1949 3100 Advance-Design Suburban - 1/2 ton
An optional 10-leaf Heavy Duty Rear Spring set was available in 1954 (but is not listed in 1949). In 1954, the 10-leaf set was an RPO for the 8-leaf spring set that was standard from 47-55. 16" wheels were standard in all A-D years on Suburbans (15" wheels were optional).
The "anti-sway" bar (a better name) was called a "stabilizer" by GM and was standard on the Suburban and the 1/2 ton Panel (the stabilizer might not have been installed on the 1-ton panel, however). The style of this assembly changed in 1951. Jim Carter sells both styles of bushing sets.
Of course, someone might have installed helper springs.
