1996 Blazer LT Front And Rear Suspension

I am interested in stiffening the front suspension of my SUV, it seems a little spongy as well as
when driven higher speeds, it floats like a boat, sways and nosedives. I also notice the rear suspension sways a bit and bounces also, is there a kit that will fix this problem on the market?
I am also looking to lift at least an inch for a little extra travel. I am a mild off roader, but I am concerened about how the suspension is handling at this time..I used to own an 84 S10 Blazer
2door, and it 4wheeled like a top, very responsive, I would like to get the same out of my 96..
Any suggestions? Thanx..

i have a 96 blazer four wheel drive and i went through three pairs of shocks until i found KYB monotube shocks and they are awesome. And with my personal expierence its not a good idea to lift a vehicle with independent front suspension.
