This Serpent 402169 set comes as two matched steeringblocks intended for maintenance and repair of Medius X26 RC assemblies. Compatibility is stated with the Medius X26 steel EP SER400052 chassis, and the dual-piece supply reflects the product listing.
Fitting these steeringblocks is a chassis-level procedure: detach wheel hubs and steering arms where necessary, swap in the replacement blocks, check associated pins and bearings for wear, then reassemble while confirming free movement and correct centring. Ensure there is adequate clearance through full suspension travel to avoid binding.
Because steeringblocks influence steering geometry and dynamic response, changing worn blocks can stabilise toe settings and reduce play. After replacement carry out alignment checks and make measured link adjustments to optimise handling.
