All Hardware and Installation Instructions Included!
Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Lexus NX200t, NX300 and NX300h (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 3,500 lbs. GTW and 525 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 4,000 lbs. WD and 525 lbs. WDTW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.
If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Lexus NX200t, NX300, and NX300h (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Yes, CURT part number 13337 is designed for Lexus NX200t and NX300h models from 2015 to present. The hitch is a weight-carrying receiver hitch rated for 3500 lbs trailer weight and 525 lbs tongue weight, or 4000 lbs trailer weight and 525 lbs tongue weight when used as a weight distribution hitch. Always verify your specific model year and confirm the hitch matches your vehicle before installation.
The CURT 13337 has two rated capacities depending on how it is used. As a weight-carrying hitch, it supports 3500 lbs trailer weight and 525 lbs tongue weight. As a weight distribution hitch, it supports 4000 lbs trailer weight and 525 lbs tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these ratings.
The hitch weight is 40 lbs.
You will need a ratchet, a torque wrench, a 19mm socket, and safety glasses. No drilling is required for this installation.
The hitch includes 4 M12x1.25 hex cap screws (part number 10-10275) and 4 conical washers (part number 30-00149). These fasteners attach the hitch to the existing weldnuts on both frame rails.
You must lower the exhaust by removing the 3 rearmost rubber exhaust isolators. Support the exhaust during removal to prevent damage. After the hitch is installed and torqued, you will raise the exhaust and reinstall the rubber isolators. You do not need to completely remove the exhaust system.
Two people may be required to ease installation. While one person may be able to complete the installation, having a second person will help, particularly when lowering and raising the exhaust and positioning the hitch.
Follow these steps: (1) Lower the exhaust by removing the 3 rearmost rubber exhaust isolators and support the exhaust to prevent damage. (2) Raise the hitch into position and loosely secure it with M12 bolts and conical washers. (3) Torque all M12 fasteners to 60 ft-lbs. (4) Raise the exhaust and reinstall the rubber isolators.
All M12 fasteners must be torqued to 60 ft-lbs. Use a torque wrench with a 19mm socket to achieve the correct torque value.
No. When you first raise the hitch into position, loosely secure it with the M12 bolts and conical washers. Only after the hitch is properly positioned should you torque all M12 fasteners to 60 ft-lbs.
The manual indicates weldnut cleaning as part of the installation process, but does not provide specific cleaning instructions or requirements. Contact CURT technical support at 1-877-287-8634 for guidance on weldnut preparation.
No drilling is required. The hitch uses existing weldnuts on both frame rails. The only modification is temporarily lowering the exhaust by removing the 3 rearmost rubber exhaust isolators, which are reinstalled after the hitch is secured. No permanent modifications to the vehicle are necessary.
Safety glasses must be worn at all times during installation. Support the exhaust during removal of the rubber isolators to prevent damage. Read all instructions thoroughly before beginning installation. If you are hesitant to undertake this task, contact an authorized CURT installer for assistance.
After installation, verify that all M12 fasteners are torqued to 60 ft-lbs and that the exhaust isolators are properly reinstalled. Periodically check the receiver hitch to ensure that all fasteners remain tight and that all structural components are sound.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify an exact interval, but regular inspection before towing is recommended.

Yes. The first step of installation is to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal. This must be done before any other work.
You must remove: all trunk floor coverings, fasteners securing the trunk storage trays, all storage trays, the spare tire cover, and the spare tire. You will also need to remove the scuff panel and cargo tie downs from the side trim panels.
The custom wiring harness end with the yellow wire connects on the driver side. It is inserted between the separated taillight housing connectors, behind the removed side trim panel. Make sure the connectors are fully inserted with locking tabs in place.
The custom wiring harness end with the green wire connects on the passenger side. It is routed behind the removed scuff panel and inserted between the separated taillight housing connectors, following the same procedure as the driver side (steps 4–6).
Drilling may be required for the ground wire. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, you may drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint. Always check for hidden items before drilling to avoid damage and personal injury.
Drill a 3/32" pilot hole if a suitable existing grounding point is not available. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
The black converter box should be adhered to a flat spot inside the vehicle near the taillight using the provided double-sided tape.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
When in use, route the 4-flat to the center of the vehicle. When not in use, roll it up and store in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties. Install the provided 4-flat dust cover to help prevent corrosion.
All steps must be followed to ensure the wiring harness functions properly. Once installed, test for proper function by using a test light or connecting a properly wired trailer. Reconnect the negative battery terminal and reinstall all items removed during installation before testing.
When removing the scuff panel, pull out on the bottom and then up. Take care not to damage the alignment tabs located on the back of the panel.
When separating the taillight housing connectors, take care not to damage the locking tabs. The custom wiring harness connectors will be similar to the vehicle's taillight connectors.
