My Blazer as a half ton truck was no less than dangerous to drive. It had a 4" suspension lift and 3" body. It had 36" Dick Cepek tires. One small bump and it would change lanes. Come to find out the tires just were not up to highway driving. I Changed them out for 10ply Super Swamper Radials and WOW. I also Changed the axles to one tons but I believe it was mostly the tires that made the biggest difference. After that the thing was on rails. It drove like a car. The suspension was still a bit stiff and had I not wrecked it I would have changed the springs to 73 up style.
I did swap out the rear shocks from 5000's to adjustable 9000's. That made a huge difference. I swapped all the suspension to my 70 SWB and it is the same deal. Drives straight as an arrow and very solid on the highway. Oh and I did put a frame strengthening brace behind the steering box. I think I will put one on my 2WD Blazer as well.
