Technical Performance

Silica gel wheel inserts represent a significant advancement in RC component technology. Unlike traditional foam inserts that gradually compress and lose their shock-absorbing properties through use, silica gel maintains its structural characteristics and performance benefits through extensive driving sessions. The 108 x 42mm dimensions of these inserts are engineered to fit within 1.9-inch wheels, which are standard across numerous RC car platforms including buggies, trucks, and short-course vehicles. The silica gel construction provides superior damping properties, which means it absorbs impact energy more efficiently when your RC vehicle lands from jumps or encounters rough terrain. This translates directly into reduced stress on wheel rims, tyre sidewalls, and suspension components. Additionally, the consistent pressure maintained by quality silica gel inserts ensures that your tyres maintain optimal contact with the wheel rim throughout driving, which is critical for achieving maximum grip and traction. Many UK RC drivers report noticeable improvements in handling precision, reduced vibration transmission to the chassis, and enhanced tyre longevity when upgrading from standard foam to premium silica gel inserts. The engineering quality of Fastrax products means these inserts will maintain their performance characteristics for extended periods, making them a cost-effective upgrade that delivers genuine performance benefits for competitive drivers, weekend enthusiasts, and anyone serious about maximising their RC vehicle's potential.

Frequently Asked Questions

• What are wheel inserts and why do I need them for my RC car? — Wheel inserts are internal components that sit inside your RC vehicle's wheel to provide shock absorption, improve tyre grip, and protect wheel rims from damage. They're essential for any RC car enthusiast because they dramatically improve handling, reduce vibration, protect your suspension from impact damage, and extend the lifespan of both tyres and wheels. Many UK RC drivers consider quality inserts non-negotiable for any vehicle they plan to drive regularly.
• What's the difference between silica gel and foam wheel inserts? — Silica gel inserts are far superior to traditional foam alternatives because they maintain their structural integrity and performance characteristics much longer. Foam compresses over time and loses shock-absorbing properties relatively quickly, whereas silica gel remains consistent through hundreds of driving sessions. This means silica gel inserts provide longer-lasting performance, better shock absorption, improved grip consistency, and ultimately better value for money.
• Will these inserts fit my 1.9" wheels? — These Fastrax inserts are specifically engineered for 1.9-inch wheels with 108 x 42mm dimensions. If your wheels match these specifications, the inserts will fit perfectly without modification. The 1.9-inch wheel size is standard across many popular RC platforms, including numerous buggies and trucks available in the UK market, so compatibility is likely if you're running mainstream RC equipment.
• How many inserts do I need? — For a standard four-wheel RC vehicle, you typically need four inserts (one per wheel). This pack contains exactly four inserts, which means it provides one complete set for a single vehicle. If you want to maintain spare sets or have multiple vehicles, you may want to purchase additional packs.
• How do I install wheel inserts? — Installation involves carefully removing your tyre from the wheel rim, placing the insert inside the wheel, and then re-mounting the tyre. The silica gel insert should sit comfortably inside the wheel without requiring force or modification. If you're unfamiliar with tyre installation, our team at RC Model Shop can provide guidance or perform the installation for you.
• Will wheel inserts improve my lap times? — Yes, quality wheel inserts can improve your lap times by providing better tyre grip, more consistent handling, and reduced vibration that interferes with control precision. Many competitive RC drivers report noticeable improvements in consistency and cornering speed after upgrading to premium silica gel inserts, making them particularly worthwhile for anyone pursuing competitive driving.
• How long do Fastrax silica gel inserts last? — Silica gel inserts from Fastrax are engineered for durability and will typically outlast traditional foam alternatives by a significant margin. With proper care and normal usage, these inserts should remain effective through hundreds of driving sessions before requiring replacement, making them excellent value compared to foam options that degrade much faster.
