Best Suspension Lift Kit

[skid]

I have the original leaf springs and shocks in my Blazer, and they are pretty well pooched. My next purchase will be a lift kit and tires. I was going to get a Skyjacker lift, but read on another thread that someone wasn't happy with theirs. I've decided to go with a 4" lift with all new front and rear springs. Any opinions on who makes the best kits? Street ride is important.

Other questions:
Should I get a drop Pitman arm for the steering? Do I need to adjust pinion angle? Need longer brake lines?

Thanks in advance.....

I would sure recommend Tuff Country front springs, as I have been happy with their front springs. Haven't used their rear springs to give you advice on them.
