YR-X12 front push rod spring details

This replacement front push rod spring is produced by Yokomo for the 1/12 competition chassis YR-X12. The pack contains 2 pcs rated at 4.5 volumes, finished in black. The spring fits onto the front push rod assembly and is used to refine roll control and front-end response for race setups.

Choose this spring when you want a specific rate for snappier response in rough sections or to adjust front bite under acceleration. Installation on standard push rod assemblies is simple: change one side at a time and recheck ride height and geometry after fitting. No specialty tools are required beyond common RC hand tools.

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 comes in the box with the YX-39SB?

The pack contains two Yokomo YX-39SB front push rod springs, each rated at 4.5 volumes.

Can I use these on other 1/12 cars?

They are specified for YR-X12 and YR-X1219. They may fit other models only if the push rod length and retainer style match the originals.

Any tips for swapping springs without upsetting setup?

Replace one spring at a time, then measure ride height and toe to ensure geometry is retained. Run short tests and adjust incrementally to judge handling effects.
