My lift is done. After customizing DS 1” front spacer (machined to 0.8”) and 1.5” rear FJ spacer (machined to 1”) my total lift is: 1.45” on the front and 0.95” rear: exactly what I wanted.
Total cost was $212.60: $69.26 for spacers and $143.34 for lifetime alignment.
I did work by myself, it was not hard just time consuming: around 4.5 hours front and 1.5 hours rear.
I was worry about compressing springs (rented spring compressor form Autozone) but that was not an issue at all. It was easy and maybe added 1 hour to the whole job.
One thing I noticed that my truck got slightly quitter especially the rear. I guess that is a one benefit of using DS spacers.
Thank you all for all help!
