Mugen MRX-5 Engine Mount Upgrade Brass One-piece - Arrowmax AM-MRX5-H0772-V3  [AM-MRX5-H0772-V3]

Brass one-piece engine mount made for MRX-5

The Arrowmax AM-MRX5-H0772-V3 presents a V3 one-piece engine mount developed for the Mugen MRX-5 chassis. Turned from a single block of brass, the mount replaces multi-part assemblies to reduce slop at the engine mounting interface.

This V3 variant adds two more engine fastening points compared to the previous release, increasing contact and helping to preserve alignment under load. The rear plate end has also been cosmetically refined to suit the updated mounting geometry while retaining MRX-5 positional compatibility.

Fitting notes: intended as a direct substitute for MRX-5 layouts that share the same engine footprint, it uses the standard chassis mounting hardware and engine fasteners. Confirm alignment and torque as part of normal installation routines to ensure even clamp across the mount.

Tuning considerations: as a solid brass component, the mount increases mass at the engine bay and can alter vibration behaviour and power transfer into the chassis. Many competitors fit this style of mount to secure engine position more tightly for repeatable setup work.

For MRX-5 competitors after a heavier, single-piece brass mounting option, the AM-MRX5-H0772-V3 introduces extra fixings and a reprofiled rear plate to enhance engine seating and alignment for race-day tuning.
