Race-focused 3Racing F113-303 titanium coated king pin shaft

The 3Racing F113-303 King Pin Shaft uses a titanium coating to raise surface hardness and lower friction at the steering pivot. At 3.17 x 31.8mm, the shaft matches F113 chassis tolerances and is intended for tuners seeking reliable pivot performance under competitive conditions.

Material and tuning benefits

The titanium finish provides improved wear resistance and maintains smoother input transfer during extended running. Reduced friction helps preserve steering geometry consistency, a key factor when refining race setups and steering response.

Installation and setup considerations

Install the 3Racing F113-303 as a direct replacement in F113 assemblies. Check knuckle bore alignment and endplay during fitting to ensure optimal preload and to avoid introducing unwanted steering bind. Pairing with fresh bushings or bearings will maximise handling gains.

What tolerance checks should I perform after fitting?

Verify lateral play and rotation smoothness in the knuckle. Ensure endplay is minimal but not zero to avoid binding during suspension travel.

Is the part suited to high grip tracks?

Yes. The hardened surface helps resist accelerated wear common on high grip surfaces, preserving steering feel across race trims.

Any advice for race day maintenance?

Carry a spare shaft and inspect the coating and bores between heats. Replace if you see scoring that could affect steering precision.
