The Yokomo YOKRP-078 Linear Ultra Shock Spring 2.6 is an R/C-scale replacement spring designed to work with standard shock assemblies used on radio-controlled cars. It serves as a direct mechanical component for suspension tuning rather than an electronic or motorized upgrade.
In practical setup work this spring is used to alter suspension response and balance; a linear spring keeps progressive force predictable through the travel, which helps when you are testing small changes to preload or damping. Use it as part of stepwise adjustments: change one variable at a time and log results.
Installation is straightforward on most shock units that accept standard spring ends, but confirm spring seating and retainer compatibility before reuse. During service, check for proper alignment, avoid binding at full droop or compression, and verify free piston travel once the shock is reassembled.
