HPI Baja BJ186f Steel Shock Shaft BJ186F/SH Replacement by GPM  [BJ186F/SH]

Aftermarket shaft for Baja BJ186f shocks

This steel shock shaft is intended for the HPI Baja BJ186f and supplied as model BJ186F/SH, offering a straightforward replacement for worn or bent stock rods in scale Baja shocks.

Service steps: open the shock body, remove the old shaft and internal parts, check the condition of seals and bearings, then fit the new steel shaft and reassemble using the oil viscosity and spacer configuration you prefer for your terrain.

The component keeps the piston and rod aligned, helps resist bending during hard off-road use, and gives a consistent sliding surface that reduces binding when you change valving or spacer stacks; it is an aftermarket part for suspension maintenance and tuning.
