Yokomo Z2-S1S2A Front Shock Dampers  [Z2-S1S2A]

Front shock design briefing

The Yokomo Z2-S1S2A Front shock set (X33 type) is a front damping assembly that uses a threaded piston-shaft connection to fasten the piston to the shaft. It is engineered to prioritise a stiffer shaft and enhanced sealing to support consistent damping at the front of B-YZ2 series chassis.

Highlighted features include a 3.3mm rigid shock shaft and an X cross section O-ring which helps reduce friction while improving the seal. The threaded shaft arrangement secures the piston and reduces the chance of piston shift under load, aiding consistent damper performance during running.

Springs and shock oil are not part of the kit and must be sourced separately to complete each damper and achieve the desired ride height and damping. When assembling, ensure proper piston alignment and O-ring seating to prevent leaks, and select oil viscosity and spring rates suited to your setup.

Designed as a direct-replacement for the specified B-YZ2 models, this front shock set provides a firmer shaft and improved sealing; remember to fit appropriate springs and shock oil to complete setup and fine tune handling.
