I'm starting this thread to hopefully get some clear information out there on how to get Bilstein 6112's to work better with a 4th gen V8 and added weight.
A complaint I have heard or read about a lot is that the Bilstein 6112 shocks with the bilstein spring don't provide enough lift, even when on the top perch. I struggled with this for a bit and finally decided to pull the trigger on some new springs and fix the problem.
Here's the original setup.... Bilstein 6112 Shocks up front with the Bilstein (most likely rebranded eibach) 600# coil spring. The spring is a 3" ID (for the 2.5" body) and measures 14" in length. I'm also running Icon UCA's. In the rear I have the Bilstein 5160 shocks with reservoirs and OME medium 2" lift springs. After installing this setup I was sitting at 38" in the rear (ground to fender), and between 35.5 and 36.5 in the front which gave me more rake that I wanted and of course had the driver side lean.
To fix this issue I purchased some King 14x3" 700# springs and a 3/8" spacer. These springs cost me about $150 from Poly Performance. I installed the new springs and left the driver side spring on the top perch (#6) and also placed the 3/8" spacer above the top hat. For the passenger side I placed the spring on the third perch from the top (#4). After allowing this to settle the measurements I got were an even 38" in the rear and an even 37" on the front end. This was perfect for me. I am OK with this amount of rake and think that it makes it look so much better, and as it should with this lift.
If anybody produced a 15" 700# spring I think that would be a great option on the 6112's... unfortunately it goes from 14" to 16" which is probably too long. If there was a 15" spring it would allow us to use the bottom perches and still get the same amount of lift, but with less preload.
So, there you have it! If you want to get better lift from your 6112's, some 14" 700# springs and a 3/8 spacer could be put to good use. This would be good with body armor as well. I currently have sliders and a steel front bumper.
Feel free to comment with questions, I'd be happy to help.
