Whether you are upgrading from factory standard components or replacing a worn driveshaft on your existing RC model truck, this steel constant-velocity driveshaft is the go-to choice for UK RC car enthusiasts who refuse to compromise on performance. The TRX8950A is ideal for basher enthusiasts, competitive racers, and anyone running high-torque brushless motors who needs a driveshaft that can handle the punishment of serious RC driving. When you choose a Traxxas steel CV driveshaft, you are investing in proven engineering that has been tested and refined through years of real-world RC competition and high-performance applications.

This shaft-only component (compatible exclusively with the #8951 drive cup) allows customisation of your drivetrain setup whilst maintaining the legendary quality and performance that has made Traxxas the trusted name in RC vehicles across the UK and worldwide. The 89.5mm length makes this the perfect replacement for Traxxas Maxx models, delivering seamless integration with your existing suspension and chassis geometry.

Key Features

• Steel Constant-Velocity Design — The CV joint technology ensures smooth, efficient power transfer at all suspension angles and articulation points, meaning your motor's power reaches the wheels without hesitation or vibration, even during extreme suspension compression and extension.
• Exceptional Torque Handling — Engineered specifically for high-power brushless applications, the steel construction and precision engineering allow this driveshaft to handle the enormous torque loads generated by modern brushless motor systems without bending, cracking or failing under sustained high-power operation.
• Bearing-Secured Drive Pins (Axle Side) — On the axle side, robust bearings secure the drive pins in place, preventing them from backing out during aggressive driving, collisions, or intense acceleration and braking cycles that would stress lesser components.
• Large-Bore Press-Fit Drive Pins (Differential Side) — Heavy-duty, large-bore drive pins are precision press-fit on the differential side and slot into the Traxxas heavy-duty steel drive cups, creating a rock-solid connection that transmits maximum torque with zero play or slippage.
• Rubber-Sealed Bearings — The included bearings feature rubber seals to keep out dirt, mud, water, and debris that would otherwise contaminate the joint and cause premature wear, ensuring longevity even in harsh RC driving conditions.
• Black-Oxide Rust Prevention Coating — A durable black-oxide coating has been applied to the drive gear, helping prevent rust and corrosion from moisture and salt exposure, which is especially valuable for UK RC drivers who may encounter wet or coastal conditions.
• Splined Telescoping Design — Traxxas' unique splined telescoping construction delivers full-range articulation without any suspension travel limitations, meaning your Maxx can compress and extend its suspension fully whilst maintaining perfect CV joint operation and power delivery.
• Compatibility with V.1 Narrow Maxx Suspension — This driveshaft is specifically designed for the V.1 narrow Maxx suspension geometry, ensuring perfect fitment and clearance without modification or adjustment.

Technical Performance

The Traxxas TRX8950A driveshaft represents the pinnacle of RC transmission engineering, combining premium materials, precision manufacturing, and intelligent design to deliver uncompromising performance in the most demanding applications. The steel construction throughout the shaft and CV joint assembly provides exceptional rigidity and strength compared to aluminium or composite alternatives, making it the professional choice for high-torque brushless RC cars and trucks.

At 89.5mm in length, this driveshaft is precisely engineered to work with the Traxxas Maxx chassis geometry, maintaining optimal suspension kinematics and ensuring that your vehicle's ground clearance, approach angles, and departure angles remain unchanged. The constant-velocity joint technology ensures that power delivery remains smooth and linear regardless of suspension position, eliminating the dead spots and power loss that can occur with inferior joint designs. The bearing-secured drive pins on the axle side work in concert with the large-bore press-fit pins on the differential side, creating a multi-point connection that distributes loads evenly and prevents the single-point failures that plague budget driveshaft designs. The rubber-sealed bearings protect against contamination whilst allowing smooth rotation, and the black-oxide coating provides lasting corrosion resistance. This is genuine Traxxas engineering — built to handle the sustained abuse of high-speed bashers, competitive racers, and serious hobbyists alike.

Frequently Asked Questions

• What models does the Traxxas TRX8950A driveshaft fit? — This shaft is designed for the Traxxas Maxx with V.1 narrow suspension geometry. It will not fit models with the WideMaxx suspension installed, as the suspension geometry and driveshaft length requirements differ. Always verify your Maxx variant before ordering.
• Why is this shaft-only and not a complete driveshaft set? — The TRX8950A is sold as a shaft-only component to allow RC enthusiasts to upgrade individual driveshafts without purchasing a complete set, reducing cost for targeted repairs or improvements. You will need the compatible #8951 drive cup to complete your driveshaft assembly, but this gives you flexibility in your upgrade path.
• Is the steel constant-velocity driveshaft better than other options? — Yes, the steel CV design offers superior torque handling and power transfer efficiency compared to composite or standard steel designs. The constant-velocity joint ensures smooth power delivery at all suspension angles, whilst the steel construction provides exceptional durability for high-power brushless applications. This is the premium choice for serious RC driving.
• Will this driveshaft work with my high-torque brushless motor? — Absolutely. The TRX8950A is specifically engineered for high-power brushless applications and features reinforced drive pins, bearing-secured joints, and premium materials throughout to handle the enormous torque loads generated by modern brushless motors. This is exactly what you need for maximum power transfer.
• How does the rubber-sealed bearing design help with durability? — The rubber seals keep dirt, mud, water, and debris out of the bearing races, preventing contamination that would cause friction, wear, and eventual failure. This is especially important for RC bashers and off-road vehicles exposed to harsh conditions, and it means your driveshaft will maintain smooth operation and last significantly longer than unsealed alternatives.
• What does the black-oxide coating do? — The black-oxide coating is a rust-prevention treatment applied to the drive gear components. It creates a barrier against moisture and corrosion, helping your driveshaft resist rust formation from water exposure, salt spray, and humid conditions — a particularly important feature for UK RC drivers who may encounter wet weather and coastal environments.
• Can I use this shaft with a different drive cup? — No, this shaft is designed exclusively for use with the Traxxas #8951 drive cup. Using it with other drive cup designs may result in poor fitment, power loss, or premature failure. Always use the correct compatible components.
• What wheel hubs and nuts do I need? — This driveshaft requires Traxxas 8654-series 17mm splined wheel hubs and Traxxas 7758-series 17mm wheel nuts for proper wheel installation and secure fastening. These specifications must be followed to ensure correct operation and safety.
