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 Lexus RX 350 or Lexus RX 450h (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. One special feature about the class 3 that is not found in classes 1 or 2 is its compatibility with a weight distribution hitch. When used in combination with a WD hitch, this class 3''s gross trailer weight capacity increases to 5,000 lbs. and the tongue weight capacity to 500 lbs. (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.

Lexus RX 350 trailer hitch

I just finished the installation of my trailer hitch. Very easy and clean installation. Well engineered parts, clear instructions and a simple and secure fit. Took about 45 minutes. Completely satisfied.


The only issue I had, were the coated bolts needed a little extra wiggle room to fit through the holes in the hitch. I used my dremel to simply clean the hole a touch and then everything fit perfectly (do a test to make sure your blots fit before laying under the car with the hitch hoisted above your head, only to find out the bolts are a little too snug to fit easily through the hole). Otherwise, hitch looks great, install was outlined well, and went pretty smooth.

Box arrived on time and Hitch installation was easy. Everything lined up perfectly. My only suggestion to Curt would be to pad the ends of the unit. The ends and the receiver were poking out of the box and the coating was chipped, which I repainted. All in all extremely satisfied.
