Overview

Upgrade your RC crawler’s ride with INJORA’s Silicone Rubber Insert, engineered for 118-122 mm rims and 4.75" outer diameter tires. The inserts are crafted from silicone rubber to deliver a balance of flexibility and support, helping tires maintain their shape through tough terrain without sacrificing responsiveness.

Available in a color-coded range, these inserts are designed to suit different crawler weights and terrains. The result is a more controlled feel when navigating obstacles, with an emphasis on grip and stability rather than guarantee of performance in every condition.

Key benefits

• Waterproof and temperature resistant construction keeps handling consistent across seasons and weather.
• Enhanced sidewall support helps tires hold their shape during side loads and uneven terrain.
• Improved traction and grip can support confident climbs over rocks, roots, mud, and other challenging surfaces.
• Color-coded firmness paired with weight options gives you flexibility to tailor feel to your rig.

Weight options and color coding

• Yellow – soft, about 69 g

Note: each color corresponds to a practical range intended for different crawler weights. Use the color/weight mapping as a guide to balance grip, tire compliance, and control on varied courses.

Fitment and care

Designed for 118-122 mm rims with a 4.75" outer diameter tire and 1.9" wheels, these inserts integrate smoothly into your current setup. For best results, rinse after use, avoid harsh solvents, and inspect fit periodically to maintain tire integrity and performance.

Real-world use cases

From rocky outcrops to slick shale and loose gravel, the inserts offer a more predictable edge by helping the tire keep its contour under load. Use them to fine-tune grip for your typical terrain, weight class, and driving style without committing to a single hard specification.
