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

Single-piece brass mount tailored for MRX-5

The Arrowmax AM-MRX5-H0772-V3 is a V3 one-piece engine mount engineered for the Mugen MRX-5 chassis. Machined from solid brass, this replacement removes multi-piece join movement to give a firmer mounting interface between engine and chassis.

This V3 update adds two extra engine fastener points compared with the original design, increasing contact area to help keep alignment under load. The rear plate profile is also revised to match the new mounting geometry while preserving the standard MRX-5 engine fitment locations.

Installation notes: fit this part as a direct swap where the MRX-5 mounting footprint is used, reusing the chassis mounting hardware and engine bolts. Check alignment and torque during fitment to ensure the mount clamps evenly.

Tuning role: as a dense brass one-piece, the mount raises mass at the engine bay which can shift vibration and power delivery into the chassis. Racers often choose this component to secure the engine more rigidly for repeatable setup and trimming.

For MRX-5 builders wanting a heavier, single-piece brass mounting option, the AM-MRX5-H0772-V3 adds mounting points and a revised rear plate to help maintain engine seating and alignment during competitive setup.
