Tuning spring for the YR-X12 front push rod

This is a direct replacement front push rod spring from Yokomo for the 1/12 race chassis YR-X12. The set includes two springs, rated 4.5 volumes and finished in black. They mount on the front push rod assembly and allow precise adjustments to roll balance and front-end bite on circuit setups.

Use these springs when you need a firmer or quicker front response in bumpy sections or to moderate understeer during acceleration. Fitting is done on standard push rod assemblies; swap springs one side at a time and recheck geometry and ride height after installation. No special RC tools are necessary.

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.

Are these springs robust for repeated racing?

The springs are designed for competition use. Regular inspection for wear or distortion is recommended after repeated hard use.

Will the black finish affect performance?

The black coating is cosmetic and does not change the specified 4.5 volume rating or spring behavior.

How do these change handling compared to stock springs?

A 4.5 volume spring gives a firmer front response, reducing roll and improving turn-in. Test in small increments to tune to your track conditions.
