I am installing RC upper control arms for 2-4” lift and RC sway bar links on Saturday. I currently have the 5100 on the top perch. I want to move them down to the middle perch and put a black 1” spacer on top and reinstall. Can anyone tell me if they’ve done this? I have an 08 2wd Titan. I’m shorting for a completely level truck. The 5100 on the front top setting still has some rake. It’s not completely level. Thanks for any help here.
