Engineered for the 1/18 TRX4M, they leverage the density of brass to achieve a lower center of gravity. This isn't just about adding weight; it's about strategic weight distribution that directly translates to improved handling, reduced body roll, and enhanced traction on uneven surfaces. The precision manufacturing ensures a snug fit, integrating seamlessly with your vehicle's existing components for immediate performance gains. Experience the difference that quality materials and thoughtful design make in your RC adventures. **Ideal for Enthusiasts, Consider for Beginners** — These brass hex extenders are perfect for RC enthusiasts looking to fine-tune their 1/18 TRX4M's handling and stability for off-road crawling. If you frequently encounter inclines or uneven terrain, the improved anti-rollover performance will be a significant benefit. However, beginners or those primarily driving on flat surfaces might not notice a substantial difference, and the added weight could be less critical. Ensure your RC car's scale and hex hub size (5mm) are compatible before purchasing. ## How to use 1. Gather your tools and ensure your 1/18 TRX4M RC car is on a stable surface. Identify the existing wheel hubs and axle pins that need to be replaced with the new brass components. — Prepare for Installation 2. Carefully remove the stock wheel hubs from each wheel of your TRX4M. This typically involves unscrewing or releasing a small retaining mechanism. Set aside the original parts. — Remove Existing Hubs 3. Align the new INJORA Brass Wheel Hex Hub Extenders with the axle pins. Insert the axle pins through the hex hubs and into the car's axle holes, ensuring a secure fit for all four wheels. — Install Brass Hex Extenders 4. Once the hex extenders are in place, reattach any retaining mechanisms. Double-check that all wheels are securely fastened and spin freely. Test drive your RC car to feel the improved stability and handling. — Secure and Test ## Product details | Field | Value | |---|---| | Package Contents | 4 * Brass Wheel Hexes, 4 * Axle pins | | Unit Count | 8 pieces total (4 hexes + 4 pins) | | Installation | Direct replacement for existing wheel hubs; requires manual installation. | | Age Range | Recommended for ages 14+ | | Brand | INJORA | | Part Number | TRX4M-02-5 | | Material | Brass | | Color | Gold | | Width | 5mm (0.2in) | | Thickness Options | 5mm / 6mm (optional) | | Vehicle Scale | 1/18 | | Compatible Model | TRX4M RC Crawler Car | | Theme | Off-road | | Operation Mode | Manual | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### Will these RC wheels and tires fit my remote control car? Fitment depends on the hex hub size (commonly 12mm or 17mm) and the wheel diameter/width in mm listed in the product details. For these INJORA Brass Wheel Hex Hub Extenders, they are specifically designed for the 1/18 TRX4M model with a 5mm hex hub size. Match these figures to your chassis scale to confirm compatibility before ordering. ### Do these tires come pre-mounted on rims with foam inserts? These INJORA Brass Wheel Hex Hub Extenders are components that attach to your existing wheels and tires. They do not include tires or rims themselves, nor do they come pre-mounted. The package contains 4 brass hex extenders and 4 axle pins, which are installed onto your current wheel setup. ### How do these brass hex extenders improve RC car performance? The brass material is significantly heavier than stock plastic or aluminum, lowering the vehicle's center of gravity. This increased weight distribution improves stability, reduces body roll, and enhances the anti-rollover performance, making your 1/18 TRX4M RC crawler more capable on uneven terrain and inclines. ### What is the benefit of extending the wheel distance with these hubs? Extending the wheel distance with the 5mm hex hubs creates a wider track width. This wider stance improves overall stability and can prevent the tires from interfering with steering components, allowing for better articulation and steering response during aggressive driving. ### Are these INJORA hex extenders suitable for off-road use in India? Yes, these INJORA Brass Wheel Hex Hub Extenders are designed for off-road use and are suitable for Indian conditions. Their enhanced stability and anti-rollover features are beneficial for navigating varied terrains. All customs duties and GST are included in the price, with ExpressBox tracked delivery. ### How to install INJORA Brass Wheel Hex Hub Extenders? Installation involves removing your existing wheel hubs from the 1/18 TRX4M RC car, aligning the new brass hex hubs with the axle pins, inserting the pins through the hubs and into the car's axle holes, and securing them. Repeat for all four wheels. ### What is the difference between 5mm and 6mm hex extenders? The 5mm and 6mm options refer to the thickness of the hex extender, which dictates how much further out the wheel is positioned from the axle. A wider stance (achieved with thicker extenders) generally increases stability and can improve handling, but the specific choice may depend on your RC car's setup and desired track width. ## Compliance No product-specific compliance warnings identified.
