Rear shock spring for pitching damper

This is a setting spring intended for the rear pitching damper on Yokomo R12 scale shocks, supplied in a soft rate that is softer than Yokomo's standard spring. It is sold as a replacement spring to alter rear pitching response without changing shock bodies or pistons.

Installation is straightforward: remove the shock cap and spring retainer, slide off the original spring, and fit the R12-18RSS onto the shock shaft with the appropriate preload and retainer. No proprietary tools are required beyond standard shock service tools and a hex driver for shock end screws.

In tuning terms the softer spring reduces the rear pitch stiffness, which can help with traction and weight transfer on low-grip surfaces or when smoother rear response is desired; pair changes in spring rate with damping and anti-roll adjustments to retain balanced handling.

Remark :

Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What difference does the soft spring make compared to the standard spring?

The soft spring lowers rear pitch stiffness, producing gentler rear weight transfer and increased compliance, which can improve traction on low-grip layouts.

Any installation tips or checks after fitting the spring?

Verify spring preload, shock travel, and that the retainer seats securely; re-check ride height and damping to ensure overall balance after the change.
