Replacement Bolts for Curt Trailer Hitch # C13105 on 2018 Toyota Sienna


Just bought the Curt # 13105 hitch for my Sienna from a neighbor but don't have the mounting hardware. What size bolts does it use? Do you offer the hardware kit?


Expert Reply:

The Curt Trailer Hitch Receiver # C13105 that you referenced, which is confirmed to fit your 2018 Toyota Sienna, uses six M12-1.25 x 40 hex bolts and six 1/2 inch conical toothed washers for installation. We can indeed provide you with this hardware kit with part # RHK. Once on the product page simply select "Curt" in the dropdown menu and type in "C13105" in the part number text box. We will then send out all the needed installation hardware for this hitch on your vehicle.

I have attached an installation video and the written instructions that you can also use for reference.

If you have the same Curt # C13105 mentioned above (which is a fit for your 2011 Sienna as well), the bolt and washer size is the same. You can obtain a full replacement set using the Hardware Kit # RHK . Pricing is listed on the product page. If you have a different hitch model just let me know.

The picture on the # RHK product page is just a sample image - it's not actually what the kit for the Curt hitch on your Sienna consists of. We use this part number for the replacement hardware kit of every hitch we have available - but as soon as you type in the hitch model number (C13105) inside the text box provided and select "Curt" in the manufacturer drop-down menu, we will send you out the exact kit for this hitch on your vehicle.
