i have two non dually (single rear wheel) 1 Ton trucks that are both GVWR 8800 lb 1953 Chevy 1 Ton (1434 - means it has a pick up box, cannot have duals on back, yet 8800 lb) 1953 GMC 1 Ton (9430 - delivered with platform, same axles as the pickup, 17inch rims front and back) both trucks have the overload auxiliary springs on the back
my daily driver 1950 Chevy 1 Ton is GVWR 6600 lb, it also has the auxiliary springs on the back, same spring stack up as the other two from 53.
my theory's as to why identical frames and suspension have such a different ratings are: 1 - each year GM got the GVWR moved up a tiny amount with either testing data or pure government lobbying 2 - the rules changed in their favor without trying 3 - they would have been able to list the GVWR at 8800 in 1950 but just chose not to being conservative 4 - the chassis and springs are actually different and i just can't see it 5 - i'm being gaslighted or off my medication and it has nothing to do with reality
if anyone knows the reason why GVWR changes in these year ranges for seemingly identical chassis and suspension layouts please chime in
all my trucks are Canadian models the GMC frame, suspension and axles are identical to the Chevy for Canadian trucks, the GMC uses the Chevy engine, the differences are the grill and hood and badging only (and the GMC radiator behind the grill). -s
