Lift kits

I'm thinking about doing a 2.5" lift soon to smooth up the ride a little and to give my truck a little more aggressive stance. Has anyone here done this? I'm looking at the skyjackers as they seem to be the most reputable and I hear they smooth the ride out some which IMO is

Much needed on these 4x4s. but let me know what you guys have and pics would be appreciated. I'm also thinking about a 4" lift with 35s.
