Silica gel inserts have become increasingly popular in the RC community as users discover their superior performance advantages over conventional foam options. The technology provides excellent cushioning whilst maintaining structural integrity, allowing your tyres to conform more effectively to uneven terrain and maintain consistent contact with the ground. This translates directly into improved traction, better manoeuvrability, and enhanced stability when tackling challenging obstacles and technical crawling sections. The Fastrax brand is renowned throughout the RC hobby for delivering quality parts that provide genuine performance upgrades, and these silica gel inserts are no exception.

Each pack contains four inserts, providing enough components to upgrade a full set of wheels on most RC crawler and small-scale vehicles. Whether you're building a competition-ready rock crawler, a casual trail-basher, or a scale RC model, having quality inserts makes a tangible difference to how your vehicle performs. The superior damping properties of silica gel mean less vibration transfer to your chassis, smoother overall handling, and better shock absorption when navigating rocky terrain, roots, and other natural obstacles. If you're serious about getting the best performance from your ready to run RC crawler or custom-built crawler project, upgrading to silica gel inserts is one of the most cost-effective modifications you can make.

Key Features

• Premium Silica Gel Construction — These inserts are manufactured from high-quality silica gel material, which offers superior damping and cushioning properties compared to traditional foam inserts, resulting in noticeably improved ride quality and vehicle control across all terrain types.
• Precise Sizing for 1.0" Wheels — With dimensions of 55 x 20mm, these inserts are engineered to fit perfectly inside 1.0-inch wheels, ensuring optimal performance and eliminating fitment issues that can occur with generic or incorrectly sized alternatives.
• Set of Four Inserts — The pack includes four silica gel inserts, providing sufficient components to upgrade all four wheels on your RC vehicle, ensuring consistent performance across all four corners of your setup.
• Enhanced Traction and Grip — The silica gel material provides superior grip characteristics, allowing your tyres to maintain better contact with the ground surface, which directly improves traction on loose, rocky, and technical terrain commonly encountered in RC crawling.
• Improved Shock Absorption — The inherent damping qualities of silica gel mean that impacts and vibrations are absorbed more effectively, translating into smoother handling, reduced chassis stress, and better overall vehicle stability during challenging runs.
• Consistent Performance Across Conditions — Unlike some foam inserts which can degrade or compress over time, silica gel maintains its structural integrity and performance characteristics throughout extended use, ensuring reliable, consistent handling session after session.
• Reduced Vibration Transfer — By absorbing and dispersing vibration energy more effectively than foam alternatives, these inserts reduce the transmission of shock and vibration to your vehicle's chassis and electronics, potentially extending the lifespan of your RC components.
• Ideal for Scale Crawlers — These inserts are particularly suited to 1/18th-scale crawlers and similar small-format RC vehicles, though they may also be compatible with other wheel sizes depending on your specific setup.

Technical Performance

Silica gel technology represents a significant advancement in insert engineering for RC vehicles. The material's unique molecular structure provides exceptional damping characteristics that outperform traditional polyurethane foam in numerous measurable ways. When a wheel equipped with a silica gel insert encounters an obstacle, the gel material gradually deforms to absorb the impact energy, then returns to its original shape without the permanent compression that often affects foam inserts. This means your inserts maintain consistent performance throughout your entire RC session, rather than degrading as they're used. The 55 x 20mm dimensions specified for these inserts are precision-engineered to fit 1.0-inch wheel diameters, ensuring that the material fills the wheel cavity completely without leaving air gaps or requiring excessive compression. This full contact between the insert and wheel rim is critical for optimal performance, as any voids would reduce damping effectiveness and create inconsistent handling. The silica gel formula used in these Fastrax inserts has been specifically developed for RC applications, meaning it possesses the correct balance of firmness and compliance to provide effective cushioning whilst still allowing sufficient tyre flex for proper grip and manoeuvrability. Users report noticeably improved handling characteristics, reduced bouncing over rocks and roots, and better overall vehicle control when upgrading from foam to these silica gel inserts. The material is also resistant to UV damage and chemical degradation from fuels and oils, making these inserts reliable even in outdoor environments and during extended storage.

Frequently Asked Questions

• What are silica gel inserts and why are they better than foam? — Silica gel inserts provide superior damping compared to traditional foam options because the gel material maintains its performance characteristics throughout use without compressing or degrading. Foam inserts can permanently compress with use, losing their effectiveness, whereas silica gel consistently returns to its original shape, delivering reliable, predictable handling session after session. For RC crawlers and technical vehicles, this consistency translates to improved grip, reduced vibration, and better overall vehicle control.
• Will these inserts fit my RC crawler? — These inserts are specifically sized for 1.0-inch wheels measuring 55 x 20mm. If your RC vehicle uses 1.0-inch wheels with these exact dimensions, they will fit perfectly. Fastrax also manufactures silica gel inserts in other sizes, including 108 x 42mm for 1.9-inch wheels, so if your vehicle uses different wheel sizes, check whether alternative options are available that match your specifications.
• Are these suitable for beginners to RC crawling? — Yes, absolutely. Whilst these are genuinely performance-enhancing components, they're not complex to install and the improvements they provide make them ideal for anyone looking to upgrade their RC crawler. Installing new inserts is as simple as removing your old inserts and pressing in the new silica gel versions. Beginners will immediately notice improved handling and control, making their crawling experience more enjoyable and their learning curve less steep.
• How do I install silica gel inserts in my wheels? — Installation is straightforward: simply remove your existing foam inserts from your wheels, clean out any debris from the wheel cavity, and firmly press the new silica gel inserts into place. The inserts should fit snugly in the wheel, creating a secure contact throughout the insert area. No gluing or special tools are required.
• How long do these inserts last? — Silica gel inserts are engineered for extended durability and maintain their performance characteristics far longer than foam alternatives. With proper care and normal RC use, a set of quality silica gel inserts can remain effective for seasons of regular use. They won't compress or degrade the way foam does, making them an excellent value investment for your RC crawler.
• Can I use these on ready to run RC crawlers? — Yes, these Fastrax silica gel inserts are compatible with any RC crawler or small-scale vehicle that features 1.0-inch wheels with 55 x 20mm dimensions, whether your vehicle is a ready to run RTR model or a custom-built crawler. Simply remove the existing inserts and install the silica gel versions.
• What is the difference between these 1.0" inserts and the larger 1.9" inserts? — The key difference is size and application. These 55 x 20mm inserts are designed for smaller 1.0-inch wheels commonly found on 1/18th-scale crawlers and compact RC vehicles, whilst the 108 x 42mm inserts are intended for larger 1.9-inch wheels used on bigger crawlers and general off-road RC vehicles. Choose the insert size that matches your wheel specifications for optimal performance.
