3Racing Sakura XI/Zero 4mm Rear Graphite Shock Tower SAK-X11/4/WO Technical Rear Tower  [SAK-X11/4/WO]

Rear Tower Upgrade for Precise Chassis Response

The 3Racing Sakura XI/Zero 4mm Rear Graphite Shock Tower SAK-X11/4/WO is engineered to increase rear section stiffness while keeping mass low. Its 4mm graphite construction offers a reliable mounting surface for shock assemblies and aides consistent chassis behaviour during aggressive driving.

Consistent Rigidity for Setup Repeatability

Fabricated from 4mm thick graphite, the tower reduces flex at the rear bulkhead and helps maintain consistent suspension geometry. This repeatability makes setup comparisons easier when testing spring rates or damping changes.

Accurate Fitment for Sakura XI and Zero Platforms

Designed to match factory mounting locations on Sakura XI and Zero models, the tower integrates without modification and preserves original shock alignment for straightforward installation.

Race-Oriented Upgrade for Tuning Focus

Intended for drivers who tune chassis balance, this rear graphite tower offers a stable platform that supports fine adjustments to rear traction and handling, helping to narrow the setup window at competitive events.
