Overview
The Traxxas Chassis TRX7422-GRAY is a premium replacement chassis designed for serious RC enthusiasts who demand the best performance from their 1/8 scale 4WD buggies. This grey low-CG chassis represents Traxxas engineering at its finest, offering a direct replacement solution for the previous generation 7421 chassis conversion kit or for owners of 4X4 Slashes equipped with a Low-CG chassis. Whether you're looking to upgrade your existing RC car UK setup or rebuild your Jato 4X4 after intense racing, this chassis delivers the platform you need for competitive performance and reliability.
Built specifically to reduce the centre of gravity and improve handling characteristics, this chassis is engineered to enhance cornering stability and reduce body roll during aggressive driving. The low-CG design means your RC buggy will respond more precisely to driver inputs, making it ideal for both track racing and bashing scenarios. If you're serious about RC car performance and want a genuine Traxxas replacement chassis that fits seamlessly into your existing model, the TRX7422-GRAY delivers proven engineering backed by decades of RC innovation.
This is an accessory part suitable for the Jato 4X4 VXL model and a direct replacement for the Jato 4X4 Brushless Accessory line. With compatibility across multiple Traxxas brushless buggy models, this chassis offers versatility for builders and upgraders. RC Model Shop stocks this genuine Traxxas spare part, ensuring you receive an authentic component that meets manufacturer specifications and quality standards.
Key Features
- Low-CG Design — The centre of gravity is lowered through careful engineering, which dramatically improves handling balance and reduces body roll during cornering, making your RC vehicle more responsive and predictable at speed.
- Direct Replacement Compatibility — This grey chassis serves as a direct replacement for the 7421 chassis conversion kit, meaning it drops straight into existing Traxxas 4X4 Slash models or Jato 4X4 builds without requiring extensive modification or additional components.
- Genuine Traxxas Engineering — Manufactured by Traxxas, a leading name in RC vehicles, this chassis benefits from the brand's reputation for precision engineering, durability testing, and performance optimisation across their entire RC car range.
- Grey Colour Option — The distinctive grey finish provides excellent visual contrast and professional appearance, allowing your RC buggy to stand out on the track or trail whilst maintaining the aesthetic integrity of your Traxxas model.
- Proven 4WD Platform — Designed for 4WD operation, this chassis distributes power and traction across all four wheels, providing superior off-road capability and handling balance compared to 2WD alternatives.
- Accessory Part for Multiple Models — Compatible with both the Jato 4X4 Brushless and Jato 4X4 VXL variants, this chassis provides upgrade and replacement options for customers with either brushless platform.
Technical Performance
The Traxxas Chassis TRX7422-GRAY represents a focused engineering solution for high-performance 4WD RC buggies. The low-CG chassis configuration directly impacts vehicle dynamics by shifting weight distribution lower to the ground, reducing the moment arm that causes body roll during cornering. This means faster corner entry speeds, improved mid-corner stability, and more predictable exit acceleration. Built from materials engineered to Traxxas specifications, the chassis provides the rigid platform necessary for transmitting power cleanly from the brushless motor systems found in compatible Jato 4X4 models. The grey colour is not merely aesthetic—it helps differentiate this upgrade from older 7421 chassis models, making it easy to identify the newer, improved platform when examining spare parts or rebuilding vehicles. As a direct replacement component, the TRX7422-GRAY maintains compatibility with the existing suspension geometry, drivetrain components, and electronics found in Traxxas 4X4 Slash and Jato 4X4 models, ensuring seamless integration without hidden costs or modification requirements.

Frequently Asked Questions
- What models does the Traxxas Chassis TRX7422-GRAY fit? — This chassis is designed as a direct replacement for the 7421 chassis conversion kit and is compatible with 4X4 Slash models equipped with low-CG configuration. It's also listed as a replacement part for Jato 4X4 Brushless models and as an accessory part for the Jato 4X4 VXL. Specifically, it's compatible with the TRX90154-4 series (Jato 4X4 BL-2S in black, red, green, and blue) and the TRX90386-4 series (Jato 4X4 VXL 1/8 4WD in green, orange, blue, and pink).
- What is a low-CG chassis and why should I upgrade to one? — Low-CG stands for Low Centre of Gravity. By positioning the chassis lower, the vehicle's weight distribution is optimised to reduce body roll during cornering and high-speed turns. This results in better handling, faster corner speeds, improved stability, and a more predictable driving experience—benefits that matter whether you're racing on track or bashing off-road.
- Is this a direct bolt-on replacement? — Yes, the TRX7422-GRAY is engineered as a direct replacement for the 7421 chassis, meaning it should fit into existing 4X4 Slash and compatible Jato 4X4 models without requiring additional modifications or extra components to be purchased.
- What colour options are available? — The TRX7422-GRAY is available in grey. Traxxas may offer this chassis in other colours through different part numbers, but this specific product is the grey variant.
- Do I need any additional parts to install this chassis? — As a chassis replacement, you'll need to transfer your existing drivetrain, suspension, electronics, and body from your old chassis. The TRX7422-GRAY is the chassis platform only—it does not include motor, ESC, battery, radio system, or body panels.
- Is this suitable for beginners? — This is a replacement chassis component designed for those already familiar with RC car assembly and maintenance. It's ideal for upgraders, racers, and hobbyists who want to improve their existing vehicle's performance. Beginners should start with a complete ready-to-run RC vehicle before considering chassis upgrades.
