This pair of super soft springs delivers exceptional suspension compliance and articulation, making them ideal for serious RC enthusiasts and competitors who demand precision engineering and reliable performance from their RC car UK setups. Whether you're tackling challenging terrain in the UK or competing in organised RC events, these replacement springs are engineered to provide the perfect balance of comfort and control.
Built to exacting Axial standards, these springs are crafted from high-quality materials and designed for seamless compatibility with a wide range of SCX10 II models. The 2.7lbs/in spring rate classification indicates a super soft suspension characteristic, which is particularly beneficial for rock crawling applications where maintaining tyre contact with uneven surfaces is paramount. These springs represent an upgrade option for those looking to fine-tune their vehicle's suspension characteristics and achieve superior off-road handling across varied terrain types.
For RC enthusiasts searching for quality replacement springs for their brushed RTR rock crawler or looking to upgrade their suspension setup, this product offers genuine Axial engineering backed by decades of off-road vehicle design expertise. The super soft spring rate makes these particularly suitable for building a more compliant suspension system that responds exceptionally well to small obstacles and maintains excellent wheel articulation during technical crawling manoeuvres.
Key Features
- Super Soft Spring Rate (2.7lbs/in) — The 2.7lbs/in spring constant delivers exceptional suspension compliance, allowing your RC crawler to maintain maximum contact with the terrain and absorb impacts more effectively than stiffer alternatives, which directly translates to improved traction and obstacle-clearing capability.
- Compatible with Multiple SCX10 II Models — These springs work as replacement parts and optional upgrades across the entire Axial SCX10 II range, including the '69 Chevrolet Blazer RTR, 1955 Ford F-100 RTR, 2017 Jeep Wrangler Unlimited, Deadbolt 4X4, Jeep Cherokee, Trail Honcho, and UMG10 variants, making them a versatile choice for SCX10 II owners.
- Pair of Two Springs — This package includes two springs, providing you with either a complete axle setup replacement or a spare set for quick maintenance and testing of different suspension geometry configurations on your ready to run RC vehicle.
- Quality Axial Engineering — Manufactured by Axial, a recognised leader in RC scale crawler design, these springs benefit from extensive research and development specifically focused on rock crawling performance, ensuring reliable operation in demanding off-road conditions.
- Direct Replacement and Optional Part — These springs function both as direct replacement components for worn or damaged units and as optional performance upgrades, allowing you to fine-tune your suspension setup to match your driving style and terrain preferences.
Technical Performance
The Axial Spring 12.5x40mm 2.7lbs/in Super Soft Red represents precision engineering designed specifically for the demands of rock crawling and scale RC applications. With a spring constant of 2.7lbs/in, these components deliver exceptional suspension articulation—a critical performance factor when navigating rocky, uneven terrain where maintaining constant wheel contact determines success or failure. The 12.5mm diameter and 40mm length specifications are precisely engineered to fit within Axial's sophisticated suspension geometry, working in harmony with other suspension components to create a balanced, responsive system. The super soft classification means these springs compress more readily than stiffer alternatives, allowing the suspension to travel further through its range of motion and maintain better ground contact over obstacles. This characteristic proves invaluable in UK RC crawling competitions and challenging terrain found across British landscapes, where technical precision and smooth articulation separate competitive performers from casual bashers. The red colour provides excellent visibility during operation and makes identifying spring pairs straightforward when managing multiple setup configurations. Built from durable materials engineered to withstand repeated compression and extension cycles without permanent deformation, these springs deliver consistent performance throughout their operational lifespan, making them a reliable component in any serious RC crawler enthusiast's workshop.

- Are these springs suitable for beginners? — Yes, these replacement springs are suitable for all experience levels. Beginners driving SCX10 II ready to run RC crawlers will benefit from the super soft spring rate as it makes the vehicle more forgiving and easier to control over rough terrain, while experienced competitors can use these springs as part of a deliberate setup tuning strategy.
- Can I use these springs to upgrade my existing SCX10 II? — Absolutely. These springs function as both direct replacements for worn components and as optional performance upgrades, allowing you to fine-tune your suspension characteristics. Testing different spring rates is a common tuning technique among serious RC enthusiasts and competition drivers.
- Why would I choose super soft springs over standard or stiff options? — Super soft springs like these 2.7lbs/in units excel in rock crawling scenarios where maximum articulation and obstacle-clearing capability matter most.
