Race oriented differential upgrade for Sakura FF

The 3Racing 18T Metal Differential Gear Set is intended for racers who need predictable drivetrain response. Built to suit the SAK-F79 chassis, this unit focuses on stable mesh and repeatable engagement under lap after lap conditions. Use it to reduce component variability and support consistent setup work.

Technical highlights for setup and tuning

The SAK-F79B metal set offers improved wear resistance compared with standard materials, helping to keep gear geometry consistent for tuning work. The 18-tooth ratio is selected to provide a balanced transfer profile that responds well to fine tuning of diff oil and suspension settings.

What should I check during installation?

Verify gear mesh and bearing play, ensure diff housing alignment is correct, and confirm the SAK-F79 mounting points match before final assembly.

How does diff oil choice interact with this metal set?

Diff oil viscosity still governs slip and lock characteristics; using heavier oils will increase resistance while lighter oils allow freer action. Tune oil to match track conditions and handling goals.

Are there recommended complementary upgrades?

Consider matching the diff upgrade with quality bearings and a secure motor mount to ensure the rest of the driveline supports the increased durability of the metal gears.
