Overview
The Traxxas Battery hold-down (3) / battery clip / hold-down post / screw pin / pivot post screw (TRX6726X) is an essential upgrade kit for owners of first-generation Traxxas Rustler 4x4 RC trucks who want to expand their battery compatibility. This complete hold-down assembly enables your RC car UK enthusiasts to transition from traditional hump-style NiMH 7-cell batteries and short LiPo packs to modern long-format battery configurations. Whether you're running a Rustler 4x4 or Rustler 4x4 VXL brushless RC model, this upgrade kit provides everything needed to secure larger batteries safely within your chassis, opening up new possibilities for extended runtime and improved performance on the track or trail.
This hold-down set is specifically designed to work with the updated 162mm battery tray found in second-generation Rustler 4x4 models, allowing you to use flat 7-cell NiMH batteries and larger LiPo packs that were previously incompatible with older chassis configurations. The kit includes multiple battery straps to accommodate different battery dimensions, ensuring a perfect fit regardless of your chosen battery type. For anyone looking to modernise their ready-to-run RC Rustler or maximise their RC car investment by using a wider range of battery options, this Traxxas spare part represents an affordable and practical solution that maintains the structural integrity and safety of your model.
RC Model Shop stocks genuine Traxxas replacement parts and upgrades, making it easy for UK RC enthusiasts to keep their vehicles in peak condition and continuously improve their setup. This hold-down assembly is a recognised upgrade path for Rustler owners who want to access the benefits of longer-lasting battery packs without purchasing an entirely new vehicle or upgraded chassis.
Key Features
- Complete hold-down assembly set — This kit includes everything required to securely mount long-format batteries in your Rustler 4x4 RC truck, comprising a battery clip, hold-down post, pivot post screw, and multiple battery straps for flexible battery compatibility.
- Three battery strap options — The set includes three different battery straps, allowing you to select the one that best fits your specific battery dimensions and ensuring a snug, secure hold regardless of whether you're using flat 7-cell NiMH packs or short LiPo configurations.
- Pivot post and screw pin system — The innovative pivot post design allows the battery strap hinge to rotate smoothly, making it easy to install and remove batteries without damaging the electrical connectors or exposing internal wiring, whilst the screw pin provides secure fastening.

Technical Performance
The Traxxas Battery hold-down (3) assembly represents a carefully engineered solution to a common limitation faced by early Rustler 4x4 owners. The original first-generation Rustler 4x4 chassis featured a battery tray designed specifically for hump-style NiMH 7-cell batteries and short LiPo packs, limiting battery options and run time for dedicated RC enthusiasts. This hold-down kit, when used in conjunction with the upgraded 6723R chassis featuring a 162mm battery compartment, allows the accommodation of flat 7-cell NiMH batteries and longer LiPo configurations that offer improved weight distribution and extended runtime. The battery clip component securely mounts to the chassis using existing screw holes, whilst the pivot post system attaches through the underside of the chassis to support a hinged battery strap assembly. This design provides multiple points of contact to distribute the weight of heavier long-format batteries evenly across the chassis structure, preventing stress concentration on any single fastening point. The inclusion of three differently sized straps recognises that battery manufacturers produce packs in varying dimensions, and the kit's flexibility ensures that whether you're using a tight-fitting flat pack or a slightly bulkier configuration, you'll achieve a secure mounting without excessive force that could crack the strap or damage battery terminals. The Traxxas engineering team has designed this system to work seamlessly with the brushless electronics found in VXL models, ensuring that high-discharge modern LiPo batteries can be safely mounted and reliably powered through the existing ESC and motor setup.

Frequently Asked Questions
- Is the Traxxas Battery hold-down compatible with my Rustler 4x4? — Yes, this TRX6726X kit is designed specifically for Traxxas Rustler 4x4 and Rustler 4x4 VXL models, including both the Rustler Ultimate VXL 4x4 variants. It's particularly valuable as an upgrade for first-generation Rustler 4x4 owners looking to expand their battery options.
- What batteries can I use with this hold-down after installation? — Once installed with the upgraded 6723R chassis, this hold-down assembly accommodates flat 7-cell NiMH batteries and long-format LiPo packs that fit within the 162mm battery tray. The three included straps allow you to select the perfect fit for your chosen battery, whether you prefer traditional NiMH chemistry or modern LiPo technology.
- How difficult is the installation process? — Installation requires only basic mechanical skills and standard metric hex wrenches (2.0mm and 2.5mm). The Traxxas support documentation provides step-by-step guidance, and the fastening system uses standard Traxxas components that integrate seamlessly with your RC truck. Most experienced RC enthusiasts can complete the installation in under an hour.
- Can I use this hold-down without upgrading my entire chassis? — This hold-down set is specifically designed to work with the 6723R upgraded chassis featuring the 162mm battery compartment. Whilst you could potentially use the clip component on your existing first-generation chassis, you would not gain the ability to accept long-format batteries without also upgrading to the new chassis configuration.
- Will this improve the performance of my Rustler 4x4 RC truck? — Yes, by allowing you to use longer-lasting battery packs, this upgrade enables extended run times and the ability to choose from a wider range of battery options, including high-discharge LiPo packs that can power brushless VXL motors more efficiently than traditional NiMH batteries.
- Are multiple battery straps really necessary? — The three included straps accommodate different battery dimensions and chemistries. Whether you choose flat NiMH packs, compact LiPos, or longer configurations, having three options ensures you can select the strap that provides the most secure fit without over-tightening, which could damage battery terminals or the strap itself.
