Review on Hellwig 553 Helper Spring by Daniel Jackson

Assembly is very simple and complex. I did this with my truck in the air only to find that it should never be installed unless it was on the ground. The instructions are very simple, but leave many questions unanswered because they describe almost nothing. My only concern is that when my truck is on the lift, the u-bolts will just dangle and the springs will stay loose. Sag is almost as bad with a trailer.
