Frequently Asked Questions

• What is a clipless body mounting system and why should I choose it? — The clipless body mounting system is a modern advancement over traditional screw-down body posts. Instead of using multiple screws to hold the body in place, the clipless system uses specially designed latches and mounts that provide secure attachment with a cleaner appearance. The system is faster to use, easier on your body shell (fewer screw holes means less potential for cracking), and looks more authentic because there are no visible fastener heads disrupting the body lines.
• Is this kit compatible with my TRX-4? — This conversion kit is designed specifically for TRX-4 chassis models with the standard 12.3-inch (312 millimetre) wheelbase. Most TRX-4 models use this wheelbase, but some variants like the Defender and 2021 Ford Bronco feature a longer 12.8-inch (324 millimetre) wheelbase. If you're unsure of your TRX-4's wheelbase, measure the distance between the front and rear axle centres, or consult the documentation that came with your vehicle.
• Do I need any tools to install this conversion kit? — The installation process is straightforward and requires only basic tools, typically a small Phillips screwdriver or similar fastener tools. The kit is designed for user-friendly installation—you simply mount the body latches onto your existing Bigfoot body, then install the new body mounts on your chassis and secure them with the provided hardware. Detailed installation instructions are typically included or available on the Traxxas website.
• Can I use this kit with other TRX-4 bodies or is it specific to Bigfoot? — This conversion kit is specifically designed for the Bigfoot No. 1 body, as it includes mounts and latches engineered for that particular body's geometry and attachment points. Other TRX-4 bodies have different body shapes and mounting requirements, so using this kit with other bodies may result in improper fit or instability. If you want to convert to a different body style, you'll need the appropriate conversion kit for that specific model.
• What happens to my old body posts and mounting system? — If your TRX-4 currently uses traditional screw-down body posts, you can leave them in place on the chassis—they won't interfere with the clipless mounting system. However, if you want a completely clean chassis appearance, you can remove the old posts. The clipless mounts provided in this kit replace the functional mounting role of the old posts, so your body will be held securely without them.
• Is this suitable for beginners? — Yes, this conversion kit is suitable for RC enthusiasts of all experience levels. The installation process is straightforward and doesn't require advanced mechanical knowledge or specialised tools. If you already own a TRX-4 and are comfortable performing basic maintenance or modifications on your RC vehicle, you'll find this conversion kit easy to install. Traxxas provides clear documentation to guide you through the process.
• Will this kit improve the performance of my TRX-4? — This is a body conversion kit, not a performance upgrade. It doesn't change your TRX-4's speed, handling characteristics, or off-road capability. What it does provide is a fresh look with authentic Bigfoot styling and an improved body mounting method that's easier to use and more visually appealing than traditional post systems. The real benefit is cosmetic and functional in terms of ease of use.
• Where can I find installation instructions? — Traxxas provides comprehensive documentation for all their conversion kits. You can typically find detailed installation guides on the Traxxas website, or contact RC Model Shop's experienced team who can provide support and guidance. The instructions walk you through mounting the body latches onto your body shell and installing the mounts on your chassis step by step.
