Yokomo YOKRP-081 3.2 Linear Shock Spring Compatible with R/C Suspension  [YOKRP-081]

Linear spring summary

This R/C linear shock spring is intended as a straightforward replacement for general-purpose shock units. The 3.2 designation indicates the spring rate used during tuning, and the component is used by builders to alter handling characteristics and overall ride feel on electric and nitro R/C vehicles.

Fitting is typical for coil-over shocks: remove the cap and shaft assembly, slide off the existing spring, place the new spring on the shock shaft and set preload using the collar. Confirm the spring sits flush on both ends and that the shaft moves freely without rubbing the coil.

When tuning, linear springs change the overall spring constant and preload response while damping remains unchanged. Install matching springs on paired shocks to maintain balance, make incremental preload adjustments on track tests, and keep a written log of settings so you can revert to prior setups.
