Key Features

• Extreme Heavy Duty Driveshafts with Ten Curvilinear Splines — The driveshafts feature six millimetre stub axles, large-diameter half shafts, and massive universal joints that are significantly larger in diameter than standard components, providing superior strength and durability for brushless power systems. The innovative ten curvilinear spline design (compared to the stock four square splines) means each individual spline carries less load, resulting in dramatically greater durability and extended shaft life. The large-diameter design resists twisting so your RC truck puts full power into the tyres in maximum-grip conditions, no matter how hard you apply the throttle. The curvilinear splines and precise fit assure smooth telescoping action under power, delivering superior suspension articulation for excellent shock absorption and tighter turning.
• 20% Larger Sealed Outer Bearings — The kit includes rubber-sealed bearings that are twenty percent larger than stock parts, delivering greater strength, longer operational life, and low-drag performance that keeps your truck responsive and reliable during extended bashings.
• Heavy Duty Caster Blocks and Steering Blocks with 50% More Composite Material — By weight, the Extreme Heavy Duty caster and steering blocks are moulded with fifty percent more composite material than stock versions, delivering incredible strength and durability where it matters most in the suspension geometry.
• Rear Hub Carriers with 200% More Material — The rear carriers use two hundred percent more material than stock, creating an exceptionally robust rear suspension that can handle extreme punishment from aggressive driving and high-powered brushless motors.
• One-Piece Heavy Duty Camber and Toe Links — These revised components work specifically with the Extreme Heavy Duty driveshafts, with camber link mounting points raised for proper driveshaft clearance, ensuring flawless integration and optimal suspension geometry.
• Heavy Duty Front and Rear Suspension Arms — Moulded from Traxxas's toughest composite material, these suspension arms provide just the right amount of flex to resist breaking, standing up to even the most punishing drivers for non-stop bashing without compromising rigidity.
• Steel Rear Wheel Hexes — Heavy-duty steel wheel hexes replace standard parts, providing superior strength and reliability where the wheels connect to the driveline, critical for withstanding aggressive acceleration and high-speed impacts.
• Complete Hardware Package Included — Everything you need to install the kit is included; hex hardware is pre-selected and ready to go, eliminating any guesswork and ensuring proper fitment.
• Compatible with Existing Aluminium Accessories — The upgrade kit works seamlessly with your existing aluminium upgrades and accessories, allowing you to build your perfect setup incrementally or all at once.
• Easy Installation Without Chassis Modification — The kit installs without any modification to your Rustler 2WD or Stampede 2WD, meaning you maintain the integrity of your chassis whilst gaining extreme durability in the areas that matter most.
• Available in Multiple Vibrant Colours — Beyond the standard black, you can choose from five custom colours including this striking green, allowing you to personalise your RC truck's appearance whilst upgrading its durability.

Technical Performance

The Traxxas Extreme Heavy Duty Outer Driveline & Suspension Upgrade Kit represents a quantum leap forward in durability for 2WD stadium trucks and short course vehicles. Every component has been engineered specifically to work together as a complete, integrated package that transforms your RC car's capability. The signature innovation is the new driveshaft design featuring six millimetre stub axles and ten curvilinear splines—a design philosophy that distributes loads more evenly across the engagement surfaces, dramatically reducing stress on any single spline and extending service life significantly. These larger-diameter half shafts with massive universal joints resist twisting under power delivery, ensuring that 100% of your brushless motor's output translates directly to wheel grip and acceleration rather than being lost to component flex. The combination of oversized bearings (twenty percent larger than stock), reinforced composite structures (fifty percent more material in front blocks, two hundred percent more in rear carriers), and heavy-duty suspension arms creates a chassis that can absorb punishment from high-speed impacts, jumps, and aggressive driving whilst maintaining precise handling characteristics. The revised shock towers and camber link mounting points ensure perfect clearance and geometry with the new driveshaft system, whilst the steel rear wheel hexes provide the kind of uncompromising durability needed when running brushless motors. Installation takes approximately thirty minutes and requires no modifications to your existing chassis, making this upgrade accessible to builders of all experience levels. The complete package of driveline and suspension components is engineered to work as one cohesive system, delivering superior suspension articulation, exceptional shock absorption, and the confidence to push your 2WD Rustler or Stampede to its absolute limits.

Frequently Asked Questions

• Which Traxxas 2WD models does the Extreme Heavy Duty Upgrade Kit fit? — This kit is specifically designed for the Rustler 2WD and Stampede 2WD. It will not fit the Stampede 4WD or other 4WD models; note that the separate Extreme Heavy Duty 4X4 Upgrade Kit is available for 4WD vehicles such as the Hoss 4X4, Slash 4X4, and Rustler 4X4. The kit installs without any chassis modification on compatible 2WD models.
• How long does it take to install the Extreme Heavy Duty Upgrade Kit? — Installation typically takes approximately thirty minutes at the workbench. No modifications to your existing chassis are required; the kit is designed to bolt directly onto your Rustler 2WD or Stampede 2WD, making it accessible even to builders with moderate experience.
• What makes the Extreme Heavy Duty driveshaft design so much better than stock? — The revolutionary ten curvilinear spline design (versus stock four square splines) distributes power loads much more evenly, meaning each spline carries less stress and the shafts last significantly longer. The larger-diameter design resists twisting so your brushless motor's full power goes directly to the tyres. The curvilinear geometry and precise engineering also ensure smooth, reliable telescoping action under power, delivering superior suspension articulation and shock absorption for a more capable and durable truck.
• Is the Extreme Heavy Duty kit compatible with existing aftermarket parts I already own? — Yes, the upgrade kit works seamlessly with existing aluminium accessories and upgrades. However, it is not compatible with aluminium caster blocks, steering blocks, or axle carriers, so ensure you're using the heavy duty composite versions from this kit or other compatible Traxxas heavy duty options.
• Why are the sealed outer bearings twenty percent larger? — Larger driveshafts require larger bearings to handle the increased loads and stresses they'll experience, particularly with brushless motors. These oversized, rubber-sealed bearings deliver greater overall strength, extended operational life, and low-drag performance that keeps your truck running smoothly and responsively throughout extended bashings.
• Is this upgrade suitable for brushless motors? — Yes, the Extreme Heavy Duty kit is specifically engineered for brushless power systems. The reinforced driveshafts, upgraded bearings, and heavy duty suspension components are all designed to handle the power and torque that modern brushless motors deliver, making this the ideal upgrade for owners running brushless ESCs and motors on their 2WD trucks.
• Can I mix and match parts from this kit with stock components? — Whilst you can replace individual components, the kit is engineered to work as a complete, integrated package for optimal performance. All the components have been designed to work together seamlessly, so installing the complete kit ensures you get the full durability and performance benefits.
• Does this kit change the handling or driving characteristics of my Rustler 2WD or Stampede 2WD? — The kit is designed to maintain your truck's handling characteristics whilst dramatically improving durability. The revised shock towers work with the Extreme Heavy Duty driveshafts to maintain proper geometry, and the heavier-duty suspension components provide better suspension articulation and shock absorption, potentially offering slightly improved control during aggressive driving.
