Race Focused Outer Joint for Sakura Advance

The 3Racing SAK-U122A_HD Gear Differential Outer Joint is aimed at drivers who demand repeatable differential behaviour for tuning and lap consistency. Fitting cleanly to Sakura Advance components, it reduces slop and helps maintain intended gear mesh under load so steering response and traction remain stable during aggressive runs.

How does this joint influence differential tuning?

By tightening the outer link tolerances, the SAK-U122A_HD helps the diff behave more predictably, allowing finer adjustment of oil weight and preload for track conditions.

Is this suitable for track day upgrades?

Yes, it is intended as a direct-replacement upgrade to restore precision and durability which benefits repeatable lap times and consistent handling in race environments.

What maintenance should a racer plan?

Regular inspection, correct diff grease choice, and checking gear mesh are recommended to preserve performance; replace at first sign of excessive play.
