Video Transcript for Yakima CoreBar Crossbars Endcaps Replacement Review

A lot of you guys are talking about how these end caps for the Yakima core bars are falling out over time. Well, as you start to put them in and take them out, they start to crack and stuff like that. And they just end up just falling out. So, what we're doing today is just replacing them. We have a quantity of two, so you buy them by the pair. So if you need to replace all four, go for that.

But if you just need to replace two of them, you can just grab one of them. So, it's literally the same exact thing that came with your core bars. They're going to fit the exact same but it's just gonna be a little bit more of a tight fit. So if you lost them, we got the replacement part for you, just so we can protect that inside. Since these are made of steel, making sure that this cap is on there is going to be ideal.

Because we don't want any of that to rust out. If water gets in there, it will eventually rust out. The outside is protected by some powder coat, but the inside is not. So, all you gotta do is just grab these end caps and they will fit on any length bar that you have. Just make sure you have the core bars.

If you don't know which ones you have, just make sure that you don't have a T slot on top. And if that's the case, then you got a core bar and these caps would fit. And that's basically it. There really isn't a whole lot to this part. It's just a replacement part to what you already have.

So if you need it, etrailer's got it..

Exactly what I needed. Fit my Yakima rack perfectly. Glad I bought a set because they are asymmetrical (there's a left and right side).



Still working fine one year later. Every now and then I push in on the endcaps for good measure but they are always secure.


Well, they are a factory replacement for the originals. I had one cap either get stolen or it came off in the carwash. Decided to buy 2 sets to avoid future issues with replacement costs and shipping charges.


These work great to replace the end caps that keep going missing. Don't know if they slowly fall out or sticky fingers get ahold of them. I might recommend drilling a small hole in the bottom of the rail and add a small screw to keep these in. That is my plan.


The product is great!
But...I needed
2 end caps for the passenger side of my rack, so I needed to order 2 sets because they are packaged in for the drive side and one for the passenger side. Is there a way to order single caps depending on which side of the vehicle??


It’s the details things that make a big difference and when the car wash knock the originals off, it’s just nice to have a service line eTrailer have a fallback option. Beyond that simple fix from inventory, the actual customer service by this team is just remarkable. Really appreciate the communication and updates, even for such a minor part.


Bought a camper shell for my truck, It has the Yakima crossbars but was missing the end caps on one of the crossbars. The fit was perfect.


Fast shipping to replace a lost end cap for Yakima crossbar. Thanks etrailer for making it easy!


Thank you for having this product and for shipping so quickly. We can no longer rely on Yakima to provide replacement parts so we greatly appreciate you!


Pops right in! Quick inexpensive shipping, too. No need to pay a fortune ordering direct from Yakima.


Excellent service at the right price for the item I purchased. Quick delivery as well!


Quick delivery and item as promised.


Fast and accurate service1
Thank you


I was impressed just how easy the process was. Found what I needed, the ordering was quick and I am very pleased with how quickly I received exactly what I expected. Just the way it should be. I’ll use in the future


Mine were old and two were cracked. These are perfect replacement and are actually still tight to go on. Will not come off easily unlike the old ones.


They arrived promply and work perfectly!


These are exactly what I needed and they shipped very fast


Not much to say. These are original Endcaps that fit perfectly.


Wrong parts


Great! These were easy to find with internet search, easy to order, quick to arrive. I am pleased with etrailer and will check with etrailer first for future needs.


Works great


great to do business with, fast shipping


They fit snug, even after a year. The 4 star is because manufacture had them back ordered for about 2 months.


Yakima never responded, etrailer, same hour


The product was exactly what I needed.
was manufactured by the original company and fit perfectly.


Incredible customer service!

For instance, if you had the Yakima CoreBar, you could use the Replacement Endcaps for Yakima CoreBar Crossbars # 8880640 for a replacement. If you can let me know a bit more information about what you have I'd be happy to help.
