3Racing SAK-C139 - 5.2mm Titanium Suspension Pivot Ball - Precision Tuning Part  [SAK-C139]

Fine tune your Cero suspension with a titanium pivot

Engineered for hobbyists and racers, the 3Racing SAK-C139 - 5.2mm Titanium Suspension Pivot Ball brings tougher component life and cleaner joint movement to Cero chassis systems. The titanium construction keeps pivot action steady under repeated impacts and aggressive cornering, helping drivers hold consistent lines.

Material choice that balances weight and strength

Titanium offers high tensile strength while staying light, which is why the 3Racing SAK-C139 part is chosen for demanding setups. The material reduces the chance of deformation and preserves suspension geometry through hard sessions.

Exact 5.2mm fit for reliable installation

The 5.2mm sizing matches the Cero series mounting holes so the pivot ball seats correctly and cuts down unwanted movement in the linkage. That tighter fit improves steering feedback and helps maintain predictable handling under load.

Suitable upgrade for hobbyists focused on handling

For those working on handling balance and responsiveness, the 3Racing SAK-C139 pivot ball makes small but meaningful gains in suspension articulation. It is a practical upgrade for drivers refining camber, toe and roll response on track.
