xreas suspension replaced

I purchased my first 4Runner, a 2015 Limited, in August, 2020 and soon-after learned that one reason I got such a great deal on it was that the xreas system was leaking and needed to be replaced. My Toyota dealer said about $4200, but did suggest I consider scrapping the system and replace it with conventional Bilstein's for only $3500.
I did a little shopping online and found the proper Bilstein B4600 heavy duty shocks and struts at Shock Warehouse for less than $400. They were on backorder so I waited until January for them to arrive. I shopped for local installers in San Diego and got two estimates for $1600 + or - for labor, plus a couple places that wouldn't install owner-supplied parts. Still too much.
I struck gold on my third estimate; Suspension Plus, a 25-year-old business with a 4.6* rating from customers, for $650. They had a no-problem installation, and 4 hours later I was cruising on my new suspension. The Bilstein's feel firmer and more positive. I'm very pleased with how everything came together ... Oh, yeah, I DO LOVE MY 4RUNNER!

 

Great first post! Nice to see someone do the research, formulate a plan, and execute it. There are too many that want a spoon fed solution.
You'll be much happier without the xreas even if it was working properly. Thousands of owners have gone with some sort of Bilstein set up over the years, with good success.
My LE shocks were working just fine and although adequate, that system is not the best for the kind of driving I do.
