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 track conditions benefit most from this nut?

High grip and technical tracks benefit from small preload adjustments to fine tune weight transfer and steering. Use the nut to tune for either tighter turns or smoother stability depending on the surface.

How many nuts are supplied per package?

The package contains two sets of adjustment nuts along with O-rings, providing spares and mounting options for front or rear shocks.

Do I need special tools to fit them?

No specialised tools are required beyond common hobby items. A small spanner or nut driver and a careful approach are usually sufficient to install and set the nuts.

Will these change spring rate?

They adjust spring preload rather than spring rate. Preload alters ride height and initial stiffness feel, but does not change the spring's inherent rate.
