Frequently Asked Questions
- What does the 4.075 spring rate mean for my RC car's handling? — The spring rate indicates how stiff the spring is; a 4.075 rate provides a balanced setup suitable for general driving, offering good bump absorption whilst maintaining responsive handling characteristics. Higher rates stiffer springs for faster tracks, lower rates softer springs for rough terrain — the 4.075 is a versatile choice for most RC driving situations.
- Why is the green stripe colour coding important? — The colour stripe allows you to instantly identify the spring rate during setup, tuning, and maintenance, preventing confusion when managing multiple spring rates across different vehicles or chassis configurations, and ensuring you maintain consistent suspension specifications.
- Are these springs compatible with my Traxxas RC vehicle? — These are genuine Traxxas original equipment suspension components designed to fit Traxxas shock absorbers; compatibility depends on your specific vehicle model, so please verify compatibility with your vehicle's documentation or contact our experienced team for guidance on fitment.
- How often should I replace my shock springs? — Shock springs can last a very long time with proper care, but should be replaced if they become bent, damaged, or lose their spring characteristics due to fatigue or wear, or when upgrading your suspension geometry for different track conditions or driving styles.
- What is the difference between this spring and other available rates? — Traxxas offers multiple spring rates for different driving preferences; softer springs (lower rates) provide better bump absorption and traction on rough terrain, while stiffer springs (higher rates) deliver better response on smooth surfaces and faster tracks — the 4.075 rate offers balanced performance for versatile driving situations.
- How do I install these shock springs on my RC car? — Shock spring installation typically involves removing your shock absorber from your vehicle, carefully disassembling it, removing the old spring, installing the new TRX8363 spring, and reassembling according to your vehicle's manual — if you're unfamiliar with suspension work, our experienced RC shop team can provide guidance or installation support.
