Mugen MRX5 Shock Spring Support Set 7075-T6 AM-MRX5-H0555 by Arrowmax  [AM-MRX5-H0555]

Aftermarket spring supports for MRX5

This pack contains four shock spring supports produced as direct replacements for Mugen MRX5 shock assemblies. Turned from 7075-T6 aluminium and CNC milled, the retainers have non-essential material removed while leaving structural areas intact to reduce rotating and reciprocating mass without altering how they fit.

These retainers provide the lower seating for coil springs on MRX5 shocks, keeping springs located correctly and establishing a repeatable reference for preload and ride-height adjustments. The engineering prioritises consistent seating over decorative changes.

Fitting is easy: remove the OEM spring support from the MRX5 shock assembly and install the Arrowmax retainers in the same orientation. No modifications to the shock body are necessary and standard shock service tools are sufficient.

From a tuning perspective the component helps lock spring position during setup work so that small adjustments and spring swaps yield more repeatable results between runs.

A functional machined alternative to the stock MRX5 spring seats, intended to secure spring position and support consistent chassis setup when used on MRX5-spec shocks.
