question on rear suspension swap

[junkyardpartseeker]

I have a 84 1/2 ton suburban and am thinking of putting a set of 20 series rear leaf springs on my rear. I pull a lot of heavy trailers and it seems to ride too low in the rear for me.

1. What do I need to perform this?

2. Can I use my rear axle I have now, or do I also need to get the rear axle from a 20 series vehicle?

Any help would be appreciated.

Thanks

junkyardpartseeker,

I would recommend switching out the axles as well. The only problem is 3/4 ton axles are 52" long and 1/2 tons are 56" long. If you do the spring swap you will have to drop your gas tank and move your two rear spring hangers forward 4". I just swaped mine from 1/2 to 3/4 and it wasnt as hard as I expected but there was a little more work than I expected.

Hope this helps,
