I installed the Billstein 5100's on setting 6 last night after work and took it in today to get the tires (Toyo Open Country AT3 285/55/22) mounted and the truck aligned. I love how it looks. Tires and shocks firmed up the ride a bit and it feels, "heavier" or "more substantial" I guess. I noticed that the passenger side is 1/2 inch higher on the front than the driver's side, not sure why though. I checked the groove on the shocks and both are at the number 6 spot. There is a slight amount of rubbing on plastic on the passenger side but it's just on plastic so Ill "fix" it. A week ago I used a DB meter to check cab dB on a few diff roads. I only got to 1 of those roads with the new tires so far. My decibel reading before at 50 MPH was 78 to 81 dB, now the same stretch at 50 MPH is 83 to 85 dB. I'll check the freeway at 80 tomorrow or Friday.
