Description
The Meritor RideSentry™ MPA Series sliding tandem trailer air
suspension system centers around a stabilized parallelogram design
that incorporates a single unified frame bracket. The upper and

directly over the axle. Figure 2.1.
Ride height and mounting height are important measurements for
overall vehicle height. Measure ride height from the centerline of the
axle to the bottom of the slider frame. Measure mounting height
from the centerline of the axle to the bottom of the trailer frame.
