Strut for Rear Cargo Storage Bin

[cs15dah]

Anyone have a part number for the strut that holds up the rear storage bin’s lid, which is also the cargo area floor?

Don’t know part #, but I can send you a list of GMC parts sources?

[cs15dah]

No, don’t need that. Online GM parts websites don’t show it. Some sites show the storage accessory as a whole, but doesn’t list the strut as a separate purchase item/part number.

There isn't a part number (or any number) on the back side?

Awesome; thanks!

 

Part comes back as a "hinge-load."  Maybe not the right part?  Where did you find that part number?  "Hinge" may not be right.  "Load" well, yes it supports a load, so maybe its right?  No accompanying photos across any websites I've checked, so not sure if I'll take a chance on it just yet.

Brand appears to be AVM.  APY22145 is listed on the left and 1024 on the right.  Couldn't find any info on those numbers, or AVM, online. 

 

I'm thinking maybe the previous owner replaced the OEM strut with this one, and it's not correct.  It doesn't "appear" to be worn out, but definitely won't hold up the lid.  So maybe the weight is wrong.

 

I measured the strut from ball to ball at 12.8"  Closest I could find online was 12.5" with a 24 lbs force.  Installed it, and also does not support the weight of the lid.

 

I couldn't find a 12.5" with a heavier force. 

 

Next length up is 13" but is also 24 lbs.  Moving the lid, appears 13" would fit.  But if it too is 24 lbs, not sure the extra 0.2" will make any difference.

 

I see some longer lengths that have a force of 70 lbs, but think that's way too much.  At 24 lbs, it seems like I'd need maybe another 10 or 20 lbs to make it work.

That part number appears to work!

 

Found another site which shows "gasoline strut" in the description.  Awesome, I'll get it on order.

Tried to order that part from GMPartsGiant but found out it’s discontinued and no longer available. 

I believe the failed one in my truck is an aftermarket one, so taking measurements on it isn’t reliable. If anyone has the storage box and has time to measure, would you please let me know the length of the OEM strut both fully open and fully compressed? I wish there was some way of telling how many pounds the OEM one is... 

 

Thanks!

Did you try a Google search with the GM part number.

I'm running into the same issue on my 2018 Suburban.

 

I pulled the unit (APY22145) and since it's the same P/N as CS15DAH had, I think that is an OEM part.  Overall the length between pivots is 12.6" and the closed length is 8.8".  This means the stroke is 3.8".  Based on my measurements, the actual stroke needed to close is around 3", so there's some flexibility.  It uses a 10mm ball mount, which seems very common.  I have a quick drawing below.

 

I found a couple of options on Amazon.

 

The first is by BOXI and have almost identical dimensions.  Lifting force is 36#, which is about 12# more than the ones CS15DAH found in the post above, which is the lower-end of what they thought was needed.  They come as a 2-pack for about $20.

(https://www.amazon.com/gp/product/B01HLYT2J2/)

 

The second is by Pamagoo.  They are about 1/2" shorter (12.2"), have a longer stroke (4.7") for the 35# version.  They're available in 35#, 40#, 50# and 65# versions.  Some have slightly different lengths, but all have at least 3.5" of stroke.  They come in 2-packs and range from $18.50 to $22.

I think the 50# and 65# versions are probably overkill, and might not let the cover stay down.  My truck came with a WeatherTech cargo mat, so it'll have a little more weight.  I'm going to order a pack of the BOXI struts and see how it fares with and without the mat.

I received the 36# strut today and put it in.  It holds it up.....barely.  As in "only when it's all the way up, and without the cargo liner."  If I nudge it, the whole thing drops.

 

So, I reckon the 40# strut isn't going to cut it.  I'll be ordering a couple of the 50# units to see how they fare.

This helped me so much… I bought the wrong size initially on Amazon and then did more research and found this thread… the #50 works perfect to hold up the door and extra rubber mat as you described. Thanks again for doing the homework for me!!!
