MUGEN MRX5 Hardened 7075 Spring Cup by Arrowmax - AM-MRX5-H0753  [AM-MRX5-H0753]

Durable spring seat for MRX5 shocks

The Arrowmax AM-MRX5-H0753 spring cup is produced from 7075 aluminium as a replacement spring seat for the Mugen MRX5 shock assembly. It is intended to be used at either end of the damper to form a robust interface between the coil spring and the shock body.

When setting up the suspension the cup helps retain consistent spring position, reduces deformation under load and enables repeatable preload adjustments so comparisons between setups remain valid. The hardened alloy concentrates wear resistance where the spring contacts the shock.

Installation on compatible MRX5 shocks is simple: remove the original cup, fit the Arrowmax cup ensuring the spring seats evenly, then rebuild the shock checking for free shaft movement and no binding. Always verify clearance with the spring retainer and adjacent parts prior to refitting on the model.
