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
