Fine-Tune Your YZ-4S Suspension

The Yokomo S4-300BSA Suspension Mount Bushing is aimed at hobbyists who want tighter control over suspension geometry on the YZ-4S chassis. Made to pair with aluminium suspension mounts, this resin bushing provides precise relocation of the suspension arm pin. Changing the installation direction or frame mounting can help you adjust toe and roll characteristics for your preferred handling.

Models That Work with This Bushing

This bushing is compatible with a wide range of Yokomo models, including the B-YZ4SF, B-YZ2DTMW, B-YZ2DTM2, B-YZ2CAL2, B-YZ2T, and B-YZ2DTM2S. That makes it handy for workshops that service multiple Yokomo cars.
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.

Is the S4-300BSA suitable for tight corner tracks?

Yes, adjusting the arm pin position with this bushing lets you tune the suspension response for tighter cornering, but always pair changes with shock and tyre setup for balance.

Do I need special tools to install it?

Installation is straightforward with basic hobby tools. A small press or careful hand-fitting will locate the bushing; ensure it sits flush and the pin moves freely without binding.

Can I use the same bushing on multiple Yokomo cars?

Yes, the bushing is compatible across several Yokomo models listed above, so you can swap it between cars that share the same mount geometry.

How does installation direction change handling?

Reversing or rotating the bushing shifts the pin axis and can change roll centre and steering feel. Make one change at a time and record results to find your preferred setup.
