Yokomo YOKRP-080 3.0 Linear Ultra Shock Spring for Touring and Pan Cars  [YOKRP-080]

Overview and intended use

This Yokomo YOKRP-080 Linear Ultra Shock Spring 3.0 is an RC-scale suspension spring designed for shock assemblies that need a true linear-rate response. The 3.0 marking denotes the spring version and it is aimed at hobby applications such as touring and pan car setups where steady spring behavior is valuable.

Choose this spring when you want uniform compression and rebound characteristics without progressive stiffening. That predictability makes it easier to assess other suspension changes like damper oil, piston size, or preload because the spring rate remains constant through travel.

Installation follows standard shock-spring procedure: remove the shock cap and shaft assembly, slide the old spring off, and fit the new spring onto the shock shaft and spring retainer. Ensure spring seats and retainers are clean and match preload and free length between left and right shocks after fitting.

Tuning notes: swapping springs is a primary method to alter chassis balance and roll behavior. A stiffer linear spring increases resistance through the stroke, reducing body roll and boosting mid-corner support, while a softer linear spring helps compliance and traction on low-grip surfaces. Combine spring changes with small preload adjustments to refine ride height and initial response without immediately changing damper valving.
