Whether you're upgrading an existing X-Maxx or XRT, or building a new RC truck from the ground up, these drivecups provide the foundation for reliability and peace of mind during high-speed runs and extreme driving conditions.

Key Features

• HD Steel Construction with Hardened Treatment — The drive cups are manufactured from premium 45# steel material that has undergone hardened treatment, creating an incredibly tough and wear-resistant component that can withstand the punishing forces of 8S LiPo powered runs without deformation or premature failure.
• Increased Diameter Design — Vitavon has increased the diameter of both the shaft and drive cup compared to standard equipment, which distributes load more effectively across a larger surface area, reducing stress concentration and extending the lifespan of these critical components significantly.
• High-Quality Aluminium Stub Axles — The stub axles are crafted from high-quality aluminium #7075, a premium alloy known for its exceptional strength-to-weight ratio, ensuring the assembly remains rigid whilst keeping overall weight minimal for optimal vehicle dynamics.
• 4mm Pin Fixing System — The shafts feature 4mm pin fixing specifically engineered for X-Maxx 8S operation, providing absolutely secure retention during acceleration, braking, and cornering to prevent any slip or unwanted movement under extreme driving conditions.
• 4-Slot Configuration for Extended Use — The 4-slot design means each component can be cycled through four times before replacement is required, effectively doubling the lifespan compared to standard 2-slot systems and representing exceptional value for serious RC enthusiasts.
• Compatible with X-Maxx and XRT Platforms — Whilst primarily designed for the Traxxas X-Maxx 1/5 scale vehicle, these drive cups also fit the Traxxas Sand Car rear applications, offering versatility across multiple high-performance platforms within the Traxxas ecosystem.
• CVD Shaft Technology — The constant velocity drive shafts maintain consistent power delivery throughout the full range of suspension articulation and steering angles, ensuring smooth acceleration and braking performance without binding or vibration.

Technical Performance

The engineering excellence embedded in this Vitavon drive cup set focuses on material science and manufacturing precision. The 45# steel used for the drive cups undergoes hardened treatment, creating a surface that resists wear, abrasion, and deformation under the enormous forces generated by high-performance brushless RC vehicles running on 8S LiPo batteries. The increased diameter design compared to factory equipment spreads loads more effectively, reducing peak stress concentrations and extending service life substantially. The aluminium #7075 stub axles provide the perfect balance between strength and weight, maintaining the rigidity necessary for precise control whilst avoiding unnecessary mass that could affect handling characteristics. The 4mm pin fixing system is engineered specifically for X-Maxx 8S applications, which demands absolute security in the driveline given the extreme torque and acceleration forces involved. This is not a generic solution — it is precisely tailored engineering for one of the most demanding 1/5 scale platforms available. The CVD shaft technology ensures that power is delivered smoothly throughout the vehicle's full range of motion, eliminating the binding and vibration that can occur with inferior constant velocity joints. For UK RC car enthusiasts and competitive racers alike, this level of engineering translates directly to reliability, improved durability, and reduced maintenance intervals during extended racing campaigns.

Frequently Asked Questions

• Are these Vitavon drive cups a worthwhile upgrade for my X-Maxx 8S? — Absolutely. The original Traxxas equipment is adequate for casual use, but if you're running an 8S LiPo powered X-Maxx with any regularity, the factory driveline components experience significant stress and wear. Upgrading to Vitavon's HD steel construction with hardened treatment provides substantially improved durability, reduced wear rates, and extended service intervals. Many UK RC enthusiasts find that upgrading the driveline is one of the first and best modifications they make to their high-performance vehicles, as it prevents catastrophic failures that can damage other components and sideline your vehicle unexpectedly.
• What does the 4-slot configuration actually mean? — The drive cups feature four separate engagement points or slots rather than the standard two. This means each cup can be used and rotated through multiple positions before it becomes too worn for reliable use, effectively doubling or tripling the functional lifespan of the component compared to a standard 2-slot design. This represents exceptional value for money and reduces the frequency with which you need to purchase replacement parts.
• Will these fit my Traxxas Sand Car? — Yes, these drive cups are confirmed compatible with Traxxas Sand Car rear applications in addition to the X-Maxx platform. However, you should verify fitment with a specialist UK RC retailer if your specific Sand Car variant uses different driveline geometry, as certain model variations may have slight dimensional differences.
• What makes 45# steel superior to the standard material? — 45# steel (AISI 1045) is a medium-carbon steel chosen specifically for its excellent balance of toughness and wear resistance. When hardened through proper heat treatment, this material develops a surface hardness that resists abrasion and deformation under the extreme forces generated by acceleration, braking, and cornering. The hardening process creates a dense, tough crystalline structure that simply cannot be matched by unhardened or lower-grade steel, which is why serious RC competitors standardly upgrade to hardened steel driveline components.
• Is professional installation required? — No, any RC hobbyist with basic mechanical aptitude and standard RC tools can install these components. However, given that the driveline is mission-critical for vehicle safety and performance, it is absolutely worth taking time to ensure proper assembly, correct torque specifications, and secure pin retention. If you are not confident in your mechanical skills, we recommend consulting an experienced RC mechanic or visiting a specialist UK RC hobby shop for professional installation.
• How do CVD shafts differ from solid axles? — CVD (constant velocity) shafts maintain consistent power delivery throughout their operating range, whether the suspension is compressed, extended, or the wheels are turned at extreme steering angles. Solid axles cannot accommodate these varying angles without binding or creating vibration. For a vehicle like the X-Maxx with significant suspension articulation and steering range, CVD shafts are essential for smooth, reliable performance and are superior in every measurable way.
