Whether you're adjusting for softer handling on rocky terrain, stiffer response on smooth courses, or seeking that perfect middle ground for all-around driving, these springs deliver the engineering precision that separates quality RC products from mediocre alternatives.

Frequently Asked Questions

• What spring rate should I choose for my Rock Krawler shock? — The choice depends on your driving style, terrain and vehicle weight. Softer springs (Yellow 0.4 and White 0.8 rates) provide a more compliant ride on rough terrain, while stiffer springs (Red 1.6 and Blue 2.0 rates) offer more responsive handling and body control on smoother surfaces. The assortment lets you test multiple rates to discover what works best for your specific setup and driving conditions, which is why many experienced RC enthusiasts value having this complete range available.
• How many springs do I need for a complete setup? — This assortment contains enough springs for one complete pair of shocks, meaning you can outfit both sides of your RC vehicle with matching spring rates. If you run dual spring shocks (like the Z-D0048 model), you would have sufficient springs to adjust both the inner and outer springs on one pair of shocks, or the primary springs on both sides of your vehicle.
• Are these springs genuine RC4WD components? — Yes, these are authentic RC4WD Rock Krawler shock springs manufactured to the same quality standards as all genuine RC4WD components. RC Model Shop is an authorised RC4WD retailer, so you can be confident you're purchasing genuine products with full warranty support.
• Can I use these springs on other shock brands? — These springs are specifically engineered for RC4WD Rock Krawler 110mm shocks and the RC4WD Rock Krawler RRD Emulsion Scale Dual Spring Shocks (Z-D0048). While some users may find them compatible with other 110mm shocks, RC4WD cannot guarantee performance or fitment on non-RC4WD suspension components, so we recommend confirming compatibility before purchase if you're using different shock hardware.
• How do I identify which spring rate I'm currently running? — Each spring in this assortment has a colour marking on the bottom: Blue for 2.0 rate, Red for 1.6 rate, White for 0.8 rate, and Yellow for 0.4 rate. Simply remove your current springs and check for these colour markings to identify your existing spring rate.
• What's the difference between the four spring rates? — Spring rate is measured in how much force is required to compress the spring a given distance. The higher the number (2.0 for Blue), the stiffer the spring and the more force needed to compress it. Stiffer springs (higher rates) maintain vehicle ride height better with heavy loads and provide firmer suspension response, whilst softer springs (lower rates) compress more easily to absorb impacts on rough terrain. Having all four rates available lets you fine-tune this critical suspension characteristic.
