Tune Traction and Response with Precision Oil

Yokomo's CS-4000B Super Blend Silicone Oil #4000 helps drivers refine traction and damping response by keeping viscosity stable as temperatures shift. Use it when dialing in shock pistons or when you want predictable diff behavior during long runs or variable conditions.

Why Choose Yokomo CS-4000B Silicone Oil?

The #4000 grade provides a firmer damping feel while resisting thermal thinning, which supports more consistent turn-in and mid-corner balance. It is a practical option for racers tuning handling precision.

Applications and Benefits

Temperature Resistance: Maintains consistent viscosity for reliable performance.
Versatile Use: Suitable for both on-road and off-road vehicles.
Enhanced Control: Ideal for adjusting damping force in friction shocks and optimizing gear differentials.

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 does #4000 oil change shock feel?

A #4000 oil increases damping resistance, yielding firmer shocks; expect slower compression and rebound which can improve stability on high-speed sections.

Should I alter piston or spring settings when using this oil?

Often yes; thicker oil pairs well with larger piston holes or softer springs to maintain balance. Adjust incrementally and test to find the best combination for your track.
