Overview
The AXIAL 2.2 Internal Wheel Weight Insert 21g .75oz (4) Z-AX30546 is an essential tuning component for serious RC enthusiasts running 1/10 scale rock racers and monster trucks. These precision-engineered internal wheel weights are designed to optimise weight distribution and improve handling characteristics on vehicles equipped with 2.2-inch wheels. Whether you're a competitive racer fine-tuning your setup or an RC car UK hobbyist looking to enhance your vehicle's performance, these weight inserts offer a professional-grade solution for achieving the perfect balance in your build.
Internal wheel weights serve a critical function in RC vehicle setup, allowing drivers to adjust the centre of gravity and overall weight distribution without changing the visual appearance of their build. The 21g weight per insert gives you precise control over how your vehicle handles during acceleration, braking, and cornering. This is particularly valuable for rock racing enthusiasts who demand maximum control and predictability from their equipment. These weights are compatible with multiple Axial vehicle platforms, making them a versatile addition to any serious RC enthusiast's parts collection.
Each package contains four individual weight inserts, providing flexibility in how you distribute weight across your vehicle's wheels. The standardised 12mm hex size ensures compatibility with a wide range of Axial rock racer and monster truck platforms. Whether you're setting up a new ready to run RC vehicle or optimising an existing build, these internal wheel weights give you the fine-tuning capability that separates casual drivers from competitive racers.
Key Features
- Precise 21g Weight Rating — Each insert provides exactly 21 grams (0.75 ounces) of weight, allowing you to fine-tune your vehicle's handling and weight distribution with scientific accuracy rather than guesswork.
- Internal Mounting Design — Unlike external weights that affect the appearance of your RC car, these inserts mount inside the wheel itself, maintaining your vehicle's clean aesthetic whilst improving performance.
- 12mm Hex Compatibility — The standardised 12mm wheel hex size ensures these weights fit securely into compatible Axial wheels without requiring modification or adapters.
- Set of Four Inserts — Each package includes four individual weight inserts, giving you the flexibility to distribute weight exactly where your specific setup needs it most.
- Engineered by Axial — As an official Axial replacement and optional part, these weights are manufactured to the same high standards as the vehicles they're designed to enhance.
- Multiple Vehicle Compatibility — These weights are proven compatible with several Axial rock racer and monster truck platforms, including the RR10 Bomber, Wraith Spawn models, and other 1/10 scale vehicles with 2.2-inch wheels.
Technical Performance
These internal wheel weight inserts represent the kind of precision engineering that Axial vehicles are known for. At 21 grams per insert, they provide meaningful weight adjustment without excess that would negatively impact performance. The internal mounting system means the weight is distributed directly within the wheel structure itself, which is superior to external mounting methods because it maintains a lower centre of gravity and preserves the sleek appearance of your RC vehicle. The 2.2-inch wheel diameter specification indicates these are designed for 1/10 scale platform vehicles, which are the most popular category in the ready to run RC car UK market. The 12mm hex size is the industry standard for Axial 1/10 scale vehicles and ensures secure, wobble-free mounting. These weights work equally well at the front and rear of your vehicle, giving you complete flexibility in your setup approach. Serious rock racers and monster truck enthusiasts understand that weight distribution directly affects suspension geometry, traction, and overall handling response. By allowing you to fine-tune weight placement, these inserts enable you to dial in your vehicle's behaviour to match your driving style, terrain conditions, and track layout. Whether you're running on rocky terrain, sand, or mixed surfaces, the ability to adjust your vehicle's weight distribution can be the difference between a frustrating session and a competitive advantage.
