Medius X26 Rear Lower Wishbone Arm (Steel) - 402172 Serpent  [SER402172]

Medius X26 rear wishbone — use and setup notes

The Serpent 402172 rear lower wishbone is supplied as a steel replacement part for the Medius X26 steel EP chassis family identified by SER400052. It is intended to be fitted in the rear suspension using the original attachment points so the Medius X26 geometry is retained.

Being steel, the arm provides structural strength between the hub carrier and lower suspension elements. Correct alignment of ball studs and pivot locations is essential to maintain the original roll center and suspension kinematics.

For installation, check thread engagement on every fastener and use threadlocker where the chassis setup calls for it; torque bolts to the figures in Medius X26 maintenance documentation. After installation, perform a static suspension inspection and a short functional test to confirm freedom of movement and absence of play.

Tuning perspective: swapping to a steel lower wishbone will modify lateral stiffness and feedback. Use this component to preserve factory geometry or to intentionally adjust handling and durability for specific running conditions.

Install the Serpent 402172 lower wishbone to keep correct rear suspension geometry on Medius X26 steel EP chassis and carry out routine checks after fitting to ensure predictable handling.
