The RACEOPT Progressive Dynamic Spring set in yellow and black is a practical upgrade for hobbyists aiming to refine suspension feel. With a T2.5 to T2.6 tension range, these springs deliver a measured, progressive response that helps improve cornering control and overall stability.
Designed to react progressively under load, these springs smooth out transitions between small bumps and heavier compressions. That progressive behaviour helps maintain tyre contact and reduces unwanted pogo or harshness on both smooth tracks and rougher sections.
Installation is straightforward and these springs work with many common shock assemblies, making them an easy swap for most 1/10 and similar RC platforms. They are a solid choice when you want a quick suspension tune without major chassis changes.
