Key Features
- CNC Machined Construction — Each hex is manufactured using precision CNC machining techniques, which ensures exact tolerances, perfect roundness, and flawless fitment to your Bully 2 front axle components. This level of precision engineering is essential for maintaining the handling characteristics and reliability of your scale RC machine.
- 12mm Wheel Interface — The 12mm hexadrive connection provides a universal standard interface for wheels and drivetrain components across the Bully 2 range, ensuring compatibility with a wide selection of scale wheels, beadlock hubs, and tyre setups available in the RC hobby market.
- Lightweight Design — Weighing just 0.14 ounces (4 grams) per hex, this component adds minimal unsprung weight to your front axle assembly, which helps maintain responsive handling characteristics and reduces stress on your suspension geometry during intense off-road driving.
- Dual Pack Quantity — The package includes two front axle hexes, which means you receive both left and right components needed for a complete front axle setup, or have spares ready for future rebuilds and modifications.

Technical Performance
The RC4WD Bully 2 12mm Front Axle Hex represents the pinnacle of precision engineering in the RC scale driving community. The CNC machining process employed in the manufacture of these hubs guarantees consistent diameter tolerances that ensure perfect fitment into Bully 2 Competition Front Axle assemblies (Z-A0012) and Bully 2 XVD Axle systems (Z-S0521). The 12mm hexadrive standard has become the universal connection method for modern 1/10 scale RC crawlers and bashers across the UK RC hobby scene, allowing seamless integration with countless aftermarket wheels and drivetrain components. At just 4 grams per hex, these components are engineered with weight efficiency in mind, helping to optimise the unsprung weight distribution of your front axle assembly and maintain the precise weight distribution critical to competitive scale driving. The precision-ground surfaces and exact hexadrive geometry mean that wheel changes and maintenance become straightforward processes, with no wobble, play, or fitment issues that could compromise steering response or tyre wear characteristics. Whether you're running these on a competition course, tackling challenging UK terrain, or bashing at the local RC club, the Bully 2 12mm Front Axle Hex delivers the durability and reliability required for demanding RC driving applications.

Frequently Asked Questions
- What is the 12mm hex interface and why does it matter for my RC crawler? — The 12mm hexadrive is the universal standard connection method used on modern 1/10 scale RC crawlers and scale vehicles. This interface allows you to quickly and easily change wheels, swap between different hub styles, and upgrade your drivetrain components without requiring new axles. The 12mm hex means these components work with a vast range of aftermarket wheels, beadlock hubs, and driveline parts available throughout the UK RC hobby market.
- Are these hubs compatible with my Bully 2 model? — Yes, these 12mm front axle hexes are specifically designed for the RC4WD Bully 2 platform and are confirmed compatible with the Bully 2 Competition Front Axle (Z-A0012) and Bully 2 XVD Axle (Z-S0521). If you own either of these axle systems, these hubs will fit perfectly. We recommend checking your current axle model number to confirm compatibility before ordering.
- Do I need to buy these hubs as spares or upgrades? — These hubs serve dual purposes. If you're replacing worn or damaged hubs on an existing Bully 2 setup, they're ideal OEM replacements that restore your model to original specifications. Alternatively, if you're building a new front axle assembly or upgrading your existing drivetrain, these precision CNC-machined hubs deliver the reliability and performance needed for serious RC driving. Many UK RC enthusiasts keep spares on hand to minimise downtime between bashing sessions.
- What does CNC machined mean and why is this important? — CNC (Computer Numerical Control) machining is a precision manufacturing process where computer-controlled cutting tools shape each component to exact specifications. This ensures that every hex has perfect tolerances, uniform dimensions, and flawless surfaces. For RC components, this level of precision means better fitment, smoother rotation, improved handling characteristics, and longer component lifespan compared to conventionally manufactured alternatives.
- How much do these hubs weigh and does this affect my RC car's performance? — Each hex weighs just 0.14 ounces (4 grams), which is extremely lightweight. This minimal weight helps reduce unsprung weight on your front axle, which improves suspension response, handling sharpness, and overall driving feel. For scale RC crawlers where every gram matters, lightweight components like these contribute to better traction control and more predictable steering geometry.
