GPM TRX4004S Stainless King Pins for TRAXXAS TRX4  [TRX4004S]

Technical note on TRX4 king pin upgrade

The GPM TRX4004S stainless steel king pins are designed to improve front knuckle alignment and reduce rotational friction in the TRAXXAS TRX4 front assembly. By tightening the interface with C hubs the pins reduce axial and lateral play, resulting in more precise steering feedback and better repeatability under load. These corrosion resistant pins are intended for use with both stock and modified C hubs; installers should verify fit and apply appropriate lubrication during assembly to maintain smooth operation and longevity.
