Rear Suspension '51 - 3/4 ton

[mgeez]

Is the upper set of rear springs called an "auxilliary spring set"? I am trying to figure out if this upper set of springs is part of what makes the rear suspension a 3/4 ton truck. Do 1/2 tons have this upper set? I will never load anything other than a cooler in the bed and was wondering if i would get into any problems removing this upper set. Some advantages I might have would be 1) a more "clean" look in that area, 2) a softer ride, and 3) it may lower the rear a bit. If I can remove the upper set, I figure i will need new U-bolts since there appears to not be enuf threads on the bolt itself if i remove the upper set. Any help would be appreciated.
