I'm wondering if the 9,990, 11,030, and 12,125 GVWR versions all use the same chassis (to include the same brakes and rear drive axle assembly).

Are the only differences in the spring rates?

The 9,900 is a SuperSingle not a dually isn't it.

The 9,900 is a SuperSingle not a dually isn't it.

The 8,550 and 9,050 GVWR versions are available only with single rear wheels.

The 9,990 and 11,030 GVWR versions come standard with dual rear wheels. The "Super Singles" are available as an option.

The 12,125 GVWR is available only with dual rear wheels.

Well, the 12,125 GVWR 4500 comes only with a 65 mph electronic speed limiter...

I have the heavy version over here 5000kg and my vin decoded has these factory extras that my friends doesn't
Option C43 - REAR-AXLE STABILIZER REINFORCED LOWER FRAME
Option C45 - H.D. FRONT AXLE STABILIZER
And this bit is different :-
Rear axle 1:
741414 -G 346749
Major assembly variant: X 004 070 399
Part var. design.: 7414220
AXLE RATIO I = 4.727
Hope it helps, copy and paste is a pain in the arse on an Android tablet!

Is that a Cargo Van, a Crew Van, Passenger Van, or Cab Chassis?

I'm not seeing the 4.727 rear axle ratio listed as standard or optional for any version of the 4500. Just the standard AR3 4.182 and the optional AR2 3.923.

Thanks.

I guess your market gets the 4.727 rear gears, and our market doesn't.
