4mm graphite rear shock tower tailored to YD-4

This rear tower is built for the YD-4 platform and uses a 4mm graphite plate to provide a firmer mounting surface for the rear shocks. The stiffer mounting point helps reduce uncontrolled flex and keeps shock movement more repeatable under load.

Compatibility is limited to the stated chassis: YD-4 and DP-YD4MR. As a tuning component the tower modifies rear bulkhead stiffness and the suspension response to driver inputs and surface conditions.

Installation follows the usual YD-4 rear end procedure: remove the OEM tower, move existing hardware and shock mounts across, and secure the Y4-018 in the same holes. Inspect threads and contact surfaces so the tower sits flush and fasteners tighten without binding.
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 the graphite plate affect long term durability?

The 4mm graphite offers increased stiffness which can reduce stress concentration on flexible areas, often improving consistency over repeated runs when fitted correctly.

Will the tower protect against chassis flex damage?

It helps control flex at the rear bulkhead but is not a guaranteed protection against all impacts. Proper installation and inspection are recommended after heavy use.

Any maintenance tips to prolong life?

Regularly check fastener torque and mating faces for wear or deformation and replace any worn screws to maintain a flat, secure mount.
