GM called the devise a “ride stablizer” and it was regular equipment on all panel-body trucks (1/2 and 1 ton Panel, and Canopy Express, and 1/2 ton Surburban).
It was also standard equipment on the Forward Control Chassis models.
I think there were two styles between 47-55, with the bar diameters, rubber bushings, and maybe the bushing holders being different?
Jim Carter might still sell the bushings, and, maybe Steele Rubber sells them?
