HPI Racing SAVAGE XL FLUX C Hub and Knuckle King Pin Screw Set SAVF004S by GPM  [SAVF004S]

Reduce hub play with stainless king pins

This four piece stainless king pin screw set is intended for the HPI Racing SAVAGE XL FLUX to secure front C hubs and rear knuckles and reduce unwanted movement. Tightening the hub connection results in a more precise steering feel and improved consistency under braking and cornering loads.

Fit and install notes: screws feature M4 threads and are tightened using a 2.5mm hex driver. The unthreaded section of the king pin has a diameter of 3.98mm and an overall length of 21mm, matching the original mounting form factor for the hub and knuckle. Use correct engagement length and a suitable RC threadlocker where needed.

Tuning context: fitting these stainless pins can lower joint flex and gap, aiding steering accuracy especially when experimenting with stiffer springs or stronger steering setups. These components are designed for model use on the specified chassis only.
