my blazer is lowered 4 inches in the back and when i go over bumps in the road the underbody above the rearend, it hits hard and sounds like crap, tried bump stops but makes the ride really ruff. i need simple solution until it gets bagged.

if it hits the frame rails, notch 'em. thats really the only thing you can do.

i have a bagged blazer all you can do is notch the back. you can buy a bolt in small notch that notches the frame like 2inchs from suicidedoors.com its only like 40.00 i think wich really aint that bad for ride quality. and the good thing is that make a notch for the crooked frame blazers and the straight frame. hope that helps TinnMan
