The four titanium king pin screws in this set are intended specifically for the Associated RC18T C-hub assemblies to retain the steering pivot and preserve C-hub geometry under repeated cycles of use.
These fasteners are designed as a lightweight, corrosion-resistant alternative to standard steel hardware for 1/18 scale on-road applications. When replacing king pins, inspect the mating C-hub and pivot surfaces for wear and ensure proper thread engagement to prevent damage.
Install the screws by hand-starting threads, torqueing to a conservative setting to avoid stripping, and verifying unhindered steering rotation after final fitment. The parts are provided for maintenance and durability enhancement rather than for modifying suspension kinematics.
