Tuff country question

[Thebrownturd]

I am about to pull the trigger on a 2'' tuff country lift for my k20. I was wondering if a 3'' lift spring or a 2'' lift spring with a 1'' zero rate is better?

I ask since 4 wheel parts and summit offer a 3'' rear but, I haven't read of many people using it.

Also, I want to run ORD's HD front shackles and greasable bushings on all corners. Has anyone used them and if so were they worth the money? I live on a dirt road that gets maintained maybe twice a year. Anything I can do to stop squeaking and get a smother ride is worth it.
