Rear shocks

Hello I did a search and it appears most people change the rear shocks in order to lift the SUV; however, today someone hit my SUV while it was parked. Luckily they stopped and I got all their info. I would like to keep my ride height and have Blisten HDs in front. Are there any shocks that anyone would recommend that keeps the ride height? I do have the tow package on my vehicle.

Also, I am going to get new running boards out of this...anything good out there cause I hate the OEM ones.
