Monroe Max-Air MA705 Air Shock Absorber

The Monroe Max-Air Air Shock Absorber MA705 is built for rear suspension applications that need added support for towing and hauling. It can be inflated or deflated up to 150 PSI to help maintain ride height when extra weight is added, including loads up to 1,200 lbs. depending on the vehicle’s suspension, tires, and transmission.

Compatible with classic Ford Mustang, Mercury Cougar, Mercury Montego, and Ford Thunderbird rear suspension applications, this air shock is a practical choice for drivers who need adjustable load control without changing the vehicle’s basic suspension layout.

Key Features

  • Adjustable air pressure up to 150 PSI for load-leveling support
  • Rated for additional weight handling up to 1,200 lbs. based on vehicle limits
  • Rear air shock absorber for towing and hauling use
  • Rubber dust shield helps protect the shock shaft from road debris
  • Compressed and extended bumper stops are included in the shock design
  • Stem mount upper and lower mounting style with S4 mounting code
  • Monroe Max-Air product line for adjustable suspension support

Detailed Description

The Monroe Max-Air MA705 is an air shock absorber designed to help maintain a level stance when rear cargo, trailer tongue weight, or other added load affects suspension height. The shock features a 10.875-inch compressed length, 17.375-inch extended length, and 6.5-inch travel length, along with a rubber dust shield for added protection in everyday driving conditions. This part cross-references Monroe Shocks & Struts 49105 for the same application.

Use the MA705 on rear suspension applications for 1965-1973 Ford Mustang, 1967-1973 Mercury Cougar, 1968-1971 Mercury Montego, and 1961-1963 Ford Thunderbird. It is also listed for multiple Montego body styles, including sedan, coupe, hardtop, and convertible models. For fitment-specific air line routing, Monroe notes AK18 or AK64 air line kit usage depending on whether a single or separate left and right fill system is needed.

What It Helps Solve

  • Rear sag when towing or hauling
  • Loss of ride height after adding cargo weight
  • Need for adjustable rear suspension support
  • Uneven stance caused by load changes
  • Replacement needs for a rear air shock absorber on listed classic Ford and Mercury models

Installation Notes and Tips

Install this part in the rear position only on the listed applications. Verify stem mount dimensions, shock length, and suspension clearance before installation. Monroe specifies AK18 or AK64 air line kit usage for certain vehicles when replacing a single air shock fill system or when adding separate left and right air shock fill control. Follow the vehicle owner’s manual for load limits and suspension-related guidance.

Quality Assurance

Monroe manufactures the Max-Air line for adjustable load-leveling suspension service, and the MA705 is built to support the fitments and pressure range listed above. Confirm vehicle year, make, model, and rear suspension configuration before ordering.
