'67 Heavy Duty Rear Coil option
The guy I got my truck from many years ago referred to it as a "heavy half-ton" The option sheet indeed lists it as having a heavy duty spring. Is this common? Rare? It is a half-ton with 6 lug wheels and coils at all four corners.

Re: '67 Heavy Duty Rear Coil option
I have not seen this option before but I assume it is merely a higher rate coil spring maybe closer to a 3/4 ton spring rate.

Re: '67 Heavy Duty Rear Coil option
Is it a helper spring? I have seen some that look like a half of a leaf that clamps onto the frame behind the axle?

Re: '67 Heavy Duty Rear Coil option
I have seen the helper spring but I think the option sheet (SPID) lists it as "G60 auxiliary rear springs". The G50 option, as in this case, is just a heavier rate coil spring.

Re: '67 Heavy Duty Rear Coil option
I'll have to look at my 67 Panel's option sheet. I think it listed heavy rear springs, and it had the "helper" spring attached to the frame, which would rest on the top of the axle under a load.

Re: '67 Heavy Duty Rear Coil option
mclairmo is right. G50 heavy rear spring is just a higher rate coil spring. My panel had the G60 "auxilliary rear springs" option, which was the helper leaves. My bad.

Re: '67 Heavy Duty Rear Coil option
The rear coil springs on my '71 lwb stepper has the heavy duty option and no helper leaf springs.
It came with a 350 and compound 4 speed. Danny

Re: '67 Heavy Duty Rear Coil option
it is a 3/4 ton spring from the factory.
Does not make it a 3/4 ton truck though, still a lame rear end. the PO was wrong on calling it a heavy half. That was an option package in the late 70's. |
