YD-4 Rear Shock Tower for Tuning - Yokomo Y4-018  [Y4-018]

Rear shock tower to tune rear stiffness on YD-4

Designed for the YD-4 chassis, this rear shock tower uses a 4mm graphite plate to create a firmer attachment for the rear shocks. The increased stiffness helps maintain consistent shock travel and alters the rear end feel without modifying internal damper internals.

Compatibility is limited to the stated chassis: YD-4 and DP-YD4MR. As an aftermarket tuning item the tower changes how the rear bulkhead transfers loads into the suspension and can be used to fine tune balance and traction.

Fitting is straightforward on standard YD-4 rear assemblies: remove the original tower, move over any hardware and shock mounts, then install the Y4-018 in the original mounting points. Verify threads and mating surfaces so the tower sits true and fasteners torque correctly.
