Questions/build: Warranty, leaf springs, pricing.

I can be long winded so pertinent info is bold. I want this to be my one thread to finish questions.

Okay, I have spent numerous hours scouring the forums for answers. I have found an insane amount of information on here (you have to often work to find it). I feel I am in a fine position to finally create a thread to fill in some gaps.

Background: I'm from jeep world (YJ,TJ). First new vehicle and taco arrives May. TRD Sport Cement.

How do lifts and warranties play out? Must dealer install to keep said warranty? What is ball park price for labor (Eibach pro, leafs, needle bearing replacement, alignment)?

I'm hung up on rear leaf choices... The Icon AAL looks nice and affordable. Any suggestions? Add-a-leaf vs entire replacement.

I am doing Eibach Pro all around (ordered from Tirerack today). Gonna order bushing and 265/75 or 285/70 on 16r (0 offset, 4.5 backspacing). Tires still up in air, love K02s on my jeeps but wanna get away from E rating if possible. Will do CMC if it is necessary after install, I'm aware of 285 controversy and no I won't do skinnies. (No clue where to have this done in Paducah, KY area).

A few notes that may or may not answer follow up questions.
-This will be a daily, but I have a work car ($900 Accord for my 10 mile drive to work). I don't care about MPG, drove a jeep for past 11 years.
-I hunt, so logging trails, fields, and nasty backroads will be frequented.
-The 2/1 level is for stance and better performance, I will not rock climb or mud this rig.

LED lighting eventually (comes with DRL), def doing Pro grill (sorry, its ubiquitous because its the best looking option, will take suggestions for others). Gonna look for a minimalist bumper to bounce deer off of and protect head lights, I know this is a long shot, and from what I read a little audio work eventually. First steps are wheels, tires, level.

Thanks for reading. I want this to be a be all thread, all advice welcome.

 

Dealers do not need to warranty after market parts but the must prove said parts directly cause an out of warranty issue.

The Magnuson-Moss Warranty Act, passed by Congress in 1975, is the federal law that governs consumer product warranties . The Act requires manufacturers and sellers of consumer products to provide consumers with clear and detailed information about warrantycoverage.
