Question on lowering a C20 ¾ ton

[BadAssChevy502]

I’m not up for it for a long time ,but I’m gathering info ,not sure on whether I should keep it stock height or lower it, I really like the dropped look with the big rims and low profile tires but all the trucks I have seen are all 5 or 6 lug rims C10 ½ ton trucks.

Are there dropped spindles available for ¾ ton 8 lug trucks, or are these the same as ½ ton
Are these the same for air ride bagged trucks
Are there complete kits for a 2” front and 4” rear drop for instance? Bagged or not
I was looking for a wheel setup like 20” rims with 295 or 305 x 45 20” or
22” rims with 295 or 305 x 45 22”

C-notch the frame is not an option because (I Think) our country does not approve these frame modifications, and I don’t want to be to low that I scratch the surface of the road.

And how much will it cost approx to do this conversion bagged or not (rims not included )

Thank in advance for all your info
