Overview
The Traxxas Battery Hold-Down, Tall (2 pcs) is an essential upgrade for RC enthusiasts running the Traxxas low-CG 4x4 chassis platform. Designed specifically for vehicles equipped with the low-centre-of-gravity chassis architecture, these extended battery hold-downs allow you to install taller, multi-cell battery packs without modification to your RC car's structure. Whether you're piloting a Traxxas Slash 4x4 Ultimate LCG short course truck or a Ford Fiesta ST Rally racer, this component represents a significant upgrade to your RC setup's flexibility and performance potential.
If you're serious about maximising your RC car UK performance and want the ability to run larger capacity battery packs like the popular Hobbyking Turnigy NanoTech 6000mAh 3S LiPo cells, this battery hold-down expansion kit is the solution you've been looking for. The product includes both front and rear retainers, providing complete support for taller batteries whilst maintaining the precision engineering that Traxxas is renowned for. This is a genuine Traxxas part (TRX7426X) manufactured to exacting standards, ensuring compatibility and reliability across multiple vehicle platforms within the low-CG chassis family.
The extended battery hold-down design represents a practical upgrade that transforms your RC car's capability without requiring a complete chassis conversion. By accommodating taller batteries, you gain access to higher capacity multi-cell packs that deliver extended runtimes and improved power delivery during basking sessions or competitive racing. RC enthusiasts across the UK have discovered that this upgrade opens up new possibilities for battery management and vehicle performance tuning.
Key Features
- Extended Height Design — The tall configuration of these battery hold-downs is specifically engineered to accept taller, multi-cell battery packs that would not fit with standard hold-down systems, giving you flexibility in battery selection and capacity options for your low-CG chassis vehicle.
- Front and Rear Retainers Included — Each pack contains both front and rear retainers, providing complete battery mounting security from all angles and ensuring your battery pack remains stable during aggressive driving and challenging terrain.
- Low-CG Chassis Compatibility — Specifically designed for Traxxas low-centre-of-gravity 4x4 platforms including the Slash 4x4 Ultimate LCG and Ford Fiesta ST Rally models, maintaining the precise weight distribution and handling characteristics these chassis are engineered to deliver.
- Dual-Pack Quantity — The package includes two complete hold-down assemblies, providing you with spares or allowing you to upgrade multiple vehicles simultaneously within your RC car collection.
- Higher Capacity Battery Support — Enables the use of significantly larger capacity battery packs such as 6000mAh and higher multi-cell LiPo batteries, extending your driving time and improving overall vehicle performance.
- Direct Retainer System — The integrated front and rear retainer design eliminates excessive fiddling with fasteners compared to older HCG (high centre-of-gravity) hold-down systems, making battery changes quicker and more straightforward.
- Genuine Traxxas Component — As an official Traxxas part, this component integrates seamlessly with your existing Traxxas RC setup and maintains the manufacturing quality standards you expect from the world's leading RC manufacturer.
Technical Performance
The Traxxas Battery Hold-Down, Tall represents precision engineering designed to work within the low-CG 4x4 chassis architecture. These extended battery hold-downs are constructed to withstand the demands of RC driving whilst supporting significantly taller battery packs than standard systems. The front and rear retainer design provides comprehensive battery mounting security, essential when running high-capacity multi-cell batteries such as 3S LiPo packs with capacities reaching 6000mAh and beyond. The low-CG platform maintains a lower centre of gravity compared to standard chassis configurations, and these hold-downs are precisely engineered to work within this geometry without compromising handling or weight distribution. The direct retainer system reduces the complexity of battery installation compared to earlier hold-down designs, particularly when working with batteries of varying heights. User feedback confirms that these hold-downs work exceptionally well with larger capacity Hobbyking Turnigy NanoTech battery packs, a popular choice among RC enthusiasts across the UK. The engineering is straightforward yet effective, with no flexibility required for different battery heights — the hold-down accommodates the extended dimensions naturally. These are compatible with the Traxxas Ford Fiesta ST Rally VXL in green, the Traxxas Ford Fiesta ST Rally BL-2S in red, and the Traxxas Slash Ultimate 4x4 VXL in orange, making them universally valuable for owners of these popular 1/10 scale short course and rally platforms.

Frequently Asked Questions
- Which RC vehicles are compatible with the Traxxas TRX7426X tall battery hold-down? — These hold-downs are designed specifically for Traxxas vehicles equipped with the low-CG 4x4 chassis. Compatible models include the Traxxas Slash 4x4 Ultimate LCG 1/10 scale short course truck, the Ford Fiesta ST Rally VXL in green, and the Ford Fiesta ST Rally BL-2S in red. The product does not fit standard chassis vehicles, so verify your vehicle is a low-CG model before purchasing. If you own a standard (non-LCG) chassis vehicle and want to upgrade to accept taller batteries, you will need the complete 7421 conversion kit instead.
- What battery capacity can I run with these tall hold-downs? — The extended design allows you to install significantly taller, multi-cell battery packs compared to standard hold-downs. Users have successfully run 6000mAh capacity 3S LiPo batteries (such as Hobbyking Turnigy NanoTech packs) with these hold-downs, providing extended runtimes and improved power delivery during driving sessions. The exact capacity you can accommodate depends on your specific battery pack dimensions.
- How do these compare to standard battery hold-downs? — The key difference is height capacity. Standard hold-downs accommodate typical battery pack dimensions, whilst these tall extended versions support taller multi-cell batteries. Additionally, the LCG version features a direct retainer system that reduces complexity compared to older HCG (high centre-of-gravity) hold-down designs, though some users note there is less flexibility for varying battery heights with the LCG system compared to the older HCG version.
- Is installation straightforward? — These are replacement components that install directly into your low-CG chassis vehicle. The integrated front and rear retainer design is designed to be more straightforward than fastener-heavy systems, making battery swaps quicker and easier. However, this is a technical component, so familiarity with your vehicle's chassis architecture is helpful.
- Can I use these on a standard (non-LCG) Traxxas vehicle? — No, these are specifically engineered for low-CG 4x4 chassis platforms and will not fit standard chassis vehicles. If you own a standard Traxxas vehicle and want to install taller batteries, contact Traxxas support or consult your vehicle's manual for appropriate options.
- Why would I need two battery hold-down sets? — The product comes with two complete assemblies (2 pcs), allowing you to replace hold-downs on multiple vehicles or maintain spares for your collection. Many RC enthusiasts own several low-CG Traxxas vehicles, making the dual pack a practical choice.
