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

Shock spring support for MRX5

This set of shock spring supports is produced as a direct replacement for Mugen MRX5 shock assemblies, supplied as four pcs per pack. Machined from 7075-T6 aluminium, the retainers are milled to remove excess material while keeping structural areas intact, reducing rotating and reciprocating mass on the shock shaft without altering fitment.

Functionally these parts act as the lower seating for coil springs on MRX5 shocks, holding the spring in position and providing a repeatable datum for preload and ride-height adjustments. The design focuses on consistent contact and concentric seating rather than decorative changes.

Installation is straightforward: remove the original spring support from the MRX5 shock assembly and fit the Arrowmax retainers in the same orientation as the factory parts. No additional tools beyond typical shock disassembly tools are required, and no modifications to the shock body are necessary when used on MRX5-spec shocks.

In tuning terms the component helps maintain consistent spring location during testing and setup, which can make small differences in repeatability between runs when adjusting spring preload or swap-outs during chassis setup.

A practical, machined replacement for MRX5 spring seats intended to provide stable spring positioning and consistent setup results when used with standard MRX5 shock assemblies.
