So older ones from 70's and 80's?
Just so you know, by the time you get it all setup and do it right for a JK, you'll most likely be in it for about the same cost as a new 60. Just something to think about.
What are the 60's running now front and rear.
2011 JKU 3.5 R.E. Longarm lift.
If your wanting to do new 60's with all the bells and whistles, full float, 8 lug, stub hubs, pro steers, etc. can run 17 to 20K+....cheap brand that are semi float 5 lug, stock brake assembly retained, etc. can be as cheap as around 10K. If you have the money to spend 10k then I would save for the better 17k that will outlast the jeep!
If you do all your own work like installation of carrier/locker/R&P/brackets and you shop smart and can wheel&deal it can be done with junkyard axles for 5-7K
Not exactly. You can get a basic new rear 60 for about $4500 and a front for about $7000.
That by itself is nicer than a junkyard set of 60's which will cost you about as much if not more to get setup for a JK.
