Graphite rear shock tower compatible with YZ-4S and B-YZ4SF

The S4-018A is a 4mm graphite rear shock tower built for 1/10 scale YZ-4 series touring car chassis. It replaces the stock rear shock mount plate and helps control rear roll stiffness and camber response.

Fitment covers chassis codes including B-YZ4SF and YZ-4S. During replacement, verify the mounting hole pattern against your existing shock posts and reuse the original six-point fasteners where possible to maintain the factory suspension geometry.

Specifications

  • Item Rear shock tower
  • Material Graphite, 4mm thickness
  • Model Number S4-018A
  • Compatibility B-YZ4SF, YZ-4S

Use this 4mm graphite tower to adjust rear roll characteristics and add alternative shock mounting positions during chassis setup and suspension tuning for 1/10 scale touring RC 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.

Will the S4-018A fit both YZ-4S and B-YZ4SF chassis?

The S4-018A lists compatibility with B-YZ4SF and YZ-4S. Confirm your chassis code before ordering to ensure correct fitment.

What is the material and thickness of this tower?

This rear tower is manufactured from graphite and is 4mm thick, chosen to influence torsional stiffness at the rear of the chassis.

Any installation tips to keep original geometry?

Align the tower hole pattern with your existing shock mount posts and where possible reuse the original six-point hardware to preserve the suspension geometry.

How will changing the tower affect handling?

A stiffer or thicker tower reduces rear flex, which can tighten corner entry and alter roll and camber behavior; use it as part of a broader suspension tuning plan.
