I've got the DR 4.5 ( 1" TEI on the way) with 5" DR springs with a 1" block. Tows no problems, i tow a gooseneck, bumper pull and 5th wheel.... But DC is correct, the 5" springs are a little softer and tend to sag a bit, but it's not too bad.... Are the new Icon springs softer than the old DR springs??
