i have a 2001 dubcab w/revtek 3" spacer. the stock front springs have sagged about 1 inch. if i go with ome 880 coil springs will this get me back to where i was. what would be the pros and cons of this. i know they claim about 1.25 to 1.50 lift. or if i do away with the revtek spacer will the 882's give me 3" of lift?
