This graphite rear shock tower is an RC-scale component intended for use with the YZ-4 family. Constructed from 4mm graphite, the part lowers mass at high points of the chassis and helps reduce excessive roll during cornering, contributing to more predictable handling in 4WD off-road sessions.
Beyond mass placement, the tower increases the mounting rigidity for the rear shocks so impacts from rough surfaces are better absorbed by the suspension assembly rather than the mount. The result is a steadier chassis response when negotiating changes in track surface or direction.
For tuning, this tower is relevant when you want to influence roll characteristics and rear-end responsiveness without changing spring rates or damping; it changes how weight and shock loads are distributed rather than altering the shock internals.
