UPS delivered my Billys and my 1/4" Toytec driver's side spacer on Friday so Friday night after my wife and kids went to sleep I decided to do some late night wrenching on my truck.
Install began late at 12:30 am Saturday morning. Everything went smooth. Let the truck down off the jack and the front was up way higher than the rear. Didn't panic yet because it hadn't settled. Drove it down the road. Pretty stiff but not bad. Got out and looked at it again and it was still too high. Took the yard stick that I did my initial measurements with (initial was 34 1/4 on driver's side) and I could not measure because it as higher than 36". It looked like the front was about 4" higher than stock. Checked to make sure I had the C-ring in the correct location and it was. Then it hit me...........I put the freakin spring perch on upside down on both sides. It was 3:00 am at this point and now I had to start over. This time it only took me 1 hour. I felt so stupid. I'm 41 years old and have been wrenching on cars since I was old enough to turn a wrench and I have never done anything this dumb. I never even considered that it was going in upside down when I installed.
Measurements before were 34 1/4 DS, 34 7/8" PS. After measurements are 35 3/4" DS, 36" PS so I gained 1.5" on the DS and 1 1/8" on PS. I love the look now and the drive is great. Not harsh at all. It is more firm but I like it. Rear 1.5" AAL will be next along with raising the front to the 1.75" position.
Edit: After searching the posts I see that I'm not the only dummy that installed the spring perch upside down. That makes me feel a little better.
