Overview
The ARRMA Shock Spring Front 70mm (2): 4x4 BLX 4S is an essential replacement suspension component designed for ARRMA 4x4 BLX 4S RC vehicles. These high-quality shock springs are precision-engineered to deliver consistent suspension performance and maintain the handling characteristics of your RC car UK setup. Whether you're a weekend basher enjoying off-road adventures or a competitive racer pushing your brushless RC 4WD to its limits, replacement shock springs are a critical part of regular maintenance and tuning. Over time, suspension components wear and lose their spring rate, affecting your vehicle's ride quality, cornering stability and overall performance. These genuine ARRMA shock springs restore your suspension to factory specifications and ensure your ready to run RC 4x4 BLX performs exactly as intended.
Suspension maintenance is one of the most important aspects of keeping your RC car in peak condition, and having genuine replacement parts on hand means you can keep your vehicle race-ready or bash-ready at all times. The 70mm front shock springs are manufactured to ARRMA's exacting standards using strong spring steel, ensuring they provide long-lasting durability and consistent performance throughout their lifespan. These springs are compatible with the ARRMA 4x4 BLX 4S range, making them an authentic OEM choice for owners who demand quality and reliability from their RC vehicle parts.
If you're looking to maintain your ARRMA 4x4 BLX 4S in peak condition or need to refresh tired suspension components, these shock springs are an excellent investment. Suspension springs gradually lose their spring rate through normal use, and replacing them with genuine ARRMA parts ensures you maintain the vehicle's original handling balance and performance characteristics. Available now at RC Model Shop, these are the genuine replacement parts your brushless electric RC 4x4 deserves.

Technical Performance
These ARRMA shock springs deliver precise suspension tuning for the ARRMA 4x4 BLX 4S brushless electric RC 4x4. Measured at 70mm in length with an inner diameter of 21mm (0.83 inches), these springs provide a spring rate of 4.57lb/in, equivalent to 0.8N/mm, making them suitable for general driving and bashing applications on this platform. The springs are manufactured from high-quality spring steel, a material chosen specifically for its ability to maintain consistent spring rate over extended periods of use. Unlike lower-grade alternatives that may lose their characteristics quickly, genuine ARRMA springs are engineered for durability and long-lasting performance. The precision manufacturing ensures that both springs in the pair have identical characteristics, maintaining balanced suspension geometry across both front corners of your vehicle. This is critical for achieving predictable handling, consistent cornering grip and stable acceleration characteristics. The 4.57lb/in stiffness rating makes these suitable for a variety of driving conditions and user weights, whether you're a lighter beginner driver or a heavier experienced pilot. For users running their ARRMA 4x4 BLX 4S in competitive environments or high-speed bashing, having fresh suspension springs is essential to maintaining the engineered suspension geometry that ARRMA designed into these vehicles. The springs work in conjunction with the shock absorbers and damper fluid to create the complete suspension system, so refreshing the springs during a suspension overhaul ensures optimal performance across all suspension components.

Frequently Asked Questions
- What vehicles are these shock springs compatible with? — These 70mm shock springs are designed specifically for ARRMA 4x4 BLX 4S RC vehicles. They fit the front suspension positions on this platform. Always verify your vehicle model before ordering to ensure compatibility with your specific ARRMA RC 4x4.
- How often should I replace my RC shock springs? — Suspension springs gradually lose their spring rate through normal use and repeated compression cycles. For regular bashers, replacing springs every 12-24 months or when you notice handling changes is recommended. Competitive racers may refresh springs more frequently depending on track schedule and driving intensity.
- What is the spring rate and why does it matter? — These springs have a stiffness rating of 4.57lb/in (0.8N/mm). Spring rate directly affects how your suspension compresses and rebounds, influencing ride height, handling balance, cornering grip and overall driving feel. Using the correct OEM spring rate ensures your vehicle performs as the manufacturer intended.
- Are these genuine ARRMA parts or aftermarket replacements? — These are genuine ARRMA OEM replacement springs, manufactured to the brand's exact specifications. Choosing authentic ARRMA parts ensures perfect fitment, consistent performance and compatibility with your 4x4 BLX 4S suspension system.
- Do I need any special tools to install these shock springs? — Installation requires removing the shock bodies from your vehicle, which typically involves basic RC tools such as hex keys and possibly a shock spring compressor to safely compress the springs during removal and installation. Many RC enthusiasts already have these tools in their maintenance kit.
- Can I use these springs on other ARRMA vehicles? — These springs are specifically designed for ARRMA 4x4 BLX 4S models. Other ARRMA vehicles may use different spring lengths, diameters or stiffness ratings. Always check your vehicle's manual or the ARRMA parts diagram to verify compatibility before ordering suspension components.
- What makes replacement shock springs important for my RC 4x4? — As springs age through normal use, they gradually lose their spring rate, causing your suspension to sit lower, affecting ride height, ground clearance, handling balance and cornering characteristics. Replacing tired springs restores your vehicle's original suspension geometry and performance, making them essential for maintaining your RC car UK in peak condition.
