Your welcome! Glad I could help and let me know if you have any other questions.

My new Ridetech HQ shocks showed up today (ordered them Thursday). It took me a couple of hours to get them installed this evening. After installing them I took it for a short ride, and believe it or not, I could feel a difference as I was backing the truck down my driveway. I only took it on a short drive, but I'm already impressed with the difference in the feel of the truck. I'm going to drive it to work tomorrow and I'll give a better report, but so far, I give them a big thumbs up! OBTW, a BIG THANKS to board member Crawdadfox for getting my order shipped quickly, .

Were they Part #: 22189841 (rear) and Part #: 22149841 (front)? I didn't see anything pertaining to a different part number for a lowered truck.

Thanks!

Mark - measured the difference between mounting points on my front and rear shocks and then called Ridetech. They recommend the shock number that I should buy base off of those measurements.

On a different note, I changed out the axles hoping that the rear vibration/hop would go away but it didn't.... So I got to looking at the rotor/axle hub where the rear wheel bolts on and you can see where the wheel isn't bolting on centered. I think the CPP rotor is so thick that very little of the hub area is sticking out past the rotor, so the wheel is not centering up on the wheel flange. I have the cone style lugnuts but they are not forcing the wheel to center up, which is causing the rear to bounce. . Not really sure what to do now....

I actually read an post somewhere that said one of the axle tubes had tweaked under load and caused this same symptoms... This was a 1000hp truck... but who knows what it would actually take to tweak one...
Just a thought... I will see if I can find the post...

I don't believe it's an axle tube. This problem started when I rebuilt the rearend and added the rear CPP disc brakes. I had these wheels on with drum brakes and had no such problem. I'm pretty sure it's due to the fact that the wheels aren't centering up on the hub when I bolt them on. I'm going to pull a rotor off and bolt the wheel on and see if I still have the same problem.

Yeah I could see that being an issue as well...
