Raise Swinger rear 2"

I can have my tire shop add leaf springs for $300, or try it myself at maybe a little less cost but I'm not sure exactly what product I would need to do it, would one of these helpers from JC Whitney work? Thanks.

$300 for add a leafs? call espo and just buy + 2" springs and do it the right way. http://www.espo.com/
