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

King pin upgrade for firmer steering feel

This four piece stainless steel king pin screw set is made for the HPI Racing SAVAGE XL FLUX and secures front C hubs and rear knuckles to minimise play. The stronger connection helps deliver a more predictable steering response during rough or high load driving.

Fitment details: the screws feature M4 thread and are installed with a 2.5mm hex driver. The unthreaded king pin shaft measures 3.98mm in diameter with an overall length of 21mm, matching the original mounting geometry for the C hub and knuckle. Ensure correct thread engagement and use standard RC threadlock where appropriate.

Tuning notes: swapping to these stainless pins reduces joint gap and flex, useful when fine tuning steering behaviour or when using stiffer suspension settings. These components are intended for model use on the stated chassis only.
