Sturdy 5/8” diameter U-bolts secure the body to the frame, forward U-bolts are spring loaded to withstand movement of chassis frame
Double I-beams are reinforced with massive 2” x 4” extruded gussets
7/16” thick, 3” x 4” double I-beam cross members for extra support
Sub frame is welded to 3/4” thick extruded aluminum frame rails and isolated from chassis frame by 1/2” thick neoprene rubber extruded channel
Booster tank protection shield
Compartment framework made of 2” x 4” extrusions
Body Compartments are 5052 H-32 3/16” thick aluminum alloy plate and continuously welded for extra strength
Corners are made from 3.5” x 9.75” vertical extrusions with wall thickness of 1/4” for extra strength

The subframe, compartment framework, hose bed, wheel wells, beavertails, pump compartment and running board/tailboard assemblies all rely upon heavy duty extruded aluminum shapes that have a particular design function which give this body the superior strength need for any situation.
Ferrara’s extruded aluminum body features massive body corner extrusions, twin I-beam subframe with heavy duty gussets and extruded compartment and hose bed framework. This innovative design offers an unprecedented blend of durability and function.
