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.

Can I mix these with front springs of a different rate?

Mixing rear DOT5 YS-12105R springs with a different front rate is common to tune balance; just make incremental changes and test each configuration.

Are these springs pre-tempered for longevity?

Yokomo manufactures springs to resist fatigue, but regular inspection and swapping pairs when wear appears will keep on-track performance consistent.

Which shock oil pairs well with DOT5 springs?

Choose a middle-weight oil for 13mm big bore shocks and adjust by +/-10 wt depending on damping feel; the DOT5 springs provide a predictable baseline.

Do these springs require special spring retainers?

They use standard retainers for 13mm big bore shocks, but confirm your shock cap and lower cup fit before installation.
