliable foundation for all downstream components including the brushless motor systems, electronic speed controllers and suspension assemblies found in these popular 1/10 electric RC trucks.

Frequently Asked Questions
- Which Traxxas Rustler HD models is this upper chassis compatible with? — The TRX3729-BLK upper chassis is compatible with all Traxxas Rustler HD models, specifically including the Rustler HD 1/10 Electric XL-5 2WD RTR Stadium Truck available in green, pink, orange and red colour variants, and the Rustler HD BL-2S 1/10 Electric 2WD RTR Stadium Truck available in blue, orange, green and red. If you own any Rustler HD variant, this is the correct upper chassis replacement.
- Why would I need a replacement upper chassis for my RC stadium truck? — The upper chassis can become cracked, bent or stress-fractured through heavy bashing, impacts with obstacles, or cumulative wear from aggressive driving. Having a quality replacement chassis available means you can quickly restore your truck to full working condition rather than leaving it sidelined. Additionally, some RC enthusiasts purchase spare chassis components to keep their trucks in like-new condition or to prepare backup rigs for intensive racing sessions.
- Is this a genuine Traxxas part? — Yes, the TRX3729-BLK is an authentic Traxxas OEM (original equipment manufacturer) spare part, not a third-party aftermarket clone.

For serious RC enthusiasts and competitive bashers, genuine parts represent the best value for long-term reliability and performance.
- What is the model number and how do I ensure I order the correct chassis? — The model number is TRX3729-BLK, with the -BLK suffix indicating the black finish.
