I have a 4.5" lift and want to upgrade to a 5.5" lift, but don't want to spend all the money to buy a new lift. Is there anyway i can just add an inch front and rear with out spending too much?

 

You can add a coil spacer in the front and a spring shim in the rear.

Also, as an alternative to the rear if you just have a leaf pack with stock shackles, you could get lift shackles. I'm pretty sure Teraflex, JKS, and Daystar make a 1" lift shackle. Just go to Quadratec.com and have a look around. But coil spacer for the front and shackle or shim for the rear will get you another inch.
