The Kyosho OTW124 Rear Shock Spring Set provides three distinct spring rates - soft, medium and hard - so you can fine tune the OPTIMA rear end for different surfaces and driving approaches. Swap springs to alter rear compliance and responsiveness depending on track layout.
Soft springs increase rear traction on rough or bumpy sections, medium springs target a stable, general purpose balance, and hard springs tighten handling for smooth, high speed tracks. Changing springs is an easy way to refine grip and roll characteristics.
Manufactured to suit Kyosho OPTIMA series rear shocks, these springs install without modification and give a reliable fit. They are a straightforward upgrade to adjust handling without complex parts swaps.
