    The early trucks that had 8 lugs were 8600 GVW Both the K 2500 and the K 3500 as long as they were single rear wheel. The 6 lug 2500 was 7200 GVW

    According to this source: https://www.gmheritagecenter.com/do...its/Chevrolet-Trucks/1988-Chevrolet-Truck.pdf

    K2500 frames for regular cab and extended cab have a section modulus of 3.46 and 4.30, respectively (page 10)

    K3500 frames for regular cab and extended cab have a section modulus of 5.61 and 6.48, respectively (page 12)

    Section modulus is a measure of how stiff an element is. Assuming the same height for both frames, the K3500 will have to be heavier wall.

    On this reference, the C/K2500 are GVWR=7,200 lbs while C/K3500 SRW GVWR = 8,600 lbs

    However, on this other source (page 6,) K3500 and K2500/C6P both show GVWR = 8,600 lbs and rear axle capacities are shown identical. The non-C6P K2500 GVWR = 7,200 lbs.

    I'm not sure if there was a change from '88 to '89, nor what the C6P option was. I'm sure someone here will know.
