Secured to springs by U-bolts of heavy-duty construction. Attached
to axles are brake components and wheel assemblies.
6 Adjustable Radius Rods
Located roadside, Permit independent alinement of each axle.
Stabilize driving and braking forces.
Located curbside. Stabilize driving and braking forces.
7 Fixed Radius Rods
