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
congurations. The three types most commonly available are double eye leaf
spring, slipper spring, and Torex
®
.
Double Eye Leaf Springs
Double eye springs have eyes formed in each end of the spring with anti-friction
bushings tted for wear resistance. The springs are held to the axle tube using a
system of U-bolts and tie plates and are attached to the trailer as shown.

Shackle Link
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.
