Key Features

• Genuine Traxxas OEM Component — These shock shafts are manufactured by Traxxas to the exact same specifications as the original components fitted to your UDR, ensuring perfect fitment, durability, and performance consistency that aftermarket alternatives cannot guarantee.
• 81mm Length (GTR Specification) — The 81mm length is specifically engineered for the GTR shock configuration used on the rear suspension of the UDR Unlimited Desert Racer, providing the correct geometry and travel characteristics that keep your truck handling predictably.
• Rear Suspension Application — These shafts are designed specifically for rear shock installation on the UDR platform, meaning they incorporate the precise engineering needed for the rear suspension geometry of this vehicle.
• Two-Piece Pack — You receive a pair of shock shafts in this single purchase, which is practical since both rear shocks can be replaced simultaneously, ensuring matched performance across the rear suspension and eliminating any handling imbalance that mismatched components might introduce.
• Compatible with Multiple UDR Variants — These shock shafts work with both the TRX85086-4-FOX1 UDR with Fox Racing suspension and the TRX85086-4-RGD1 UDR with Rigid Industries suspension, making them a versatile spare part for any UDR owner in the UK.
• Direct Replacement Part — Rather than experimenting with non-genuine alternatives, these authentic Traxxas components slot directly into your existing shock assemblies, saving you time and ensuring your UDR performs exactly as Traxxas engineered it.

Technical Performance

The shock shaft is a critical component within your RC truck's damping system, and these Traxxas-engineered parts are constructed to withstand the demanding forces generated during aggressive driving, competitive racing, and rough terrain bashing. The 81mm length is precisely calculated to work in harmony with the GTR shock body, springs, and fluid specification used in the UDR platform. Traxxas manufactures these shafts from high-quality materials selected for their durability, corrosion resistance, and ability to maintain precise tolerances even after extended use. The shaft must operate smoothly within the shock body whilst maintaining a perfect seal, and Traxxas engineering ensures that these components continue to provide consistent damping performance race after race. When shock shafts wear or become bent, the damping performance becomes unpredictable, leading to poor handling characteristics and uneven suspension response across the vehicle. By replacing worn shafts with genuine Traxxas parts, you restore the precision suspension geometry that makes the UDR such an effective short course truck platform. The chrome-plated finish on quality shock shafts provides additional corrosion resistance, which is particularly important in the UK climate where moisture exposure during outdoor RC sessions can lead to rust formation on lesser-quality components. Whether you're competing in time trials, racing against friends, or simply enjoying high-speed runs across fields and tracks, maintaining your suspension with genuine parts ensures your UDR remains a competitive and reliable performer.

Frequently Asked Questions

• Which Traxxas UDR models are compatible with these TRX8464 shock shafts? — The TRX8464 shock shafts fit both the TRX85086-4-FOX1 Traxxas UDR Unlimited Desert Racer Pro-Scale 4WD RTR Short Course Truck with Fox Racing suspension and the TRX85086-4-RGD1 UDR with Rigid Industries suspension. Both variants use the same 81mm GTR rear shock configuration, so these parts are compatible with either model available in the UK market.
• Why would I need to replace my shock shafts? — Shock shafts can become bent through impacts with obstacles, worn through extended use as the internal seals degrade, or damaged during crashes and rollovers. When shafts are bent or worn, the shock no longer produces consistent damping, which leads to unpredictable handling. Replacing them with genuine Traxxas parts restores the precision performance your UDR deserves.
• Are these genuine Traxxas parts or aftermarket alternatives? — These are 100% genuine Traxxas OEM (original equipment manufacturer) parts, manufactured to the exact specifications of the components Traxxas installs in new vehicles. This ensures perfect fitment, optimal performance, and the durability standards Traxxas is known for throughout the RC hobby community in the UK and worldwide.
• How often should I replace shock shafts on my RC truck? — Shock shaft replacement depends entirely on your driving style and usage intensity. Competitive racers might replace them seasonally, whilst casual bashers might get several seasons of use. Inspect them regularly for bending or visible damage, and replace them whenever you notice handling inconsistencies or visible shaft damage.
• What is the difference between front and rear shock shafts on the UDR? — The UDR uses different shock shafts for front and rear suspension, and they cannot be interchanged. The TRX8464 is specifically designed for rear installation on the UDR platform. Always check your vehicle documentation or contact our RC Model Shop team to ensure you order the correct shafts for your application.
• Can I use these shafts on other Traxxas models? — No, these shafts are specifically engineered for the UDR platform and will not fit other Traxxas models, even if they appear similar. Using non-compatible components can damage your vehicle and create unsafe handling characteristics. Always source parts specifically designed for your model.
