Product Details

What It Helps Address

• Uneven ride height after loading the vehicle
• Loss of suspension support under added weight
• Need for adjustable rear shock pressure
• Replacement of worn rear air shock absorbers on listed Dodge and Plymouth applications

Installation Notes and Tips

Use the correct air line kit for the vehicle setup; the fitment notes call for AK18 or AK64 Air Line Kit depending on the application and whether a single or separate left and right fill system is used. Review the vehicle owner’s manual before setting pressure, and confirm suspension, tire, and transmission limits before adding load. Verify upper and lower mount codes LS38 and LS39, along with compressed and extended length measurements, before installation on your Dodge Ram 1500 Van, Dodge Ram 2500 Van, or other listed rear applications.

Quality Assurance

Monroe engineers the Max-Air line for adjustable load support in rear suspension service. MA746 is built with a dust shield and bumper stop features to support everyday use in towing and hauling applications across the listed Dodge and Plymouth fitments.
