Overview
The Traxxas Shock Tower Rear (Left & Right Halves) TRX8939X is an essential replacement chassis component designed for serious RC enthusiasts who demand precision engineering and durability from their scale models. This OEM Traxxas spare part is purpose-built to restore your RC short course truck to factory specifications, ensuring optimal suspension performance and structural integrity. Whether you're a competitive racer pushing your Maxx Slash to its limits or a weekend basher who wants to maintain peak performance, this shock tower replacement is the genuine solution recommended by Traxxas engineers themselves.
The rear shock tower is a critical structural element of your RC vehicle's chassis, providing the mounting points for your suspension system and transmitting forces from the track directly through the vehicle frame. Over time, through aggressive driving, impacts, and general wear and tear, shock towers can become damaged, bent, or cracked, compromising your vehicle's handling characteristics and suspension geometry. Having access to genuine OEM replacement parts like this TRX8939X ensures you can quickly restore your truck to optimal performance without compromising on build quality or compatibility with other Traxxas components. This is the professional choice for UK-based RC hobbyists who understand that using genuine manufacturer parts is crucial for maintaining reliability and performance.
If you're searching for authentic Traxxas spare parts in the UK, this shock tower represents the quality standard you should expect. RC Model Shop stocks genuine Traxxas components that meet exacting OEM specifications, giving you confidence that you're purchasing parts engineered and tested by the brand's own technicians.

Technical Performance
The Traxxas Shock Tower Rear represents the culmination of decades of RC engineering expertise, incorporating design features that maximise structural rigidity whilst maintaining optimal weight distribution. The dual-half design allows for efficient assembly and disassembly, making maintenance and repair straightforward for RC modellers of all experience levels. The shock tower serves as the backbone of your suspension system, positioning your shocks at precise angles that have been dynamically tested and refined by Traxxas engineers to deliver consistent handling across various racing conditions. The material composition has been carefully selected to provide excellent impact resistance—crucial when running on high-grip asphalt, loose dirt, or mixed terrain surfaces. By maintaining the factory geometry and material specifications of this genuine OEM part, you ensure that your Maxx Slash or Slash maintains the performance characteristics that made it competitive from the factory. Whether you're running 6S LiPo batteries with brushless powertrains generating substantial forces, or pushing your truck through technical terrain, this shock tower provides the structural foundation needed to transmit power efficiently whilst protecting your suspension components from damage.

Frequently Asked Questions
- Is the Traxxas Shock Tower Rear TRX8939X compatible with my Maxx Slash? — Yes, this genuine OEM part is specifically engineered for all 1/8 4WD Maxx Slash models. It will work seamlessly with any of the colour variants or special editions of the Maxx Slash, as well as compatible Slash platforms that use identical chassis geometry.
- How do I know if I need to replace my shock tower? — Signs that you may need a replacement include visible cracks or breaks in the plastic, bent or twisted shock tower halves that affect suspension geometry, shock mounts that are loose or unstable, or noticeable changes in your vehicle's handling or suspension performance that aren't explained by worn tyres or damaged shocks.
- What are the advantages of using genuine Traxxas parts versus aftermarket alternatives? — Genuine OEM Traxxas parts are engineered to exact specifications using the same materials and tolerances as original components. This guarantees perfect fitment, maintains your vehicle's performance characteristics, preserves resale value, and provides confidence that you're using parts tested by the manufacturer's engineers. Aftermarket alternatives may have slightly different dimensions or material properties that can affect handling.
- Can I repair a cracked shock tower or do I need to replace it completely? — Whilst some minor cracks might be repairable with super glue or plastic epoxy in an emergency, a genuine replacement is strongly recommended for the best results. Repaired sections weaken the structural integrity of the chassis, potentially causing failures under high-stress conditions. Since replacement shock towers are relatively inexpensive compared to potential damage to other components, replacement is the professional approach.
- How difficult is it to install the shock tower myself? — Installing this shock tower requires basic mechanical skills and standard RC tools including screwdrivers and a hex key set. The two-half design makes installation straightforward, though you'll need to carefully position your shocks and ensure all fasteners are tightened to proper specifications. If you're uncomfortable with mechanical work, we recommend consulting the official Traxxas manual or visiting our RC Model Shop in Walsall where our expert team can advise on installation.
- Does this part come painted or does it require colour matching to my truck? — This is an OEM plastic chassis component that comes in standard Traxxas black finish. It does not require painting as it's internal to the chassis and not visible on the completed vehicle. However, if you've customised your truck's aesthetics, you can paint this component to match using plastic-compatible paint.
