bilstein shocks ?

I am old. and admittedly a little confused. But still mechanically active.
I have 2003 GMC 2500hd Sierra duramax 6.6L LB7 145K miles. I loaded up a lance 8'6" camper for last summer. But after a couple of months, i noticed a groaning sound from the front end. I have original ac shocks. every thing else seems tight. the shocks however look worn the rubber is cracked etc. The noise is very noticeable first thing in the morning, then settles down and only groans when i try a tight turn. Or put it in 4WD and turn tight.

I'd like to replace the shocks but i confused by all the options? I have air bags in the back. But i don't think the truck is lifted? I mean it's all stock and it's high? 'been looking at shocks and the bilsteins seem like the most recommended. But there are question about the lift? How do i know what the Torsion Key Lift is?

When i bought the truck, i remember i did something with the torsion bars to make the front end level. It had downward rake? I probable sound like an idiot. But i have forgot how i did it. I vaguely remember something about colors and height adjustments but just can't remember. I don't want to pay to have shock installed, at $80 an hour.
So How do i know what size shocks to buy? Measure the Old Ones? I live in a very rural part on Northern Ca so i normally buy online.
Thank ToOld

You can measure compressed and extended heights, but really as long as you don't have a lift kit installed the Bilstein 5100s you'll want are 24-186735 for the front and 24-186742 for the rear.

Should be touching the bump stops....if you have any left. Might wanna inspect those for condition, as they're in integral part of the suspension up front. You'll be in there for the shocks, easy replace at that time.

Shock replacement on these are barely a 1 level on a 1-10 scale (unless your tool box consists of a pair of pliers and a flathead screwdriver). I wouldn't even think of having a shop put 'em on.

I too have installed the 5100s on my dually and have very happy with them.

Hook is spot on. Changing out the shocks is something that you can do in your driveway with minimal tools.

Bilsteins are super expensive. The Gabriel "Max". are $40.

Gabriels are a good shock, and a good value.

5100s here as well. Still comfortable but does the job well when I am loaded. I replaced the bump stops as well. They were beyond shot. Both are a very easy install and I am not much of a wrench either.

I put the Bilstein 4600's on the front of my crew cab dually last month. I have air bags and haul heavy. Probably wouldn't hurt on the rear either but it is stiff enough it doesn't bounce up and down all the time.

Wish I had installed them when I first bought the truck. There was nothing wrong with the OEM shocks when I pulled them off, they're just way too lame for a heavy, hard working truck.
