Key Features

• Extreme Heavy Duty Driveshafts with 10 Curvilinear Splines — The driveshafts feature a revolutionary 10 curvilinear spline design compared to just four square splines on stock parts, which means each individual spline carries significantly less load, resulting in dramatically greater durability and longer shaft life even under extreme brushless power.
• Large-Diameter Half Shafts with 6mm Stub Axles — The larger diameter design actively resists twisting, ensuring your truck puts full power directly into the tyres in maximum-grip conditions no matter how hard you apply the throttle, delivering superior traction when it matters most.
• Beefed-Up U-Joints on Driveshafts — Heavy-duty universal joints are engineered specifically to handle brushless power systems with ease, providing the strength needed for high-performance bashing without compromising reliability.
• 20% Larger Sealed Outer Bearings — The rubber-sealed bearings are considerably larger than stock parts for greater strength, longer operational life, and low-drag operation that keeps your truck running smoothly even under demanding conditions.
• 50% More Composite Material in Caster & Steering Blocks — By weight, the front caster and steering blocks are moulded with 50% additional composite material compared to stock parts, providing extraordinary durability and impact resistance that withstands even the most punishing drivers.
• 200% More Material in Rear Hub Carriers — The rear axle carriers feature 200% more material than standard parts, making them incredibly tough where it counts most, protecting your truck's rear suspension geometry under aggressive driving.
• 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 whilst standing up to even the most brutal bashing for non-stop driving action.
• One-Piece Heavy Duty Camber and Toe Links — These integrated links maintain precise suspension geometry whilst offering superior strength and reliability compared to separate components, ensuring consistent handling throughout your driving session.
• Steel Rear Wheel Hexes — Heavy-duty steel hexes provide maximum durability and secure wheel mounting, preventing stripping even when pushing your truck to its absolute limits with brushless power.
• Superior Suspension Articulation — The telescoping driveshaft design provides excellent suspension travel and shock absorption, allowing your truck to maintain traction over rough terrain and absorb impacts more effectively than standard setups.
• Compatible with Existing Aluminium Accessories — The upgrade kit works seamlessly with your existing aluminium accessories, giving you flexibility to customise your truck whilst benefiting from the extreme durability of this package.
• Easy Installation with Hex Hardware Included — Everything you need comes in the box, including all necessary hex hardware, and the kit installs without any modifications required to your truck, getting you back to bashing in roughly half an hour.

Technical Performance

The Extreme Heavy Duty Outer Driveline & Suspension Upgrade Kit represents a quantum leap in durability engineering for 2WD brushless RC trucks. Every component in this package has been specifically designed to withstand the extreme stresses of brushless power systems whilst maintaining exceptional performance on the track or at the bash spot. The driveshaft engineering is particularly impressive — the shift from four square splines to ten curvilinear splines fundamentally changes how load is distributed through the drivetrain, with each spline carrying less stress and the curved profile ensuring smooth, consistent engagement even during hard acceleration or aggressive turning. The large-diameter half shafts resist twisting under maximum throttle application, ensuring power is transferred directly to the ground with minimal loss. The 20% larger sealed bearings are rubber-sealed for protection against dirt and moisture whilst providing ultra-low drag operation, crucial for maintaining top speed and efficiency. The suspension components feature revolutionary increases in material density — the front blocks gain 50% additional composite strength whilst the rear carriers nearly triple their material content. This isn't simply aesthetic beefing; it's engineering-led durability. The revised shock tower mounting points have been repositioned to accommodate the larger driveshafts whilst maintaining perfect clearance during full suspension articulation. The kit's one-piece camber and toe links simplify assembly whilst improving geometry consistency. The heavy-duty suspension arms are moulded from Traxxas's toughest composite and specifically tuned to provide flex resistance without becoming brittle, a critical balance for trucks running brushless power. Installation is straightforward with precise fitment across all compatible models — Rustler 2WD, Stampede 2WD, and BIGFOOT — requiring no chassis modifications whatsoever.

Frequently Asked Questions

• What vehicles is the Traxxas Extreme Heavy Duty Upgrade Kit compatible with? — The kit is specifically designed for the Traxxas Rustler 2WD, Stampede 2WD, and BIGFOOT, and installs without any modifications required. The Stampede 4X4 and Rustler 4X4 models are not compatible with this 2WD-specific kit, and the Extreme Heavy Duty components are not compatible with aftermarket aluminium caster blocks, steering blocks, or axle carriers.
• Is this upgrade kit suitable for brushless RC trucks? — Yes, the Extreme Heavy Duty kit is specifically engineered for brushless power systems and is recommended for trucks running brushless motors and ESCs. The beefed-up driveshafts, larger bearings, and reinforced suspension components are all designed to handle the higher torque and power delivery of brushless motors.
• How much harder is the Extreme Heavy Duty kit compared to stock parts? — The kit features 50% more composite material in the front caster and steering blocks by weight, whilst the rear hub carriers use 200% more material than standard parts. The driveshafts are noticeably larger in diameter with beefed-up universal joints, and the sealed outer bearings are 20% larger than stock alternatives.
• Will this kit improve my truck's performance as well as durability? — The Extreme Heavy Duty upgrade primarily focuses on durability and reliability under extreme conditions, but the larger driveshafts and improved bearing design do provide benefits including smoother operation, superior suspension articulation, and better shock absorption over rough terrain. The one-piece camber and toe links also contribute to more consistent handling.
• How long does installation take? — Installation takes approximately 30 minutes for an experienced builder with basic tools. The kit includes all necessary hardware and comes with clear instructions. No chassis modifications are required, making the installation straightforward on compatible models.
• Can I mix and match Extreme Heavy Duty parts with my stock suspension? — Whilst the kit is designed to work as a complete package for optimal durability and performance, individual moulded parts including the caster blocks, steering blocks, and hub carriers are available separately should you need to replace individual components or mix colours.
• What is the difference between the stock driveshaft splines and the Extreme Heavy Duty design? — Stock driveshafts engage via four square splines, whilst the Extreme Heavy Duty driveshafts use ten curvilinear splines. The greater number of splines means each individual spline carries significantly less load, resulting in greater durability and longer shaft life. The curvilinear design also ensures smooth telescoping action under power.
• Is this the same as the 4X4 Extreme Heavy Duty kit? — No, this is the 2WD version designed specifically for the Rustler 2WD, Stampede 2WD, and BIGFOOT. The 4X4 Extreme Heavy Duty kit is a separate product designed for the Hoss 4X4, Slash 4X4, and Rustler 4X4, with different geometries and shock tower designs.
• What colours are available for the Extreme Heavy Duty upgrade kit? — The kit is available in blue, black, red, green, and orange, allowing you to match your truck's colour scheme or create a custom two-tone look with existing body colours.
