I am going to replace tail gate struts because they don't open the gate all the way up and cause an error on the dashboard, it looks like Stabilus is the Acura's OEM supplier.
OEM Catalog shows 74820-TX4-A22 (~$130 for 2) for my 2017 Acura RDX.
The old ones say 74820-TX4-A210-M1 (Is it 74820-TX4-A21 ?) It seems like 74820-TX4-A22 is a replacement for 74820-TX4-A21 (~$130 for 2).
According to the Stabilus catalog I need 4B-880754 (~$50 for 2)
There is an option to buy AISIN parts (~$36 for 2)

What do you recommend?

Check out this 'stabilus' one from rockauto:

 

Yes, this is it.
They will cost me $58 for 2 of them (with taxes and shipping fee), I see better prices on ebay.
My question was more about what to buy not where to buy, so Stabilus 4B-880754 is a good choice, right?

 

This is the best I can find on ebay shipped before taxes.


This is the best price I can get on RA shipped before taxes (sent to S.FL) and I don't have to 'sweat' whether they are fake or not.
Negligible in OTD cost difference.


Answer your own question.

If the 8 to 9 years of utility received from the old Stabilus factory OEM component pictured below (possibly made in 2016?; red arrow) is not reasonably acceptable to you, then try another brand, no?

 

Yes, this is where I am going to buy it. It's a legit high volume seller with good reviews.



My rockauto prices:



Yes, it's absolutely reasonable. Thanks.

 

Well done!
Just an FYI, the 'always available with a google search' 5% RA discount code comes in handy to almost negate sales tax.

 

Any comment on how fast these raise/lower? The OEM that are now 13yrs old are awfully slow going up and down!

 

Just to let everybody know, these solved the issue. They look like original ones.
The new ones did not get any faster but I don't care to be honest, I am not in a rush
