Stock 1/2 Ton Rear Leaf Spring Pack Size

[Charlie]

Wanting to replace my rear leaf springs. Currently have a 8 (7+1) pack. SPID code is G50-Heavy-duty rear springs. They are OEM. I am thinking that this maybe later on became known as a Heavy Half, not for sure. Looking to get standard stock springs. Not sure if it is a 4 (3+1) or 5 (4+1) pack for standard 1/2 ton LWB. Would like information for this. Thanks.

Also, if any DFW members can recommend a supplier would be great.

Hi, I recently purchase a 80 step side and replaced the rear springs. One thing to watch (I learned by mistake) is they made 2 lengths... 52 inch eye to eye, and 56 inch eye to eye. if you have the 8 pack, it is probably 56 inch. I looked on craigs list for mine.

Thanks, yea I knew there were 2 sizes, measured before but don't remember right now the length. I am wanting new if I can find them. Used might be ok, but probably weaker due to age.

I had my rear springs rebuilt by a local shop. My K30 was an 8/1 plus the auxiliary over load. My leaves did not sag, but I had a leaf broken on either side. To soften the ride a little, I had them remove 1 leaf. New bushings and spring glides installed. Cost was about $375 (California prices).

When I was researching rear leaf spring options I found Rock Auto's website very helpful.

Hopefully that link works...

It looks like the 7+1 spring pack is a 56" spring.

Looks like there was a 3+1 and a 4+1 but they are both a 52" spring.

You can drill out your spring hanger and move it forward- but that is a lot of work.

Could have a spring shop remove certain leaves and freshen up the spring pack (new bushings). This could change your ride height though...
