Overview

The Fastrax Silica Gel Insert for 1.9" Wheels is an essential upgrade for RC enthusiasts across the UK who demand superior traction and performance from their remote control cars. Designed specifically for 1.9-inch wheels measuring 108 x 42mm, these silica gel inserts are the go-to choice for serious RC hobbyists looking to enhance their vehicle's grip on various track surfaces and terrain types. Whether you're competing in club races, enjoying weekend bashing sessions, or pushing your RC car collection to new limits, these gel inserts deliver the consistent performance and reliability that discerning RC car UK buyers expect from quality components.

Silica gel inserts have become the gold standard in the RC community for improving weight distribution and traction characteristics. Unlike traditional foam inserts, silica gel provides a firmer, more responsive feel that translates to better cornering grip and more predictable handling dynamics. For RC enthusiasts running 1.9-inch wheels on buggies, short course trucks, or touring cars, upgrading to these Fastrax silica gel inserts can make a tangible difference in lap times and overall vehicle control. This pack contains four individual inserts, giving you the complete set needed for all four wheels of your RC vehicle.

Fastrax is a trusted brand within the RC hobby, known for producing precision-engineered components that meet the demands of competitive and recreational drivers alike. These silica gel inserts represent the kind of attention to detail and quality construction that has made Fastrax a respected name among RC communities worldwide. Whether you're upgrading a ready to run RC car or fine-tuning a competition machine, these inserts offer excellent value and performance.

Key Features

• Silica Gel Construction — These inserts are manufactured from premium silica gel material, which offers superior grip characteristics compared to traditional foam alternatives. Silica gel provides a firmer response that helps maintain traction through aggressive cornering and delivers more consistent handling feedback, making it ideal for both track racing and off-road RC applications.
• Perfect Fit for 1.9-Inch Wheels — Manufactured to precise specifications of 108 x 42mm, these inserts are engineered to fit 1.9-inch wheels with absolute precision. This exact sizing ensures that the inserts sit perfectly within your wheel rim without gaps or movement, maximising contact patch and traction transfer to the track surface.
• Complete Four-Piece Set — This pack includes four individual gel inserts, providing a complete set for all four wheels of your RC vehicle. Having matched inserts on all four wheels ensures consistent handling characteristics and predictable vehicle behaviour during acceleration, braking, and cornering manoeuvres.
• Enhanced Weight Distribution — Silica gel inserts improve the weight distribution and balance characteristics of your wheels, which can have a noticeable impact on vehicle dynamics. Better weight distribution leads to improved stability, more predictable handling response, and ultimately faster lap times on competitive tracks.
• Improved Traction and Grip — The firmer nature of silica gel compared to foam means these inserts deliver enhanced grip levels across various track surfaces. Whether racing on asphalt, carpet, or off-road terrain, the improved traction characteristics help maintain acceleration out of corners and reduce wheel slip during hard driving.
• Durability and Consistency — Silica gel inserts maintain their performance characteristics over extended use without the degradation that can affect traditional foam inserts. This means consistent traction and handling feel throughout extended driving sessions, competitive events, and training runs.
• Brand Reputation — Fastrax components are recognised and trusted by RC communities across the UK and internationally. Choosing Fastrax silica gel inserts means investing in components that have been proven in competitive environments and are backed by the brand's reputation for quality engineering.

Technical Performance

These Fastrax silica gel inserts represent a significant upgrade over standard foam wheel inserts for serious RC car enthusiasts. The 108 x 42mm dimensions are specifically engineered for 1.9-inch wheel applications, ensuring perfect compatibility with the broad range of buggies, short course trucks, and touring cars that utilise this wheel size in the RC hobby. The silica gel material is considerably firmer than traditional foam inserts, which has important implications for vehicle performance. This firmness translates to improved weight distribution within the wheel assembly, reducing vibration and providing more direct feedback to the driver. The gel construction resists the compression and degradation that affects foam over time, meaning these inserts maintain consistent performance characteristics throughout extended use. For competitive RC drivers, this consistency is invaluable—it means lap times remain predictable and handling response doesn't degrade as session time accumulates. The improved traction characteristics of silica gel are particularly noticeable when pushing your RC car to the limit on tight technical sections of a race track, where maintaining grip through quick direction changes is critical to competitive performance. Whether you're running on carpet racing circuits common in UK RC clubs, outdoor asphalt tracks, or off-road terrain, these inserts help maximise the grip potential of your 1.9-inch tyres and contribute to faster, more controlled driving experiences.

Frequently Asked Questions

• What is the difference between silica gel inserts and foam wheel inserts? — Silica gel inserts are firmer than traditional foam and provide superior traction and weight distribution characteristics. Foam inserts compress over time and can degrade, whilst silica gel maintains consistent performance throughout extended use. For competitive RC drivers and those seeking improved handling response, silica gel is the preferred choice. The firmer material delivers more direct feedback and better grip consistency across various track surfaces.
• Will these inserts fit my RC car wheels? — These inserts are designed specifically for 1.9-inch wheels with dimensions of 108 x 42mm. If your RC vehicle uses 1.9-inch wheels—common on buggies, short course trucks, and touring cars—these Fastrax inserts will provide a precise fit. Always verify your wheel dimensions before ordering to ensure compatibility with your specific RC setup.
• What types of RC vehicles can use these inserts? — These 1.9-inch wheel inserts are compatible with a wide range of RC applications including 1/10 scale buggies, short course trucks, touring cars, and other RC vehicles equipped with 1.9-inch wheels. They're suitable for both track racing and general recreational driving, whether you're running on indoor carpet circuits, outdoor asphalt tracks, or off-road terrain.
• Are these suitable for beginners or only for competitive drivers? — Whilst silica gel inserts are popular among competitive RC drivers seeking maximum performance, they're also beneficial for recreational drivers and beginners looking to improve their vehicle's handling characteristics. The improved traction and more responsive feel can actually help newer drivers develop better car control skills. However, beginners may want to master their vehicle with standard inserts before upgrading.
• How many inserts do I need? — This pack contains four inserts, which is exactly the complete set needed for all four wheels of a single RC vehicle. Having matched inserts on all wheels ensures consistent handling across the entire vehicle and optimal performance.
• How long do silica gel inserts last? — Silica gel inserts are significantly more durable than foam alternatives and maintain consistent performance over extended use. With proper care, these inserts should provide reliable service through many racing seasons and countless driving hours. Exact lifespan depends on driving intensity and track conditions, but silica gel's resistance to compression and degradation means you'll enjoy consistent performance far longer than foam inserts.
