Had off today and went to my buddies shop today and we put the TF leveling kit. We started at 505pm and were done by 615p... That includes smoke breaks between front/rear and taking off and remounting the tires.
Once we had it up in the air we only disconnected the lower shock and took the front sway bar off. Got the springs off and added the pucks and isolator... Went back in without issue. Front was done in 20 minutes.
The rear, we popped the lower shock bolts and sway bar, unhooked the abs, parking brake etc. took spring out and I was able to hand push the rear spacers in. Took about 20 minutes... The rest of the time was spent just preparing to do everything... And having a few cigarettes.
I'm not a "car guy" and have never really worked on anything myself... So basically, if you're debating on doing it yourself... It's easy(yes... Having a lift and the pneumatics was a huge help)
I'll try to get some better pics tomorrow.
Eta: JK has 14/55 springs.
