3Racing SAK-F31/4/WO Sakura FF Rear 4mm Graphite Shock Tower  [SAK-F31/4/WO]

Sakura FF rear upgrade with 3Racing SAK-F31/4/WO 4mm graphite

Fit the 3Racing 4mm rear graphite shock tower to stiffen your Sakura FF chassis and improve crash resilience. This precision part is aimed at hobbyists and club racers who want a stronger rear end without adding excess weight.

Engineered for consistent strength and low mass

The 3Racing 4mm rear shock tower uses dense graphite to deliver a balanced mix of stiffness and lightness. That combination reduces deformation under load and helps the car retain predictable behaviour during hard sessions.

Sharper handling through increased rear rigidity

Thicker material increases suspension mount stiffness, tightening rear-end response and improving rotation on entry. The upgrade helps drivers achieve more consistent cornering across a variety of on-road surfaces.

Straightforward fitment to Sakura FF chassis

Designed to match Sakura FF mounting points, this shock tower installs using your existing hardware for a clean swap. It is a practical upgrade for racers and experienced hobbyists refining their rear geometry.
