FTX 2.2 Inch Crawler Memory Foam Wheel Inserts 1/10 Scale Rock Crawler FTX8764

Overview

The FTX MAULER 2.2" Crawler Memory Foam inserts are essential upgrade components for serious RC rock crawler enthusiasts in the UK. These premium wheel inserts are specifically engineered to enhance the performance and handling characteristics of compatible FTX crawler models, offering improved traction, comfort, and durability across a wide range of terrain types. Whether you are a seasoned RC competitor looking to fine-tune your trail machine or a dedicated hobbyist seeking to maximise your crawler's potential on challenging woodland courses and rocky landscapes, these memory foam inserts deliver the performance enhancement you need.

Memory foam technology represents a significant advancement in RC crawler tyre insert design. Unlike traditional foam inserts that can harden or lose their properties over time, memory foam maintains consistent performance characteristics whilst adapting to varying terrain conditions. This makes these FTX inserts an intelligent investment for anyone serious about getting the best from their rock crawler. The 2.2-inch size is the industry-standard specification for 1/10 scale rock crawlers, ensuring perfect compatibility with the FTX Kanyon and FTX Mauler model range available from RC retailers across the UK.

These are genuine FTX branded components manufactured to exacting standards, offering the quality and reliability you would expect from an established RC vehicle manufacturer. Each pair comes ready to install, and with their reasonable price point, upgrading your crawler's performance has never been more accessible.

Key Features

• Memory Foam Technology — The foam maintains its shape and performance characteristics through repeated use and temperature variations, providing consistent handling whether you are running your crawler in warm summer conditions or during cooler autumn trail sessions.
• 2.2-Inch Diameter — This is the correct size specification for 1/10 scale rock crawlers, ensuring perfect fitment with FTX Kanyon and FTX Mauler models without any compatibility issues or modification requirements.
• Pair Included — Each package contains two inserts, which is exactly what you need to upgrade a complete set of four crawler wheels (one insert per tyre).
• Front and Rear Compatible — These universal inserts work equally well in front and rear wheel positions, giving you flexibility in how you configure your crawler's suspension setup.
• Enhanced Traction — Memory foam inserts improve grip levels significantly compared to standard alternatives, translating to better control and confidence when navigating technical terrain, rock gardens, and steep hillsides.
• Improved Ride Comfort — The foam provides better shock absorption through the tyre, reducing vibration and harshness transmitted to your crawler's chassis during high-impact rock crawling.
• Terrain Adaptability — Memory foam naturally adapts to varying rock shapes and surface irregularities, maintaining consistent contact patch and maximising traction across unpredictable natural terrain.
• Easy Installation — These inserts require no special tools or complex procedures to install; simply remove your existing inserts and replace them with the new memory foam units.

Technical Performance

Memory foam inserts represent a significant performance upgrade for any 1/10 scale rock crawler. Unlike traditional foam materials that can become brittle in cold weather or lose their cushioning properties through repeated compression cycles, memory foam technology maintains consistent performance across a broader temperature range. These FTX inserts are engineered specifically for rock crawling applications, where precise traction control and terrain feedback are absolutely critical to successful navigation of technical courses. The foam composition provides the ideal balance between firmness and compliance, allowing the tyre to conform to rock surfaces and maintain maximum contact patch whilst still providing the structural support needed to prevent sidewall collapse during extreme articulation manoeuvres. The 2.2-inch specification matches the standard wheel size used on the FTX Kanyon 4x4 RTR crawler, the FTX Kanyon 4x4 Mountain Rescue variant, and the FTX Mauler 2.0 4x4 Rock Crawler in both red and yellow colour options. Installation is straightforward; these inserts simply replace the existing foam inside your tyre sidewalls, requiring no modifications to wheels, tyres, or suspension components. For UK-based RC crawlers who spend significant time exploring woodland trails, forest floors, and natural rock formations, upgrading to memory foam inserts is one of the most cost-effective performance enhancements available.

Frequently Asked Questions

• Are FTX memory foam inserts suitable for all weather conditions? — Memory foam inserts perform excellently in warm and moderate weather conditions. However, user feedback indicates that in cold weather, these inserts can become quite firm, almost solid in extremely low temperatures, which may affect their flex and compliance characteristics. They are ideally suited for spring, summer, and autumn crawling sessions rather than winter use in very cold climates.
• Which FTX crawler models are these inserts compatible with? — These 2.2-inch memory foam inserts are confirmed compatible with the FTX Kanyon 4x4 RTR 1/10 XL Trail Crawler (part number FTX5563), the FTX Kanyon 4x4 Mountain Rescue 2-Speed RTR 1/10 Crawler (FTX5563R), the FTX Mauler 2.0 4x4 Rock Crawler RTR in red (FTX5575R2), and the FTX Mauler 2.0 4x4 Rock Crawler RTR in yellow (FTX5575Y2).
• How many inserts do I need to upgrade my crawler completely? — A pair of inserts is provided in each package, which represents one upgrade set. Since most rock crawlers run four wheels, you would need to purchase two packages if you want to upgrade all four wheels with memory foam.
• What is the difference between memory foam inserts and standard foam inserts? — Memory foam maintains its performance characteristics and shape recovery far better than traditional foam materials, which can become compressed, brittle, or lose their cushioning properties over time. Memory foam provides superior consistency across multiple runs and temperature ranges, offering more predictable handling and longer service life. This makes memory foam a worthwhile investment for serious crawlers.
• Are these inserts easy to install myself? — Yes, these are straightforward to install. Simply remove your existing inserts from your tyres and insert the memory foam replacements. No specialist tools or skills are required, making this an ideal DIY upgrade project for any RC enthusiast.
• What size wheels do these fit? — These are specifically engineered for 2.2-inch diameter wheels, which is the standard size for 1/10 scale rock crawlers. Always verify your wheel size before ordering to ensure compatibility.
