Reliable Engine Fixing for Mugen MRX5 with Arrowmax MRX5-H0704

The Arrowmax MRX5-H0704 Engine Nut is made to match the Mugen MRX5 chassis and deliver a secure engine hold. Constructed from spring steel, it offers a balance of strength and flexibility to resist loosening under load. Suitable for championship preparation or everyday hobby use where a steady engine mount is important.

Is this part a direct replacement for the stock nut?

The MRX5-H0704 is intended as a direct-fit replacement for the Mugen MRX5 mounting setup. Confirm thread size and seating face match your chassis before swapping.

How often should I inspect the engine nut?

Check the nut during routine maintenance and after heavy runs. Look for thread wear, any flattening of the seating face, or signs of corrosion.

Will this improve engine retention during hard acceleration?

A correctly installed Arrowmax MRX5-H0704 helps maintain engine position better than worn or loose original nuts, reducing movement under hard acceleration.

Any recommended care to prolong service life?

Keep the nut clean and dry, remove grime after runs, and replace if you spot thread damage. A light protective coating can help prevent rust.
