Yokomo YOKRP-081 Linear Ultra Shock Spring 3.2 shock spring for R/C suspension tuning  [YOKRP-081]

Linear shock spring overview

This is an R/C-scale linear shock spring intended as a direct replacement for general-purpose shock assemblies. Its naming indicates a 3.2 designation for spring selection, and the part is used where builders adjust shock characteristics to refine handling and ride feel on electric and nitro R/C models.

Installation is standard for coil-over style shocks: 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. Check that the spring is seated squarely on both ends and that the shock shaft moves freely through the spring without binding.

In tuning, linear springs like this serve to change overall spring rate and preload behavior without altering damping. Use identical springs on paired shocks to keep left-right balance, and change preload in small increments when testing track or driving conditions. Record settings so you can return to baseline values after experimentation.
