Mugen MRX-5 Pivotball Suspension (Titanium) by Arrowmax AM-MRX5-D0105R-1  [AM-MRX5-D0105R-1]

Pivotball suspension for MRX-5

This is a pair of pivotball suspension parts designed for the Mugen MRX-5 chassis as an RC-scale upgrade component. Machined from titanium using CNC processes, the parts trade mass for strength at the vehicle extremities to lower rotational inertia without compromising structural durability.

Fitment and role — these pivotballs replace plastic or steel stock items on the MRX-5 suspension linkage points to change the mass distribution at the wheel ends. That shift helps the suspension react faster and gives finer control when dialling in roll and transient response during setup.

Installation notes — the pieces fit the MRX-5 hardware locations and use the same mounting approach as the original pivotballs; inspect thread surfaces and mating parts for correct engagement and use appropriate fastener torque values recommended for your chassis hardware. Regular inspection is advised when used in high-load track conditions.

Use these titanium pivotballs when you want reduced mass at suspension extremities to refine steering feel and suspension response on the MRX-5, while retaining a durable metal connection at critical linkage points.
