Overview

The Traxxas Battery hold-down and receiver hold-down kit (part number TRX3627X) is an essential upgrade for owners of the Traxxas Stampede VXL, one of the most popular brushless RC monster trucks available in the UK market. This specialist kit allows you to install larger format battery packs into your Velineon powered Stampede VXL, significantly expanding your options for extended runtime and improved performance. Whether you're a weekend basher enjoying your RC car UK hobby or a committed enthusiast looking to maximise your vehicle's potential, this hold-down system provides the secure mounting solution you need to safely accommodate oversized batteries that would otherwise not fit properly in the standard configuration.

Designed and manufactured by Traxxas, a globally recognised leader in ready-to-run RC vehicle engineering, this kit represents a precision-engineered solution to a common limitation faced by Stampede VXL owners. The two-piece design separates the receiver hold-down and battery hold-down functions, allowing maximum flexibility in how you configure your vehicle's internals. By upgrading with this kit, you unlock the ability to use more powerful battery packs, which translates directly to longer run times, better acceleration, and sustained high-speed performance throughout your driving session. This is particularly valuable for serious RC enthusiasts in the UK who demand reliability and performance from their electric brushless RC vehicles.

Perfect for those looking to get the absolute most out of their Stampede VXL investment, this hold-down kit comes complete with all the mounting hardware you'll need, including metal posts and spacers for precise positioning, durable body clips for secure fastening, servo tape for cable management, and an adhesive foam pad to dampen vibration and protect your components. Installation is straightforward, and the finished result is a vehicle that looks factory-finished while delivering significantly improved capability and flexibility.

Key Features

• Two-Piece Design — The battery hold-down and receiver hold-down are engineered as separate components, giving you complete flexibility in mounting larger format batteries whilst maintaining secure receiver positioning, which is essential for reliable signal transmission and vehicle control.
• Larger Battery Compatibility — This kit specifically enables the installation of oversized battery packs into the Velineon powered Stampede VXL, allowing you to extend your running time and improve acceleration significantly compared to standard configurations.
• Metal Posts and Spacers Included — The kit includes two precision metal posts and two spacers that position your batteries and receiver at the optimal height and angle within the chassis, ensuring perfect fitment and preventing movement during aggressive driving.
• Secure Body Clips — Two heavy-duty body clips provide absolutely secure fastening of larger batteries, preventing any shifting or movement even during high-speed runs or rough terrain driving, which is critical for vehicle safety and consistent handling.
• Servo Tape — Included servo tape allows you to route and manage cables neatly, keeping everything organised, protected from damage, and maintaining a clean appearance inside your vehicle's electronics bay.
• Adhesive Foam Pad — The included foam pad dampens vibration transmission between your battery and the vehicle chassis, protecting sensitive electronic components and reducing wear on solder joints and connectors over time.
• Factory Quality Engineering — As an official Traxxas part designed specifically for the Stampede VXL, this kit maintains the same rigorous quality standards and precision fit that Traxxas customers expect from genuine spare parts and upgrades.

Technical Performance

The Traxxas TRX3627X hold-down kit is engineered to withstand the considerable forces generated by the brushless Velineon motor system found in the Stampede VXL, one of the most powerful ready-to-run RC monster trucks on the market in the UK. The metal posts and spacers are manufactured from precision-machined aluminium alloy, providing exceptional strength-to-weight ratio whilst maintaining the vehicle's handling balance. The assembly accommodates larger capacity LiPo battery packs that exceed the dimensions of the standard battery compartment, allowing users to select from a much wider range of battery options to match their desired performance characteristics. The adhesive foam pad works in conjunction with the metal post structure to create a vibration-isolated mounting platform that protects the ESC and receiver from shock damage whilst distributing impact forces more evenly across the vehicle frame. The body clips utilise Traxxas's proven retention design, providing secure fastening that has been tested extensively through thousands of kilometres of off-road driving in conditions ranging from smooth parkland to rocky terrain. This kit represents a thoughtful engineering solution to a genuine user need, enabling owners to maximise the potential of their Stampede VXL investment without compromising reliability or introducing any risk of component damage.

Frequently Asked Questions

• Which Traxxas models is the TRX3627X battery hold-down kit compatible with? — This kit is specifically designed for the Traxxas Stampede VXL equipped with Velineon brushless motor technology. It is intended to work with the 3725X configuration. Always verify compatibility with your specific vehicle variant before purchase, as using the incorrect hold-down kit could result in poor fitment or safety issues.
• Will this kit allow me to use significantly larger batteries in my Stampede VXL? — Yes, that is the primary purpose of this upgrade. The two-piece design and metal post structure have been engineered specifically to accommodate larger format battery packs than the standard battery compartment allows. However, you should verify that your chosen battery dimensions will fit within your vehicle's chassis before purchase.
• Is this suitable for beginners looking to upgrade their ready-to-run RC monster truck? — Absolutely. This is an excellent first modification for RC enthusiasts in the UK looking to enhance their vehicle. Installation requires only basic tools and a small amount of mechanical aptitude. The straightforward design means there is minimal risk of causing damage during fitting, making it ideal for those new to vehicle customisation and upgrades.
• What tools do I need to install this battery hold-down kit? — Installation is designed to be accessible to most users. You will need basic hand tools appropriate for working with small metal posts and fasteners. The adhesive foam pad requires no tools – simply clean the surface and apply as directed. Servo tape can be applied with your hands. Most users report installation taking between fifteen and thirty minutes depending on their experience level.
• Can I use this hold-down kit with any LiPo battery? — The kit accommodates larger format batteries, but physical dimensions remain limited by your vehicle's chassis. Popular larger capacity LiPo batteries suitable for extended runtime in the Stampede VXL will fit with this kit, but you should always verify your specific battery dimensions against available space before purchase. Your RC retailer can advise on compatible battery options.
• Will upgrading to this hold-down kit improve my vehicle's speed or acceleration? — The hold-down kit itself does not directly increase speed. However, by allowing you to use larger capacity batteries, you can select packs with higher discharge rates (measured in C-rating), which will provide more current to your brushless motor system and result in improved acceleration and sustained high-speed performance.
• Is the TRX3627X expensive compared to standard hold-down solutions? — Feedback from users indicates this is a genuine Traxxas solution that delivers exceptional value for the functionality provided. The kit includes all necessary hardware in one package, eliminating the need to source multiple components separately. Pricing is competitive with other manufacturer solutions of equivalent quality.
• Does the adhesive foam pad damage vehicle paint when removed? — The foam pad is designed for semi-permanent application. When carefully removed, it should not damage vehicle paint, though you may wish to test on a small area first. The adhesive is formulated to bond securely whilst remaining removable without leaving residue.
