G 50 spring option 1976

My '76 C 20 has it's original 56" G 50 HD rear springs and 1 of them is broken, so I'm replacing both. Any idea as to what lb spring the G50 option was? I'm looking at General Springs and they have several options available. I only use the truck to pull a loaded 22' car trailer with a 7,000 lb GVWR.

Re: G 50 spring option 1976

how many leafs in the pack ? and the overload on the bottom is a given .

7+1 or 8+1 or 9+1 ? the +1 is the overload .

i like my 22-547 springs . nice lighter ride . and i put in timbren bump stops for when i am loaded heavy .

posted just for the spring specs info on the part # i posted up . https://www.sdtrucksprings.com/index...oducts_id=7356

Re: G 50 spring option 1976

My original springs are 8/1, a little less than a 3" spring pack, I'm guessing they're rated at 2600lbs? Just wanting a simple spring setup, no over loads or bump stops, I don't mind a little stiffer ride when M/T. I ended up with a new set of 9/1 General Springs #22 617, rated at 3955 lbs, 4 1/16 pack. I think that may really affect the ride when empty though.

you will know there in there . . .

you can always pull a leaf or 2 per pack . but space them apart if you do . dont pull 2 direct leafs . ex: #3 and #4 . . . go #3 and #5 that kind of spacing .

Re: G 50 spring option 1976

I talked with General Springs today and they said that their 2600 lb spring was the same as the GM G 50 HD spring option, and their 3500 lb was custom and never offered thru GM, it would also raise my vehicle a little, so I ended up ordering the 2600. Thanks for the replies.
