Today we're going to be taking a look at the replacement speed knob and wedge assembly for the Yakima bike racks, part number 8880508. The Yakima replacement speed knob is to be used with the Full Swing, Swing Daddy, Ridgeback and Full Tilt bike racks when their speed knobs are either damaged or the threads at the end are stripped out. It comes with the black knockout here which you're going to remove that and it has the control key to remove the lock core from your previous speed knob to replace it into this one. To get started we'll first remove our wedge piece here by unscrewing it and set it aside now we'll grab our damaged speed knob and start replacing it as well. Now we'll move on to our bike rack and have our Yakima Ridgeback here on our table and the issue with is the thread is stripped out in our wedge. We'll push that off to the side, remove our speed knob as well, now we'll get our new one and start installing it. First since this is a Ridgeback, we'll have to remove this top piece from the wedge. Take our allen tool, unscrew those two allen screws, move onto the one on the inside.
Now we can grab our new wedge and install this piece on top of it. What this piece actually does is it takes up the additional space on our Ridgeback so it'll fit properly in a two inch hitch. If you we're to convert this into an inch and a quarter you would remove this piece again. Finally, our second screw, one last turn to make sure it's nice and tight. Next we'll move onto our lock core switch out here. To remove this plastic cap, we'll take a small flat bladed screwdriver and just pop that out, very easy, and then we'll take our master key here put it into the core and it pulls out like so. Again, very easy.
To place it into our new lock, we'll push it in holding onto the end of the core and pull it out. Now we're ready to install this. We'll take our lock washer and install it on our replacement speed knob here and we'll install it at the end of the shank like so. Then we'll take our wedge and we'll just start to screw it in on the inside. You see the cutout here, you want to make sure that the wedge fits along that area. Here's the end of our speed knob so we'll just match them up, just start threading it in so it catches.
Now we can place it into our vehicle, slide it into our trailer hitch and go by the normal installation procedures for this bike rack. Now we'll go into the end here and tighten down our new knob. As we tighten it down, you'll notice that the shake and play has gone away which means it's working properly. All right, it looks like we're ready to go, we'll lock it into place so it's secure in the vehicle and now we can load up some bikes. There you have it for the replacement speed knob and wedge assembly part number 8880508.

Arrived sooner than expected and works perfect! 866901
I use the rack regularly. I am not sure that mine came with a new key system, but I am happy using without the key. 863408
Exactly like the photo and works. It be nice if Yakima sold just the Wedge that threads into the end of the rod, as that was all I needed (as the wedge can fall out I'm sure that most people need to replace just the wedge, not the whole assembly). But this is not eTtrailer's issue as Yakima does not sell just the wedge (I called them). I'd also recommend that eTrailer predominately recommend as an add on buying a Yakima Same Key System (SKS) Lock Core as I'd have probably bought one (IF they sold just single lock core at around the same price as Yakima vs. a two pack). The eTrailer description does note that the SKS lock core (sold separately), I just didn't follow or understand what that meant until I got it and then understand I needed to take my old lock core out of my old SpeedKnob, and put the lock core in the replacement SpeedKnob. As I had my old SpeedKob with the lock core, it wasn't an issue, otherwise, I'd be placing another order for a lock core. 859643
Its a knob for a hitch mounted bike rack. it arrived well packaged and in good condition. SKS key lock core is sold seperately. The key pictured is for installing the core upon purchase. 857315
Got what i needed. This is the weakest part if the entire buke rack and the most subject to seizing. Buy 2. 829433
I was so impressed by myself and this replacement piece. Diagnosing the issue and identifying the part was the hard part. etrailer.com came to rescue not only by supplying the necessary part. But, by supplementing with the video instructions. Although, the instructions supplied were sufficient. Watching the instructional video was a beneficial go-by. Thank you for being there. God bless you and all who make up this asset. 829299
Etrailer made it simple to order. They had the parts I needed and shipping was fast. This is my go to place for bike rack parts! 828078
So glad to find this replacement part available. Great and fast service! 826120
This is the exact item that I needed. I LOVE that etrailer ships from the USA. Note that I originally placed an order through a company through another online retailer, and they cancelled the order on the day we were expecting delivery. I found the same part with etrailer and called to confirm they were US based prior to placing my order. The order process was simple, the shipping cost was reasonable, and the delivery was reliable. I will order from them again. 824275

I ordered a replacement part for my Yakima Bike Rack and received it within a few days. My experience with E-Trailer after several orders has always been prompt and responsive. Great company to work with. 589107
I couldn't find the replacement anywhere else including the original dealer that sold me my rack, this part is the right part number and solved my issue effectively. I've purchased more solutions from etrailer.com and every time is always a nice experience. I'm giving 5 stars, for some reason I can't rate with the stars on this comment box. 563265
