Medius X26 Compatible Rear Lower Suspension Arm 402172 - Serpent  [SER402172]

Steel rear lower arm for Medius X26 applications

The Serpent 402172 wishbone is a steel rear lower arm made for the Medius X26 steel EP chassis family identified by SER400052. It serves as a replacement component for the rear suspension assembly while maintaining the stock mounting points and geometry of the Medius X26 platform.

As a steel component, the arm provides a robust connection between the hub carrier and the lower suspension members. When fitting, ensure ball stud alignment and correct pivot positioning to keep suspension kinematics and roll center consistent.

Installation guidance: confirm thread engagement on all fixings, apply threadlocker if the chassis setup requires it, and torque fasteners to the figures in the Medius X26 service documentation. Conduct a static suspension check and a short dynamic test after installation to confirm proper operation.

Tuning note: choosing a steel lower wishbone will affect lateral stiffness and longevity; this is a practical option for drivers seeking greater resistance to wear under demanding use.

Use Serpent 402172 when a durable steel replacement is required for the Medius X26 steel EP chassis and follow post-fit checks to ensure consistent suspension performance.
