Interestingly enough, I was looking at Bilestien shocks yesterday and Shockwarehouse had some very resonable pricesses on them. My truck is coming up on 70k miles and I am looking to replace my stock shocks. I looked at the Bilestein 5100s and the HDs, but I am not sure which to go with. I have a 1.5 inch leveling kit on my truck with a super spring in the back. I am running 305/55/20s and occasionally pull my 21' bass boat. I guess what I would like to hear are some opinions on which model to get (e.g 5100s or HDs) 95% of my driving is on highway with less than 5% towing.

 

I'm running HD's on my 11 and had them on my 07. They are by far the best shock/strut I have ever owned. And when I noticed them feeling a little soft at 99K miles. Bilstein didn't play any games, they offered up a replacement set at half price. With a contengency of, ship them back, if they find any issues. I will get a refund. Well, I got 4 new HD's on my 07 for free. Bilstein is the way to go. Period. Either will give you a huge improvement over stock.
