TRX7863

Overview

The Traxxas Shock shaft, 92mm (GTX) (steel, Chrome finish) (2) (assembled with rod ends & hollow balls) TRX7863 is an essential replacement suspension component for serious RC enthusiasts in the UK who demand reliability and performance from their vehicles. These premium shock shafts are engineered to deliver consistent damping performance and smooth suspension action, whether you're bashing at the weekend or competing at the track. If you own a Traxxas XRT or Funco Motorsports RC model, having genuine Traxxas replacement parts on hand ensures your vehicle stays in peak condition and ready for action.

As a critical suspension component, shock shafts experience significant stress during aggressive driving, jumps and high-speed cornering. The OEM Traxxas shock shaft is precision-engineered to maintain proper geometry and response characteristics that match your vehicle's suspension tuning. Upgrading or replacing worn shock shafts is one of the most cost-effective ways to restore your RC car's performance and handling. Whether you're setting up a new vehicle or maintaining an existing fleet of RC models, these genuine Traxxas parts are the smart choice for UK RC car enthusiasts who refuse to compromise on quality.

Available now at RC Model Shop, these shock shafts come fully assembled with rod ends and hollow balls, so you can install them immediately without additional modifications or assembly work. Compatible with multiple Traxxas models including the XRT VXL-8S, XRT Ultimate, and Funco Motorsports Pro Scale vehicles, this is a must-have spare part for any serious RC collection.

Key Features

• 92mm Length for GTX Shocks — The 92mm dimension is specifically designed for Traxxas medium-length GTX shock bodies, ensuring perfect compatibility and correct suspension geometry on compatible vehicles. Using the correct shock shaft length is critical for maintaining proper ride height and suspension response.
• Steel Construction with Chrome Finish — These shock shafts are manufactured from premium steel with a durable chrome finish that resists corrosion and wear, even when exposed to moisture, dirt and mud during outdoor RC racing and bashing sessions. The chrome plating adds visual appeal whilst providing real functional protection against rust and oxidation.
• Pre-Assembled with Rod Ends and Hollow Balls — Unlike economy shock shafts, these components arrive fully assembled with rod ends and hollow balls already installed, eliminating the need for additional hardware purchases or time-consuming assembly. This saves you money and gets your vehicle back on the track faster.
• Genuine Traxxas OEM Component — This is an authentic Traxxas replacement part designed and manufactured to OEM specifications, guaranteeing perfect fit and performance on compatible Traxxas vehicles. Using genuine parts ensures your suspension behaves exactly as the engineers intended.
• Pair Included — The package contains two complete shock shafts (one pair), sufficient for a complete front or rear suspension refresh on most RC vehicles, or one axle if your model uses four shocks total.

Technical Performance

The Traxxas Shock shaft TRX7863 represents decades of off-road racing engineering excellence. At 92mm in length, this medium-sized shaft is engineered for the GTX shock family, which represents Traxxas's premium suspension platform used across multiple vehicle lines. The steel construction provides the rigidity and durability required for aggressive driving whilst the chrome finish ensures longevity in demanding conditions. The hollow ball design reduces unsprung weight whilst maintaining structural integrity, a key consideration in high-performance RC suspensions where reducing rotational mass improves handling response. The pre-installed rod ends ensure perfect geometry and eliminate potential assembly errors. Whether you're running an XRT VXL-8S in high-speed stadium truck racing, an XRT Ultimate for mixed-terrain bashers, or a Funco Motorsports Pro Scale 8S sand rail, this shock shaft maintains the precise suspension characteristics your vehicle needs. The engineering precision demanded by Traxxas's competition heritage means these shafts maintain consistent performance lap after lap, even under extreme conditions.

Frequently Asked Questions

• Which Traxxas vehicles use these 92mm GTX shock shafts? — These shafts are compatible with the Traxxas XRT VXL-8S (available in Blue, Orange, Green, and Black), the Traxxas XRT Ultimate (available in Green X and Blue X variants), and the Traxxas Funco Motorsports Pro Scale 8S 2WD Electric Sand Car (available in Orange, Green, Red, and Blue). Check your vehicle's model number to confirm compatibility before ordering.
• Are these shock shafts difficult to install? — Traxxas shock shafts are straightforward to install. Since these come pre-assembled with rod ends and hollow balls, installation involves simply removing your old shafts and sliding the new ones into your shock bodies, then securing them according to your vehicle's manual. No specialised tools or advanced mechanical knowledge is required, making this an ideal DIY maintenance task for intermediate RC enthusiasts.
• How often should I replace my shock shafts? — Shock shaft lifespan depends on driving intensity and maintenance. Heavy bashers and racers should inspect shafts regularly for bending or damage after crashes, whilst casual weekend drivers can expect several seasons of use. The chrome finish on these Traxxas shafts provides excellent corrosion resistance, so they'll maintain their appearance and function far longer than bare steel alternatives.
• What's the difference between GTX shocks and other Traxxas shock sizes? — Traxxas offers multiple shock lengths for different applications. The 92mm GTX size is the medium-length option, designed for vehicles requiring a specific ride height and stroke. Using the correct length ensures your suspension geometry remains true to specification, maintaining the handling balance your vehicle was engineered for. Using incorrect lengths can cause geometry changes that harm performance and potentially damage other suspension components.
• Do I need any additional parts to install these? — Since these shock shafts arrive fully assembled with rod ends and hollow balls, you don't need to purchase additional suspension components. Simply ensure your shock bodies are in good condition and ready to accept the new shafts. Check your vehicle manual for any specific installation notes or torque specifications.
• Are these suitable for beginners? — Yes, these replacement shock shafts are suitable for RC enthusiasts of all levels. Shock shaft replacement is one of the most fundamental suspension maintenance tasks and requires no specialist knowledge. The pre-assembled design means even novice builders can complete the job in minutes using only basic tools.
