Overview
The SWEEP ROCK CRAWLER 1.9" Medium Double Stage Inserts (2PC) represent a professional-grade tyre insert solution designed specifically for 1/10th scale rock crawling enthusiasts across the UK. These inserts are engineered for rock crawler tyres measuring 1.9 inches, making them an essential component for builders seeking precision and performance in their RC crawler builds. Whether you're competing in organised rock crawling events, tackling challenging off-road terrain, or building a dedicated crawler setup, these medium-rating double stage foam inserts deliver the consistency and durability required for serious RC crawling applications.
Supplied as a pair, these inserts are manufactured by Sweep, a recognised name in RC tyre technology and foam insert design. The double stage construction represents a significant advancement in tyre insert engineering, offering improved performance characteristics compared to single-stage alternatives. For RC enthusiasts in the UK searching for reliable rock crawler inserts that offer proven performance and compatibility with industry-standard 1.9-inch crawler tyres, this product delivers exceptional value and proven engineering.
Rock crawling has become an increasingly popular discipline within the broader RC hobby community. Unlike traditional off-road RC racing, rock crawling demands precise vehicle control, exceptional traction in challenging terrain, and components that can withstand extreme conditions. The right tyre inserts make a dramatic difference in how your RC crawler performs, affecting ground contact, weight distribution, and overall responsiveness during technical crawling manoeuvres.
Key Features
- Double Stage Foam Construction — The dual-stage design of these inserts provides enhanced performance characteristics that deliver superior traction and stability compared to single-stage alternatives, making them the preferred choice for serious rock crawling applications.
- Medium Rating Profile — The medium specification ensures these inserts deliver a balanced blend of responsiveness and durability, suitable for varied rock crawling terrain and conditions without requiring frequent adjustments or replacements.
- 1.9-Inch Compatibility — These inserts are precisely engineered for 1.9-inch rock crawler tyres, ensuring perfect fitment and eliminating the sizing concerns that often plague aftermarket tyre insert purchases for UK RC builders.
- Supplied as a Pair — Each package contains two inserts, providing complete coverage for a standard four-wheel RC rock crawler setup when purchased in appropriate quantity, simplifying your purchasing decision.
- Professional-Grade Materials — Sweep's foam insert technology utilises quality materials engineered to withstand the demanding punishment of serious rock crawling, from sharp rock edges to extreme compression forces during technical manoeuvres.
- Dimensional Precision — With an outer diameter of 116mm and width of 39mm, these inserts are manufactured to exacting tolerances, ensuring consistent performance and eliminating the loose fitment issues that compromise handling and traction.
Technical Performance
The SWEEP ROCK CRAWLER 1.9" Medium Double Stage Inserts represent a carefully engineered solution that addresses the specific demands placed on rock crawler components. The double stage foam construction utilises a sophisticated layering system that provides differential support characteristics — delivering firm support where needed whilst maintaining the flexibility required for excellent ground contact across uneven rock surfaces. The medium rating classification positions these inserts in the optimal range for general-purpose rock crawling, offering responsiveness that rewards precise driving inputs whilst maintaining the structural integrity required for aggressive terrain. The specified outer diameter of 116mm and width of 39mm are engineered for seamless integration with 1.9-inch rock crawler tyres that require inserts of these exact dimensions. For UK RC enthusiasts working with compatible crawler setups, these inserts represent a reliable upgrade that directly improves vehicle performance through enhanced traction, reduced wheel slip on technical sections, and improved overall vehicle stability during extreme crawling manoeuvres. The foam technology employed in these inserts is specifically formulated for the abrasive environments encountered during rock crawling, where tyres must maintain contact with sharp, irregular surfaces whilst enduring repetitive compression cycles that would degrade inferior materials more rapidly.

Frequently Asked Questions
- What are tyre inserts and why do I need them for my RC rock crawler? — Tyre inserts are foam components that fit inside RC tyres to modify their performance characteristics. For rock crawlers specifically, inserts are essential because they dramatically improve traction on rocky, uneven surfaces, reduce wheel slip during technical climbing sections, and provide the precise weight distribution needed for extreme terrain. Without quality inserts, rock crawler tyres become too soft and squishy, leading to poor handling and reduced climbing ability.
- Are these inserts compatible with my 1.9-inch rock crawler tyres? — Yes, these SWEEP inserts are specifically engineered for 1.9-inch rock crawler tyres that require inserts with an outer diameter of 116mm and width of 39mm. If your tyres match these dimensions, these inserts will provide perfect fitment. We recommend checking your tyre specifications before ordering to ensure compatibility.
- What does double stage foam construction mean? — Double stage foam construction refers to a two-layer design within the insert that provides different support characteristics at different compression levels. The dual-layer approach delivers improved performance by offering firm support during hard impacts and extreme compression whilst maintaining the flexibility needed for excellent ground contact on irregular surfaces, resulting in better overall traction and handling compared to single-stage alternatives.
- How long do these inserts last before requiring replacement? — The lifespan of tyre inserts depends on your usage intensity, the specific terrain you crawl, and your driving style. The medium-rating foam used in these Sweep inserts is engineered for durability and should provide extended service life for regular recreational crawling. Competitive users who engage in intensive crawling sessions may require more frequent replacements, whilst casual users will find these inserts provide excellent longevity.
- Can I use these inserts with different tyre brands? — Compatibility depends on the tyre's internal dimensions rather than the brand name. These inserts are suitable for any 1.9-inch rock crawler tyre that requires inserts with 116mm outer diameter and 39mm width. We recommend measuring your tyres or consulting your tyre manufacturer to confirm compatibility before purchase.
- Are these suitable for beginners in rock crawling? — Yes, absolutely. The medium rating profile makes these inserts suitable for crawlers of all experience levels. Beginners will appreciate the balanced performance characteristics that make vehicle handling predictable and responsive, whilst experienced crawlers will recognise the quality engineering and performance benefits. These are not specialist competition-only products — they're designed for general rock crawling applications.
- What is the difference between medium and soft or hard insert ratings? — Insert ratings (soft, medium, hard) refer to the foam's density and compression characteristics. Medium inserts, like these, offer balanced performance — they're more responsive than soft inserts but more forgiving than hard inserts. For most UK rock crawling applications across varied terrain, medium inserts provide the optimal combination of traction, durability, and handling responsiveness.
