Suntour XCR forks 8552 there was a lot of play in the bushes after only 3500 miles but they held together until they finally clunked their last after 8500 miles.
Rockshox Reba forks 6000+ They've been on this bike for 3500 miles but they'd been done about 3000 miles on a previous bike before this.  They're still working perfectly, no play or leaks and have never been serviced.
