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.

How often should I refresh the shock oil during heavy use?

Inspect oil after long practice days or after heavy jumps; replace if it darkens or damping feels inconsistent to keep predictable handling.

Can mixing different weights change handling without new shocks?

Yes, blending small amounts of other silicone weights lets you tune rebound and compression without changing springs or pistons. Start with minor ratios and test on the track.

Does the oil affect tyre grip or wear?

The RP-085400A is formulated to avoid leaving residues that alter tyre feel; expect consistent tyre performance across sessions when seals are in good condition.
