Suspension Systems
The suspension systems incorporated into Dexter axles are
designed to provide the trailer owner three basic functions:
1. Attach the axle to the trailer
2. Dampen the effects of road shock
3. Cushion the cargo or load
All Dexter suspension systems are available in single and
multiple axle configurations. The three types most commonly
available are double eye leaf spring, slipper spring and Torflex®.
.
Double Eye Leaf Springs
Double eye springs have eyes formed in each end of the spring
with anti-friction bushings fitted for wear resistance. The springs
are held to the axle tube using a system of U-bolts and clamp
plates and are attached to the trailer as shown.

Articulation of this suspension occurs when the spring becomes
loaded and consequently lengthens. The double pivot action of
the shackle links accommodates this articulation and allows the
system to move freely.
In multiple axle installations, the action is the same with the
additional movement of the equalizer assembly. This serves to
transfer instantaneous loads from one axle to another in an effort
to “equalize” the load between the axles.
