G-RCO-CR030

Overview

The RCO Dual Inserts, Hard TPE + Foam 1.9 inch 117mm (Pk4) G-RCO-CR030 represent a sophisticated solution for RC enthusiasts across the UK seeking to optimise their rock crawler and scale RC vehicle performance. Manufactured by RC Overhaul, these premium foam inserts deliver a progressive feel with intelligent dual-stage firmness construction that sets them apart from standard single-density alternatives. Whether you're a dedicated rock crawler pilot, a weekend basher tackling challenging terrain, or someone exploring the diverse world of RC off-road vehicles in the UK, these inserts offer the performance characteristics needed for consistent, controlled handling across varied driving surfaces.

What makes these inserts truly special is their clever engineering approach to tyre support and ground feedback. The dual-stage, progressive firmness design incorporates a soft outer ring that works in harmony with stiffer support rings, creating a more like triple firmness experience that adapts to your driving conditions. This innovative construction method means you get the best of both worlds: the ability to soak up small edges, rocks and bumps without sacrificing the sidewall support you need when tackling steep angles and demanding terrain. For anyone running 1.9 inch tyres on their RC crawler or truggy, these inserts represent a genuine upgrade that will transform how your vehicle responds to the ground beneath it.

Supplied in a convenient pack of four inserts suitable for both front and rear positions, the RCO Dual Inserts offer genuine versatility. The hard TPE foam construction ensures durability and consistency through countless hours of RC action, making them an excellent investment for serious hobbyists. Available at RC Model Shop, the UK's trusted RC retailer, these inserts deliver the performance reliability you expect from an authorised distributor of quality RC components.

Key Features

• Dual-stage progressive firmness design — Rather than using a single density foam, these inserts feature multiple rings of varying stiffness that work together to provide soft ground feedback on small obstacles whilst maintaining firm sidewall support for steep angles and demanding terrain, giving you a triple firmness experience in a dual design.
• Soft outer ring for edge absorption — The outer foam layer is specifically engineered to soak up small rocks, roots and edges, preventing harsh impacts from reaching the tyre sidewalls and maintaining smooth, predictable handling across rocky or uneven surfaces.
• Stiffer support rings for angle stability — The inner rings provide substantial resistance and support, preventing excessive tyre deformation on steep climbing angles and maintaining structural integrity during aggressive rock crawling manoeuvres.
• Hard TPE foam construction — The utilisation of hard TPE (thermoplastic elastomer) foam ensures these inserts maintain their performance characteristics through extended use, resisting compression and degradation that softer foams might experience.
• Pack of four inserts — Receiving four inserts allows you to outfit both front and rear positions on your 1.9 inch tyred RC crawler or truggy, ensuring consistent performance across all four wheels.
• Front and rear compatibility — Designed for use in either front or rear positions, these inserts provide genuine flexibility in how you configure your vehicle's suspension and handling characteristics.
• Precise dimensional consistency — The 117mm outside diameter, 55mm inside diameter and 40mm width ensure perfect fitment with 1.9 inch tyres, eliminating installation hassles and ensuring reliable performance from day one.
• Suit rock crawler and scale applications — Engineered specifically for the demanding requirements of rock crawler and scale 1:10 vehicles, these inserts are optimised for the low-speed technical driving that defines these disciplines in the UK RC hobby community.

Technical Performance

The RCO Dual Inserts deliver measurable performance improvements through their sophisticated dual-stage foam engineering. The construction utilises hard TPE foam material throughout, selected specifically for its durability, consistency and resistance to compression fatigue that occurs through repeated cycles of rock crawling and technical terrain navigation. The dimensional specifications — 117mm outer diameter, 55mm inner diameter and 40mm width — have been precisely calculated to work with 1.9 inch scale tyres, ensuring that the foam density and sidewall support characteristics remain optimal under the stresses of controlled rock crawling, steep angle climbing and obstacle navigation. The progressive firmness approach means that as you apply pressure to the tyre, the softer outer ring compresses first to absorb initial impact, then the stiffer inner rings engage to provide stable sidewall support and prevent excessive deformation. This engineering philosophy is particularly valuable for 1:10 scale crawlers where precise wheel articulation and ground feedback are critical to successful navigation of technically demanding courses. The rock crawler classification and 1:10 scale designation confirm these inserts are optimised for low-speed, high-precision applications rather than high-speed bashing, making them ideal for anyone serious about scale realism and technical capability in their RC crawler.

Frequently Asked Questions

• What are foam inserts and why do I need them for my RC crawler? — Foam inserts are internal components placed inside your tyres that provide structural support, ground feedback and impact absorption. For RC crawlers and scale vehicles in the UK, quality inserts like the RCO Dual Inserts are essential because they maintain tyre shape during climbing, prevent excessive deformation on obstacles, and provide the precise ground feedback needed for technical rock crawling and scale challenges.
• What is the difference between these dual-stage inserts and standard single-density foam? — Standard foam inserts typically use a single density throughout, whereas the RCO Dual Inserts employ multiple rings of varying stiffness. This means the soft outer ring soaks up small edges and rocks for comfort and control, whilst the stiffer inner rings prevent tyre deformation on steep angles. This progressive approach gives you better overall performance across a wider range of terrain types and driving scenarios.
• Are these inserts suitable for rock crawling competitions? — Yes, these inserts are specifically engineered for rock crawler applications and scale 1:10 vehicles, making them suitable for competitive and recreational rock crawling across the UK. The dual-stage design is particularly valuable for technical courses where you need both ground feel and sidewall stability.
• What tyres are these inserts compatible with? — These inserts are designed for 1.9 inch (117mm) tyres. They feature a 55mm inner diameter and 40mm width, ensuring proper fitment and performance with standard 1.9 inch scale tyres used on rock crawlers and scale trucks.
• Can I use these on the front and rear of my vehicle? — Yes, the RCO Dual Inserts are specified as suitable for both front and rear positions, providing complete flexibility in how you configure your crawler or truggy suspension setup.
• How long will these foam inserts last? — The hard TPE foam construction ensures durability and resistance to compression fatigue through many hours of use. Lifespan depends on driving intensity and terrain type, but quality hard TPE foams like these are engineered to maintain performance characteristics significantly longer than softer foam alternatives commonly found on budget RC products in the UK.
• What makes hard TPE foam better than other foam materials? — Hard TPE (thermoplastic elastomer) provides an excellent balance of performance characteristics, resisting compression and degradation through repeated impact cycles. This material choice ensures the inserts maintain consistent firmness and support characteristics throughout their service life, unlike softer foams which can break down or compress over time.
