The center of gravity of the completed
vehicle with a full load should not exceed
63 inches above ground level for the
16,000 lbs. GVWR, and must be located
horizon- tally between the centerlines of
the front and rear axles.
Figure 15.11.1
NOTE: The Final Manufacturer must ensure that the combined vertical center of gravity of the chassis, body, and available payload at full GVW does not exceed
the maximum vertical center of gravity outlined in the Isuzu Incomplete Vehicle Document and the Isuzu Body Builders Guide.
The maximum dimensions for a body installed on the N Series chassis are 102 inches wide (outside*) by 91 inches high (inside). Any larger body applications
must be approved by Isuzu Commercial Trucks of America (ICTA) Application Engineering.
On the West Coast call 1-562-310-8599 and on the East Coast call 1-770-740-1620 x4491.
