Tamiya M03/M03L/M04M/FF02 64 Titanium King Pin by 3Racing M04M-01  [M04M-01]

Titanium king pin for Tamiya chassis

This is an RC-scale titanium king pin designed for use with Tamiya M03, M03L, M04M and FF02 on-road chassis. As a direct-replacement steering pivot, the part focuses on improved wear resistance and consistent steering geometry over time while staying within model-grade component standards.

The king pin's role is purely in the front steering assembly where it locates the upright and connects to the suspension geometry. When replacing the stock pin, inspect the upright and stub axle for freeness and correct clearance, keep existing washers and bearings in their original order, and verify there is no binding through the full steering throw. Use the chassis' original fasteners unless the kit specifies otherwise.

In tuning terms, a titanium king pin is a maintenance and longevity upgrade rather than a major handling modifier. It helps preserve alignment and reduces wear-related slop, which can support more consistent steering feel when you adjust toe, caster, or steering ratio on M03/M03L/M04M/FF02 based setups.
