Overview
The Kyosho Shock Spring (3.8 Rate) is a firm, precision-wound spring designed for compact short-stroke shock applications. With a 1.2mm wire diameter, 5mm inner diameter, and 44mm free length, these springs deliver controlled response ideal for high-grip surfaces and aggressive driving where minimal chassis roll is required.
As the stiffest option in the W5312 series, the 3.8 rate springs provide firm suspension support and quick response, making them excellent for high-traction tracks or heavier vehicle setups that require reduced suspension compression.
