Additional Information

The CURT class 3 trailer hitch is the most common type of trailer hitch installed on full-size pickup trucks and SUVs. It is also found on full-size cars, crossover SUVs, minivans and mid-size trucks. That is because the class 3 packs the punch of a heavyweight hitch while still staying light on its feet. This CURT class 3 hitch offers a gross trailer weight capacity of 4,000 lbs. and a comparable tongue weight capacity of 400 lbs. It is designed to be a custom-fit trailer hitch for certain years of the Mazda CX-9 (to verify your vehicle compatibility, see the CURT application guide at It features a square tube frame and comes with all necessary hardware for a complete installation.

The 2" x 2" receiver tube opening of this class 3 hitch is able to accept a hitch-mounted accessory, such as a bike rack or cargo carrier, or a ball mount to tow most standard size trailers, including utility trailers, single-horse livestock trailers, boat trailers and large campers (NOTE: Never exceed the lowest weight capacity of any towing component).

CURT class 3 trailer hitches are engineered to be strong and capable, having a quality steel frame and a solid finish. They are put through strenuous testing before being deemed ready for market and come with two coatings -- a liquid Bonderite coating and a powder coat in high-gloss black -- that cure together to form a strong resistance against rust, scratching, UV damage and other wear. Our hitches are our pride, and as such, we back them up with a limited lifetime warranty and a one-year finish warranty.

Fits like a glove - looks great!

Was able to install this in 30 min and I'm an IT guy, not a mechanic. Would have been less if my 3yr old wasn't helping. Lining up the bolt holes takes the most time - requires a bit of wiggling around. Just start all the bolts before tightening any up because you may need to change the order in which ones you start first. Love it! It looks fantastic!

Model 13575 Hitch

This is a great hitch. And this baby is made in the USA! Straight forward install. There are even paper wraps on the hitch to protect it from the racket handle hitting the hitch when tightening down the bolts. For a DIY'er it took about 45 minutes to install. Tip: You are working with tight tolerances; so, get the spare tire and spare tire hanger out of the way to make it easier to install the hitch. Doing this will actually speed up the installation. Also, point the hitch side mounting plates straight up under the car while aiming for the mounting holes in the car frame and rotating the hitch up into place. Have the bolts laid out on both sides of the car to make it handy to get a bolt in place on each side to hold the hitch up for the other bolts. Leave the bolts loose so you can move the hitch around to get all bolts started. Ratchet down the bolts until very tight and finish off with a torque wrench.
