HPI Racing SAVAGE XL FLUX Aftermarket King Pin Screws Front C Hub Rear Knuckles SAVF004S by GPM  [SAVF004S]

Upgrade king pins for consistent steering

This set of four stainless steel king pin screws is built for the HPI Racing SAVAGE XL FLUX to secure the front C hubs and rear knuckles. By reducing the gap and unwanted movement at the hub joint, these pins help produce steadier steering inputs and repeatable wheel angles under load.

Installation and fit notes: each screw uses M4 thread and is tightened with a 2.5mm hex driver. The king pin shaft is unthreaded for the body, measuring 3.98mm in diameter with a total length of 21mm to match the C hub and knuckle mounting points. Use correct thread engagement and apply standard RC threadlock if required.

Tuning benefits: replacing softer or worn stock fasteners with these stainless pins reduces flex and gap, which assists when fine tuning steering characteristics or running more aggressive suspension settings. These parts are for model use on the listed chassis only.
