First gen rear shock help

Hey everyone I was wondering what you all thought about the kyb rear shocks as I ordered them today off Amazon for $35 a piece. I just got a message back from someone off fb market that has used he said for about 500 miles of a pair of bilstein rears off a trd wreck. Here is a pic. Should I cancel my kyb order and see if I can get these delivered please help.

 

I put KYB on an Acura RL once, and I've run nothing but 4600 series Bilstein shocks on my Toyota trucks. That's almost 30 years using Bilstein, and not a single problem.

 

I finally replaced the original Bilstein's on my 2008 TRD Tundra 4x4 with KYB gas-adjusts on the rear and KYB gas-adjust strut-pluses on the front last month at 183k. They work just fine and were half the cost of Bilstein replacements. Though I plan to drive it until it quits I didn't want to spring for the Bilstein's. They were still in pretty good shape but it was time to replace them. The KYB's are as good as the Bilstein's at the moment but it remains to be seen if they can also go 183k.
