Precision steel king pin for GF01 series

This aftermarket king pin is engineered as a direct-fit steel replacement for Tamiya GF01-family steering pivots on 1/10 scale RC models. The set comprises 4pcs in the specified 5mmx6.2mm XM4 dimension to re-establish accurate pivot geometry where original components have degraded.

Application: the pins locate at the steering knuckle and suspension pivot interface on compatible Tamiya chassis, providing a hard-wearing contact surface to reduce play under load. Proper installation includes verifying bore concentricity and ensuring full seating to maintain alignment and steering precision.

Service recommendations: inspect knuckle bores and bearing faces for wear prior to reuse, confirm smooth rotation and freedom from binding after installation, and replace any companion fasteners or inserts showing thread wear. These items are intended for model repair and performance upgrades.

What inspection steps ensure correct fitment?

Measure knuckle bore diameter and check for ovaling, confirm bearing faces are flat, and clean mating surfaces. Use a press or controlled drift to seat the pin squarely without inducing preload.

Are torque values affected by using steel pins?

Steel pins increase local hardness; use standard fastener torque for the chassis but inspect threads and inserts and avoid overtightening which can distort softer housings.

What maintenance gives longest service life?

Regularly clean and inspect bore and bearing interfaces, protect exposed steel from corrosion, and replace companion hardware showing wear to preserve alignment and function.
