STATEMENTS OF CONFORMITY
TABLE C
CG
hl
= Horizontal distance from front axle to cargo CG:
Model WB (in) CGhl (in)†
Regular Van 138 116
†Extended Van or Extended Wagon 138 126
†Cutaway (SRW) 138 121
(DRW) 138 127
†Comm. Cab/Box Partition (DRW) 158 134
†RV (DRW) 158 138
†Comm. No Partition (DRW) 158 143
†RV (DRW) 176 153
†Comm. (DRW) 176 160
† If CG
hI
is not given in the table or if the location of your cargo is
not in the normal cargo area, then your CGhI may be estimated
as the distance from the of the front wheel to the horizontal
midpoint of the cargo area.
TABLE F
CG
VC
= Vertical distance from ground to chassis CG
(Dimensions are inches)
E-150 & E-250 Van <8000 lb GVWR = 28.5
E-250/350 SRW Van or Wagon >8000 lb GVWR = 32.0
E-350 Cutaway = 28.0
E-450 Cutaway = 26.5
E-350/450 Basic (Stripped) Chassis = 26.5
TABLE E
CG
v
= Vertical distance from the ground to the completed vehicle center of gravity [inch].
GVWR <8000 lb Use Equations A & B, page 12
Place the CG
h
of the vehicle (from Equation B) into the appropriate equations below to determine the allowable range
of the CG
v
. If the actual CG
v
(from Equation A) is within the range calculated, the center of gravity location is acceptable.

GVWR > 8000 lb to <19000 lb Use Equations C & D, page 13
Place the CG
h
of the vehicle (from Equation D) into the appropriate equations below to determine the allowable range
of the CG
v
. If the actual CG
v
(from Equation C) is within the range calculated, the center of gravity location is acceptable.
Equation for CGv Range
Model WB Upper Limit Lower Limit
E-250 138 CGv = 1.27 x CGh - 59.0 1.27 x CGh - 77.5
E-350 (SRW) 138 CGv = 1.27 x CGh - 60.0 1.27 x CGh - 80.0

TABLE D
CG
hp
= Horizontal distance from front wheel to front
passenger load. (Dimensions are inches)
All E-Series† 48.5
† Except the E-Series Basic (Stripped) Chassis where the distance
from the of the front axle to the H point of the driver must be
measured.
