Features to know about

Get More Out of Every Drive: Class I 1-1/4" Trailer Hitch Receiver

This custom-fit hitch is built for light-duty towing and everyday utility. With a 2,000 lb maximum gross trailer weight and a 200 lb maximum tongue weight, it’s ready for small trailers, bike racks, or cargo carriers. The 1-1/4" x 1-1/4" receiver opening works with a wide range of Class I accessories, so you can haul what you need without overbuilding your setup.

Built Strong for Long-Term Use: Fully Welded Steel Construction

The sturdy, square-tube design and precision robotic welding keep everything tight and durable under load. The gloss black powder coat sits over a protective base coat to resist rust and chips from road debris. It’s built to handle regular towing or accessory use with confidence and consistency.

Simplify Your Install: Bolt-On Design Using Factory Hardware

Getting the hitch in place is straightforward thanks to the bolt-on installation—no welding required. It uses your vehicle’s existing hardware points for alignment and includes step-by-step installation instructions. Once secured, the concealed cross tube keeps the setup looking neat and tucked in under the bumper rather than hanging low.

Everyday Practicality: Designed for Accessories and Light Towing

Whether you’re adding a drawbar for towing a small trailer or attaching a cargo carrier for extra space on a trip, this hitch is ready to adapt. Drawbar, pin, and clip are sold separately, letting you choose only what you actually need for your setup. It’s an easy way to add flexibility and capability without changing how your vehicle drives day to day.

@Jim Thank you so much, we appreciate your business!!


by:

Hitch was delivered to the wrong address. Not a strainer issue but UPS.

I haven’t opened the box.



by:

As per other discussions and reviews, the slotted mounting holes don't exactly line up on a 2014 Model. I was hoping Curt MFG would have fixed this minor flaw since its release, but it doesn't seem they have addressed the issue. However, with a little TLC, it fits and looks great!



by:

Had to grind the holes bigger with a die grinder as the holes didn't line up. Looking online that seems like a common problem with this hitch. Other than that its been perfect for what I need. It looks great, finish is great and works well. Do have to trim a little bit of the plastic but it isn't noticeable.



by:

Excellent hitch in both construction and fit. This worked very well for my car and application. The installation instructions and videos made it easy to install.



by:

etrailer’s customer service was on point as usual; very good. I did run into a couple challenges with the hitch. There are 8 bolts that hold the hitch to the chassis on the car. The slots in the hitch was really too wide and three of the 8 bolts couldn’t be installed without elongating them. That added a lot of time to the install, trip to the hardware store and for paint to dry. Given the randomness of only three bolts not lining up makes me think the hitch wasn’t built as Curt intended. Don’t know.

The bumper reinstall was a bit challenging due to the thickness from the receiver making for a very tight squeeze with the foam and bumper. It was achieved but not easily. The foam should be trimmed. That said, I don’t have any suggestions there.

Once installed the hitch is in a perfect location and looks decent. This installation is one a GS350 F sport package. No problems there. Since this car is no longer in production, and it’s relatively scarce I was just happy to have an option to be able to haul bikes.



by:

Fit my vehicle perfectly. Does not stick out too far, which is what I was hoping. Just enough for the bike rack to fit on it.

Its pretty close to the ground, which makes the knob on the big rack rub the ground on bumps and driveways, even when going slowly. That being said it is the ONLY hitch option for a Lexus GS350 and it has been holding my rack and E-bikes very well.



by:

Great communication and help! Thank you etrailer!



by:

Outside holes lined up inside didn't Had to open up 4 slots.
Dimension for cut out wrong length to long, width cut borderline.
Not sure if foam needed to be cut to make up for thickness of hitch plate.
Clear and Easy to follow instructions.
Looks good nice fit when done.

The foam should not be trimmed any manner and just reinstalled like the hitch isn’t there.



by:

This item works perfectly. The only thing is that one of the holes doesn't aligns correctly and it took me a while of wrestling with it to make it fit.

After one year my hitch is in pristine conditions, and we all know how extreme is Florida weather!!!



by:

IDK why it is so hard to drill holes, especially SLOTS, to mount a hitch. Had to take another 10+mm of material off one side of the mounting plate holes. If you are capable, no problem. If not, something to consider.



by:

The hitch itself is a good hitch. Unfortunately, the holes in the hitch where the hitch attaches to the car didn't line up well. I had to drill and expand slots in the hitch. After that, all good.



by:

Hitch looks and feels good. I did the installation myself and it went fairly well. The installation took me about 120 minutes to complete. I’m giving this hitch a 4-star review because, as other reviewers have also reported, I had to elongate two out of the eight mounting holes to get the hitch to line up with the Lexus bumper mounting holes and bolts.

See what our Experts say about this CURT Trailer Hitch

  • Trailer Hitch for 2015 Lexus GS 350
    We do not have any hitches to fit the 2015 Lexus GS 350 F-Sport. This trim level would require so much modification that hitch makers determined customers would not accept the result. Curt Class I hitch # C11366, the only option for the car, is excluded as a fit for the F-Sport version for this reason. This hitch installation is fairly challenging even on compatible vehicles. We do offer roof racks for your car that are shown on the linked page.

    The Draw-Tite Class II trailer hitch # 36535 has been discontinued but is a fit for your 2013 Lexus GS 350.
