GF01 Replacement King Pin Set 5mmx6.2mmXM4 - GF004S by GPM  [GF004S]

Steel king pins for GF01-derived chassis

This is a steel king pin replacement kit for Tamiya GF01-derived chassis, shipped as four pieces. The components are intended to replace original-style king pins in steering knuckles and suspension link joints on scale RC vehicles.

Use these steel pins when original pins show wear or when a more rigid steel option is required during maintenance. Installation normally requires removing the knuckle or link, pressing out the worn pin and installing the new one; confirm thread engagement and secure with the matching M4 fastener as per the original build. Swapping to steel pins will affect steering response and long-term wear characteristics, so check related parts after fitting.
