best way to lower rear 4"

[bautino95]

Hi, I want to do a 2"/4" drop on my 1971 c10 truck. Its not a daily driver but I want to maintain has much hauling suspension travel for the rear as I can. I was thinking I would just use 2" drop coils up front and either 2" or 3" drop coils in the rear and make a 1" or 2" lowering block to make up the rest of the rear drop depending on which springs I get for the rear. Ex: get 2" rear coils and 2" block or 3" coil and 1" block to get the 4" drop in the rear. Would I need shock re-locators if I lowered it this way? Or should I just buy a complete 2/4 kit with re-locators and panhard bar shocks ect... Hope all that made sense. Thanks
