Overview
The ARRMA CVD Slider Set for the 4x4 Mega BLX is a premium transmission upgrade designed to deliver super-smooth power transfer from your differential directly to your wheels. This is an essential replacement or upgrade component for serious RC enthusiasts running ARRMA's popular Mega BLX models, and it represents the kind of quality engineering that separates weekend bashers from dedicated hobbyists. Whether you're upgrading a well-used RC car UK model or building out a competition-ready platform, this CVD slider drive shaft set offers the durability and precision you need for consistent performance.
As one of the most trusted names in RC vehicles, ARRMA has engineered this driveshaft assembly to handle the demands of high-performance 4WD RC trucks and cars. The CVD (Constant Velocity) slider design is particularly valued in the RC community because it maintains consistent power delivery through varied terrain and driving angles—something that makes all the difference when you're tackling technical courses or pushing your brushless RC vehicle to its limits. This is genuine, authorised ARRMA component designed specifically for models in the Mega BLX family, ensuring perfect fitment and compatibility with your existing setup.
If you own an ARRMA 4x4 Mega BLX-based ready to run RC car UK model, or you're building a custom setup from these proven components, the CVD Slider Set is a wise investment in reliability and performance. The assembly comes fully constructed and ready for installation, meaning you can have your vehicle running at peak performance in minutes rather than hours.
Key Features
- Tough, Impact-Absorbing Slider Drive Shafts — The slider design incorporates flexibility and shock absorption to protect against impact damage during aggressive driving, reducing the chance of catastrophic failure when you hit rough terrain or obstacles at speed.
- Super-Strong Machined Steel Differential Outdrives and Wheel Axles — These components are precision-machined from high-quality steel, providing the strength needed to handle the torque output of a brushless motor without flex or deformation, ensuring reliable power transmission in all conditions.
- Precision Manufactured for Excellent Fit and Finish — Every component is engineered to tight tolerances, meaning smooth installation, minimal play, and consistent performance across multiple driving sessions and different track conditions.
- Supplied Fully Assembled and Ready for Installation — There is no need to spend time assembling driveshafts; these arrive complete and ready to bolt into your vehicle, saving you valuable setup time and reducing the risk of assembly errors.
- Universal Front or Rear Fitment — The set can be installed on either the front or rear axles of your vehicle, providing flexibility in your build and allowing you to upgrade one or both ends of your RC car depending on your driving style and wear patterns.
Technical Performance
The CVD Slider Set represents cutting-edge drivetrain engineering for 1/10-scale 4WD RC vehicles. The constant velocity design means power is delivered smoothly regardless of the angle at which the driveshaft is operating, which is critical when cornering hard or climbing over uneven terrain. The machined steel outdrives and wheel axles are manufactured to exacting standards, ensuring that the forces transferred from your brushless motor through the differential are handled without slipping, flexing, or wearing prematurely. The slider mechanism absorbs impacts and vibration, protecting the rest of your drivetrain from shock loads that could otherwise damage more expensive components like your motor or ESC. This is the kind of quality componentry that distinguishes genuine ARRMA replacement parts from budget alternatives—the engineering is designed around the realities of high-performance RC driving, where consistency and durability are paramount. The assembled construction means every internal component has been properly fitted and tested at the factory, so you get superior precision compared to parts assembled in the field.

Frequently Asked Questions
- Which ARRMA models does this CVD Slider Set fit? — This set is compatible with the full range of ARRMA 4x4 Mega BLX models, including the Big Rock 3S, Granite 3S and 4X4, Senton 3S and 4X4, Gorgon 2WD, and Vorteks 3S 4X4 variants. It can be fitted to either the front or rear of your vehicle.
- Do I need to replace both front and rear driveshafts at the same time? — This set includes two assembled driveshafts, which is enough for one complete axle (either front or rear). If you want to upgrade both ends of your vehicle, you will need two sets. Many users choose to replace whichever end experiences the most wear first, then upgrade the other end later.
- Is this suitable for beginners? — While this is a replacement part rather than a complete vehicle, the installation is straightforward enough for anyone with basic RC maintenance experience. The driveshafts arrive fully assembled, so there is no complex building required—simply remove the old driveshafts and slide in the new ones. If you are new to RC car maintenance generally, our team at RC Model Shop can provide guidance on installation.
- What makes this CVD slider design better than standard driveshafts? — The slider mechanism allows for constant velocity power delivery at any operating angle, which means smoother acceleration through corners and over uneven ground. The impact-absorbing design also protects your drivetrain from shock loads that could otherwise cause premature wear or failure. This is particularly valuable if you run a high-powered brushless motor.
- How often do I need to replace these driveshafts? — Driveshaft lifespan depends on driving intensity and conditions. Regular inspection is recommended, and replacement should be considered if you notice any bending, play, or unusual noises. Many competitive RC drivers replace driveshafts as part of seasonal maintenance.
- Will these work with my current setup? — These are genuine ARRMA parts designed specifically for the 4x4 Mega BLX family. If you own an ARRMA model from this range, compatibility is guaranteed. Check the fitment list on the product page to confirm your specific model is listed.
