4.0 5.5" rear lifting block 97 Suburban

I wanted to lift the back end of my Suburban. The truck already had a 6" procomp lift kit, however the back end was sagging. The tech recommended 5.5 lift for the rear. When it was first put on it looked awesome. It had the exact lift I was looking for, BUT after I filled up with 41 Gallons of gas it sagged about 1" giving me that front end higher than the back look. IF I do it again I will go 6" block in the rear. OVERALL I am happy with the look when the car has about 1/4-1/2 tank.. The installation was top notch and the salesman was friendly and knowledgeable. I would recommend 4wheel parts to everyone.
