3Racing F113-303 Titanium King Pin Shaft Track Upgrade  [F113-303]

High wear resistance king pin shaft by 3Racing F113-303

The 3Racing F113-303 Titanium Coated King Pin Shaft is intended to boost the longevity of the steering pivot while keeping smooth operation. The shaft is finished with titanium coating, sized at 3.17 x 31.8mm, and designed to fit the F113 chassis form factor.

Advantages of the titanium surface

Titanium coating lowers abrasive wear and decreases friction at the pivot, which helps maintain predictable steering over many running sessions. The harder surface is less prone to scoring and maintains response under continued use.

Fitment guidance

Made for direct use with the F113 chassis, the 3Racing F113-303 installs without chassis machining. Its precise 3.17 x 31.8mm measurements keep alignment accurate and reduce the need for extra setup adjustments.
