This two-piece steel shaft set is supplied for replacement use within the Medius X26 steel EP SER400052 shock assembly. The shafts are meant to replace bent or worn components during scheduled shock maintenance on X26-type units.
The shafts occupy the internal shock bore where straightness and finish affect damping predictability. Replace them when rebuilding shocks, correcting bent parts, or preparing the model for fine tuning of suspension behaviour.
Standard fitment steps apply: disassemble the shock, remove the old shaft, inspect seals and bearings, fit the new shaft, ensure smooth piston travel, and reassemble with the correct shock oil for your tuning goals. This content refers specifically to RC-scale shock service workflows.
Supplied as a matched pair, these steel shafts provide a direct replacement option for Medius X26 style shock assemblies where steel shafts are specified, assisting consistent rebuilds and setup precision.
