64-73 Shock, Rear, Monroe Max Air, set

These Monroe Max Air shock absorbers are ideal for vehicles that haul heavy loads or tow trailers. They are designed to maintain vehicle height and can be inflated or deflated as needed, from 20 psi to 150 psi with the vehicle loaded. If you're hauling a heavy load, try these Monroe Max Air shock absorbers to get the job done.

The Monroe Max Air shock absorbers feature the following:

* All-weather fluid that contains special modifiers to ensure smooth rod reaction
* Full displaced valving on both the compression and rebound for a comfortable ride
* Sintered iron piston that enhances durability for long service life
* Lubricated air sleeve that reduces friction and provides smoother operation during suspension movement
* Hardened and precision-ground 1/2 in. piston rod for consistent performance
* Large-volume air chamber that will hold a maximum of 150 psi

Capacity is limited by vehicle suspension, tires and transmission. See vehicle owner's manual for details.



Installing air shocks is a straight-forward job, but there are some things to keep in mind for a successful repair:

DON’T ROTATE
While most shocks can be rotated, air shocks can’t be twisted. The upper and lower part of the air shock has a fixed alignment due to the bellows. If the upper and lower mounts aren’t aligned in parallel, it won’t work properly. Don’t twist the upper or lower mount.

MOUNT AIR LINE FITTING PROPERLY
It is important to have the air line fitting on the dust shield facing in the proper direction. If it isn’t installed correctly, the air line may extend out and could rub against the tire. Be sure to affix the air line to the frame of the vehicle (and not the suspension) to allow for play. In some cases, you may have to strap the air line to the dust shield with a zip tie to hold it away from the tire and/or exhaust system.

AVOID TIRE WEAR & HANDLING ISSUES
Air shocks should be adjusted to maintain the original ride height. If the shocks are adjusted to make the ride height higher than what the manufacturer intended, it can affect the suspension geometry of the vehicle and can lead to excessive tire wear and handling issues.

INSTALLING AIR LINE FITTINGS
On most air line fittings, the O-ring is compressed around the air line. The proper procedure is to slide the nut and O-ring onto the air line and then insert it into the shock. This ensures the air line is inserted correctly in the fitting. The fitting may leak if you install the O-ring and nut onto the shock first.

WHERE TO MOUNT THE T-FITTING
Mount the T-fitting in the trunk or somewhere easy to access when you need to add air. If you install the T-fitting in the trunk or somewhere else inside the vehicle, make sure it won’t get damaged by anything you store there.

AVOID OVERTIGHTENING AIR FITTING NUT
Tighten the plastic nut on the fitting on the dust shield by hand. If you overtighten the fitting, it can pinch off the air line and air won’t get into the shock.

PUTTING AIR IN THE SYSTEM
Once the air shocks are installed, you’re ready to put air in the system. Keep in mind that air shocks are like tires: you shouldn’t operate the air shocks with no air in them. For a manual system, you should have a minimum of 20 PSI in the shocks. When under load, add only enough air pressure to maintain level ride height. More air isn’t better; it will change the ride height which will lead to ride harshness and damage to suspension parts.
