Yokomo YOKRP-081 Linear Ultra Shock Spring 3.2 for R/C Suspension Tuning  [YOKRP-081]

Overview of the linear shock spring

This R/C-scale linear shock spring is made to serve as a direct replacement for common shock assemblies. The 3.2 marking denotes the spring rate used when selecting springs, and builders fit this part to refine handling and ride feel on electric and nitro R/C models.

Installation follows standard coil-over shock steps: remove the shock cap and shaft assembly, slide the old spring off the shock body, fit the replacement onto the shock shaft and set preload with the spring collar. Make sure the spring seats squarely at both ends and that the shock shaft moves freely through the spring without binding.

For tuning, linear springs like this adjust overall spring rate and preload behavior without changing damping. Use identical springs on paired shocks to keep left-right balance, change preload in small increments while testing, and record settings so you can return to baseline values after experimentation.
