Annoying Noise

Hello Everyone,

Need some help here if anyone can.

I just had H&R Race springs installed on my 99 lude. I'm still running on stock shocks for now, until I can afford Koni yellows.

Now everytime I go over the smallest bump, I hear a banging type noise from the rear wheels. Both left and right.

Not sure if this is too low, I don't think it is. The total drop is about 2" front and rear.

I think this is shock knock?? Not sure and I don't know how to get rid of this.

Can anyone help?:confused:

Sounds like the bump stop. Who ever installed the springs should have cut the stops.
