Today, we're gonna take a quick look at the Thule replacement aluminum shank adapter. This is gonna allow you to convert your inch and a quarter shank on your Thule bike rack to a two inch shank. So that's gonna upgrade your shank diameter, so it's gonna git into that two inch by two inch hitch receiver.This is going to be a direct replacement from Thule for the following bike racks. It's gonna the TH945. The TH912. And TH914.There's gonna be a couple of the older style of Thule bike racks.This is gonna be made of a durable, but lightweight aluminum construction, so we don't have to worry about any rusting or corrosion.
We'll have our hitch pin hole here. That'll accept a standard five eights inch hitch pin to go through there, or you're anti-rattle bolt that came with your bike rack.And then we'll have the actually attachment location here.Now, this doesn't come with any hardware, so if you need the screw to attach that on to your inch and a quarter shank, that is sold separately. You can find that here at etrailer.com using part number 853-5787-02. That's just gonna be a little M6 by 16 millimeter flat cap screw that fits inside there. Just fits right down in place.
It'll be nice and flat so we don't have to worry about any obstruction for our bike rake itself, or for fitting our shank into our hitch.And it'll also have that nice black powder coat finish, so it'll stay looking nice, matched the rest of our bike rack.As far as our dimensions, it's gonna be 10 inches long, going from end to end. The width, of course, will be two inches, outside edge to outside edge. Our inner diameter or our inner measurement, excuse me, is that one and a quarter inch, so we can fit it over our original shank on our Thule bike rack. And then the distance from the end of the shank to our hitch pin hole, is one and nine sixteenths inches.And that's gonna do it for our quick look at the replacement aluminum shank adapter for an inch and a quarter to two inch from Thule.

Thanks for reaching out. The product is still working perfectly, looks the same as it did a year ago, and allows us to use the Thule bike rack regularly. The product is significantly better than the part we bought from another retailer.

Thank you for taking the time to leave a review. This adapter is intended for specific Thule models, and is not compatible with all models. We do not recommend modifying the product. Thanks!

Replacement parts can be difficult to narrow down since so many of them are so similar. We can help with that, particularly once we know the model number of the rack. Give us a call or send us an email.
