By hockey puck your talking about a spacer right? If so you have a few options you can use a daystar kit PN-KF09108F6L Link- http://www.suspensionconnection.com/...F09108F6L.html
or I beleive skyjacker made some "leveling springs" also you can use the spring perches off a 90's F-150 that sit on the bottom or you can use F-150 coil springs.
To instal pull spring out put spacer/coil in bolt everything back in place
Edit- the webpage is just a ref you can find them cheaper
