OME CS055R and reg. 5100s?

Stupid question but wondering if I can use my 5100s with these leaf springs?(thinking no)
Really only wanted to raise the rear 1-1.5"s but seen a good deal on these.
I have a truck cap and carry alittle weight, my springs are flat, probably more than flat. Don't think an AAL would be my best plan but I really don't know.
I have 5100s in the middle postion and with the weight in the rear, my truck looks level or alittle squatted to me.

 

Why not custom leaf springs? I feel like you get more value with custom springs tailored to your vehicle weight and driving style. Off the shelf stuff is fine, but you may be stuck with something that's too soft or too stiff.

 

Living in rural Canada, not to many options but will be looking into it.

 

I don't know of any custom leaf spring manufacturers up there, but you can talk to Alcan, Deaver or Atlas and they can make custom packs and ship them up.
