There is a lot of great info on here if you search. Toyota dealers will only replace with factory installed components so I decided to ditch the XREAS. I have a 2006 Sport Edition V6 with just over 140000 and my XREAS was shot. I purchased front struts and rear shocks from a 2014 Tacoma TRD Sport edition locally for $50. Purchased a set of rear 2014 FJ Cruiser springs for $100.00 shipped from a member over on the FJ Crusier forum. I had a local 4x4 suspension shop install and do an alignment for $500.00. Total cost $650.00 and she is riding like a new truck with a little bit of lift as a bonus. ARK_SWAMPER started a thread on this swap and has great info on this. You have other options too like the Bilsteins and FJ coils. I just did this a few weeks ago and checked craigslist boards all over for parts, there were a few sets of coils in Atlanta and Ashville, NC that I was considering, they might still be available. Good luck! I don't know what I would have done without this forum.
