INJORA 15mm Black Brass Wheels Hex Hub Extenders for SCX10 & SCX10 II
Best for: SCX10 and SCX10 II owners needing a noticeable stance increase. The 15mm offset adds width to improve stability on challenging terrain, aiding cornering and wheel protection. The heavy brass construction offers durability but adds weight, which can affect suspension response. Choose this if you want a pronounced widen and primarily run on rugged, off-road trails.
INJORA 12mm Black Brass Wheels Hex Hub Extenders for Axial SCX10 & SCX10 II
Best for: Axial SCX10 models seeking a modest widen for enhanced stability without overloading the drivetrain. The 12mm offset is a balanced choice for trail runs, rock crawling, and general scaling. Limitation: brass parts add weight, which can influence steering response and battery life in tight climbs. Best for users who prefer a slimmer widen with reliable durability.
Metal 12mm Hex Wheel Hubs with 7mm Thick Drive Adapters
Best for: Traxxas 1/10 4WD (Rustler, Slash, Stampede) enthusiasts wanting robust, solid hubs. The 7mm thick adapters provide a strong interface and reduce flex under load. Better for users prioritizing durability over ultra-lightweight builds. Caution: check fitment against specific Traxxas models as variations exist across generations.
4Pcs Vgoohobby 12mm Turn 17mm Wheel Hub Extenders
Best for: 1/10 RC buggies, monster trucks, and off-road models where versatility matters. The 30mm offset range supports a broader stance, improving stability on loose terrain. Choose this if you want a flexible widener that can be tuned across multiple chassis types. Limitation: longer offset may affect wheel track alignment on narrow bodies.
ShareGoo Aluminum 12mm to 17mm Wheel Extension
Best for: Multi-platform builds needing an adjustable widening path from 12mm to 17mm. Aluminum construction provides a good strength-to-weight balance for performance-focused setups. Better for mixed rigs that switch between Axial, Tamiya, and Traxxas parts. Caution: verify compatibility with tire bead seats and wheel offsets to avoid interference with suspension arms.
Buying Guide
What should you consider when choosing a 12mm wheel widener?
- Compatibility: Confirm hub diameter, thread type, and the vehicle’s axle design to ensure a proper fit.
- Offset range: Decide how wide you want the stance to be. Larger offsets improve stability but can alter steering geometry.
- Material and weight: Brass and aluminum offer durability, with brass adding weight and aluminum reducing unsprung mass.
- Durability vs. weight: Heavier hubs resist impacts but may affect efficiency; lighter hubs improve agility but may wear faster.
- Installation: Look for easy, clear mounting methods and compatibility with existing lock nuts and nuts.
- Tire fit: Ensure tires clear wheel wells and suspension components at full articulation.
Performance Considerations
- Stability vs. steering: Wider stance improves lateral stability but can reduce immediate steering response on tight trails.
- Ground clearance: Wider wheels can slightly lower clearance; verify clearance with body panels and suspension travel.
- Maintenance: Brass parts may corrode in moisture; clean and dry after use to extend life.
FAQ
- What does a 12mm widener do for RC cars?
A 12mm widener increases track width, improving stability and off-road performance by widening the stance and distributing loads more evenly.
- Will wider wheel widener affect steering?
Yes, a wider track can slightly slow steering response, especially in tight turns, but it improves cornering stability on rough terrain.
- Are brass or aluminum widener better?
Brass is heavier and very durable, good for heavy-duty applications. Aluminum is lighter, which helps with overall efficiency and wheel response.
- How do I choose the right offset?
Choose offset based on the desired stance: 12mm for subtle widen, 15mm–17mm for more pronounced stability, and 30mm variants for extreme widen in certain platforms.
- Can I mix widener brands with existing wheels?
It’s best to use matching hub widths and screws to maintain balance and avoid binding or misalignment.
- Do wideners fit all 1/10 scale RC models?
Not all do—check hub diameter, thread pitch, and overall width to ensure compatibility with your specific chassis and tires.
