If you end up doing this with Syndicate or someone else in CA, let me know. I will give you my cell and you can call me if you hit any road blocks. There is also a thread on XOC where two of us who have installed the lift have posted hints and tricks.
It is a really logical install. Air tools will help, but not necessary. Breaker bar is a must. A mix of deep well sockets too. You will need to borrow or buy a torque wrench if you don't have one.
Calmini estimates the install time for a shop to be 6-10 hours. If you end up paying someone, figure $80-100 per hour...it is $80 in Utah.
If you do it yourself, it will take you more than a weekend, so plan for some down time.
