Medius X26 steel EP Antiroll Bar Insert Set (4 pcs) for Medius X26 steel EP (SER400052) - Serpent 402176  [SER402176]

Adjustable antiroll inserts for X26

This Serpent 402176 antiroll bar insert set is an RC spare designed to let drivers tweak roll resistance on compatible X26 layouts. Supplied as 4 pcs, the inserts change the effective stiffness and response of the antiroll bar without replacing the entire bar assembly, enabling small, track-side adjustments to roll behaviour.

Compatibility in the original product notes points to Medius X26 steel EP (SER400052); confirm that chassis code when ordering. The inserts act as replaceable contact points inside the antiroll bar linkage or ends, allowing you to alter lateral compliance and transient roll to balance front and rear handling.

Fitting is straightforward for those used to touring car antiroll setups: remove the end links or bar retainers, swap the factory inserts with the new pieces, then reassemble and bench-test before hitting the track. No special tools beyond basic hex drivers are normally needed, but always follow your chassis maintenance routines and recheck fastener torque after refit.

Tuning tip: use these inserts for fine, repeatable changes to roll rate rather than making big jumps. Combine insert swaps with swaybar thickness and shock adjustments to refine understeer or oversteer; keep a setup log so you can revert or iterate methodically.

For hobbyists running Medius X26 steel EP platforms, these inserts offer a quick way to refine roll characteristics with minimal parts replacement and fast swaps between sessions.
