Yep, have my second set of them on the rear and the first set of them still on the front with thier replacements on standby. The OEM's lasted to 23,000 but I didn't record how long the first set of HDL'S lasted. I want to say I had between 15 and 20,000 miles on them before I replaced. Some of those miles were pulling a trailor.
I usually wait for HDL to have a sale and stock up on stuff like that. But when you need them, you need them.
