Overview
The Kyosho Shock Spring (2.0 Rate) is the softest option in the W5313 series, designed for maximum mechanical grip and suspension compliance on challenging track conditions. With a 1.2mm wire diameter, 9.25mm inner diameter, and 61mm free length, these springs deliver progressive compression that keeps tires planted over bumps and rough terrain.
Sold as a matched pair, the 2.0 spring rate excels on low-grip, bumpy, or technical tracks where increased suspension compliance is critical for maintaining traction and control.
