What capacity truck is this?

[86chevytrk]

So, I’m going to buy a “new” truck soon but I can’t understand what size it is (tonnage). Can someone help explain the gvwr for me? It says gvwr 8600. And the gawr rr 6000. The seller doesn’t know either. Please help when you have time TIA.

That is a 3/4 t

It sounds like its the heavy duty 3/4 ton, which was rated by GM at 8600 GVW so that it did not require catalytic converters. 

In the first few years of emissions control you only needed a GVW of about 6250 lbs to be exempt from catalytic converters, which was why Ford had the F150 and GM had the Heavy-Half with higher 1/2 ton GVW ratings so that they were non-catalyst.  Then the government changed the non-catalyst requirement to 8600 GVW, so all were 3/4 ton or higher.

Based on weighing my 8400 GVW 3/4 ton truck, if I have two people in the cab and full gas tanks, I can carry a load of about 2700 lbs in the bed and will be right at 8400 lbs. Mine is a factory Camper Special, so I believe it has the highest GVW rated springs for a 3/4 ton.

Also, if it has 6 lugs on the wheels vs. 5 lug then it's most likely a 3/4 ton?

check the VIN number and don't guess. 5 lug is 1/2 ton C10/C15, 2wd K5, 6 lug is half ton K10/K15, K5 4x4.

Mine has 8 lug. 1GCGCG24M1FJ172216. But it's a single rear wheel

You have the heaviest weight 3/4 ton there is, G being the forth digit 8001-9000 lb brake system.  You should have the 14 bolt full float rear end with a 5.7L 350 engine
