Traxxas Battery Hold-Down Extended Front Rear Retainer 1/10 LCG TRX9628

Overview

The Traxxas Retainer, battery hold-down (front and rear) is an essential upgrade for RC enthusiasts running Traxxas low-CG 4X4 chassis platforms in the UK market. This extended battery hold-down system with integrated front and rear retainers is specifically engineered to accommodate taller, multi-cell battery packs, giving you greater flexibility in power management and performance tuning for your 1/10 scale RC car or truck. Whether you're a seasoned basher looking to maximise run time or a weekend racer seeking competitive advantage, this Traxxas component delivers the reliability and precision engineering you expect from the world's leading RC manufacturer.

Designed for use with the Traxxas Ford Fiesta ST Rally and Traxxas Slash 4x4 Ultimate LCG 1/10 scale short course truck, this battery hold-down replaces the standard low-CG chassis retainer and enables installation of higher-capacity batteries without modification to your vehicle. The extended design maintains the low centre of gravity benefits of the LCG platform whilst accommodating battery packs up to significantly taller dimensions than standard hold-downs allow. This makes the Traxxas battery hold-down retainer an ideal upgrade for UK RC enthusiasts seeking greater versatility from their low-CG equipped vehicles, enabling genuine 6000mAh and larger 3S LiPo packs to fit securely without compromise.

As an authorised Traxxas retailer serving the UK RC community, RC Model Shop stocks this genuine OEM component to ensure you receive the authentic part with full manufacturer backing and compatibility guarantee. Order with confidence knowing you're upgrading your RC short course truck or rally car with factory-engineered components.

Key Features

• Extended Battery Accommodation — The hold-down extends vertically to accept taller multi-cell battery packs, allowing you to run high-capacity 6000mAh 3S LiPo batteries that would not fit in the standard low-CG hold-down, directly increasing your run time without sacrificing the low centre of gravity chassis benefits.
• Integrated Front and Rear Retainers — This single component includes both front and rear battery retainers in one assembly, simplifying installation and reducing the number of parts required whilst ensuring secure battery mounting at both ends of the chassis.
• Low-CG Chassis Compatibility — Specifically engineered for Traxxas low-CG 4X4 chassis platforms, this hold-down maintains the centre of gravity advantage that defines the LCG architecture, preserving handling characteristics and performance benefits.
• OEM Traxxas Engineering — Manufactured to factory specifications using Traxxas quality standards, this is the genuine replacement part rather than an aftermarket alternative, guaranteeing fit, finish and durability across multiple bash sessions.
• Rally and Short Course Truck Optimisation — Developed specifically for the Traxxas Ford Fiesta ST Rally BL-2S, Fiesta ST Rally VXL and Slash Ultimate 4x4 VXL platforms, this hold-down is engineered to these exact vehicle geometries and requirements.
• No Chassis Conversion Required — Works with existing low-CG 4X4 chassis without requiring full chassis conversion kits, making this an affordable and practical upgrade for owners seeking greater battery flexibility.

Technical Performance

The Traxxas battery hold-down retainer system represents genuine OEM engineering for low-CG 4X4 platforms. Built with quality engineering to match your Traxxas vehicle's reliability standards, this component is constructed to withstand the mechanical loads, vibration and impact that occur during aggressive driving. The extended vertical design accommodates battery packs significantly taller than the standard low-CG retainer, enabling use of multi-cell LiPo configurations including the popular 6000mAh 3S Turnigy NanoTech packs and equivalent capacity batteries from other manufacturers. The integrated front and rear retainer design provides dual-point battery mounting for maximum security and stability during high-speed running. Installation on compatible Slash 4x4 and Rally platforms requires no additional modifications beyond replacing the factory low-CG hold-down, making this an accessible upgrade for UK RC hobbyists. The system maintains the critical low centre of gravity advantage of LCG chassis engineering whilst expanding battery capacity options, delivering genuine performance flexibility for both racing and bashing applications across the UK RC scene.

Frequently Asked Questions

• Which Traxxas vehicles is this battery hold-down compatible with? — This extended battery hold-down is designed for Traxxas low-CG 4X4 platforms including the Traxxas Ford Fiesta ST Rally BL-2S, Ford Fiesta ST Rally VXL, and Slash Ultimate 4x4 VXL 1/10 scale short course truck. It is not compatible with standard high-CG chassis vehicles, so verify your platform before ordering.
• What size batteries can this hold-down accommodate? — The extended design accommodates taller battery packs than standard low-CG retainers, enabling use of high-capacity multi-cell batteries including 6000mAh 3S LiPo packs from manufacturers like Turnigy NanoTech. Exact maximum dimensions depend on your specific vehicle platform, but the primary benefit is tall-format battery compatibility.
• Do I need to purchase anything else to use this hold-down? — You will need the compatible Traxxas low-CG 4X4 vehicle platform and a battery pack. For a complete low-CG chassis conversion on other Traxxas vehicles, Traxxas offers the full conversion kit 7421, though this hold-down works as a standalone upgrade on already-compatible platforms.
• Is installation difficult? — Installation involves replacing your existing standard low-CG hold-down with this extended retainer assembly. The process is straightforward for experienced RC builders and should present no complications for anyone familiar with basic Traxxas maintenance and tuning.
• Will this improve my run time? — Yes, the primary advantage of this extended hold-down is enabling larger capacity batteries that would not fit in the standard retainer. By upgrading to a higher capacity 3S LiPo, you can expect significantly longer run times between charges.
• Is this suitable for competitive racing or casual bashing? — This component is suitable for both uses. Competitive racers benefit from the flexibility to tune battery capacity and weight distribution for specific track conditions, whilst casual bashers gain extended run time for longer play sessions.
