if its simply a leveling lift I have info and 2 options for you.
First bit of info is you don't NEED longer shocks. You may want them, but they're not necessary.
You did say yours are worn, so I would go 2 economical routes since it seems thats the path you're headed down. I've had both Monroe Reflex's and ProComp 9000's.
The reflex's are a nice silver finish, and have an integrated rod cover to keep crap from getting on the shock rod, and pricing fluctuates around $50each. Sometimes they run specials like buy 3 get 1 free. Not bad.
The ProComp 9000's are good shocks, but they're white. White isnt up to par for everyone, but a pricetag of about $35 for a good shock is up most people's alley.
Both ride great and perform well, as I've had both and now Bilstein 5100s.
I say either is a great cheap choice and being they're standard fitment you can get the Monroes from Kragen/Checker/Schucks and or the ProComps from Summit.
