Yokomo Z2-S1S2A X33 Front Shock Kit  [Z2-S1S2A]

Front shock construction details

The Yokomo Z2-S1S2A Front shock set (X33 type) is a front damping component for RC use that features a threaded piston-to-shaft fastening method. The design focuses on increasing shaft rigidity and improving seal integrity to keep front damping reliable across B-YZ2 series chassis.

Key parts include a 3.3mm rigid shock shaft and an X cross section O-ring that aim to lower shaft friction while delivering stronger sealing. The threaded connection secures the piston to the shaft, reducing piston movement under load and helping the dampers retain consistent behavior in both practice and competition.

Springs and shock oil are not supplied with this kit and must be purchased separately to complete the dampers and tune performance. During installation, check piston centering and O-ring placement to prevent leaks, and choose shock oil and springs matching your setup goals.

As a direct-replacement option for the listed B-YZ2 models, this front shock set provides a stiffer shaft and enhanced sealing; source the appropriate springs and shock oil to tune the dampers to your handling preferences.
