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 RX350 and RX450h (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,000 lbs. GTW and 600 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 5,000 lbs. WD and 600 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.
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Lexus RX350 and RX450h (factory tow package required; to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

The part number is 13143. This hitch is designed for Lexus RX 350 (including F Sport) and RX 450H models from 2010–2015.
Yes, part number 13143 fits Lexus RX 350 F Sport models from 2010–2015. F Sport models require additional installation steps including placement of a support plate under the passenger side plate and relocation of the support bar, which will be rotated upside down from its original position.
Yes, part number 13143 is designed for Lexus RX 450H models from 2010–2015.
When used as a weight-carrying hitch, the gross load capacity is 4,000 lbs. trailer weight and 600 lbs. tongue weight. When used as a weight-distribution hitch, the gross load capacity is 5,000 lbs. trailer weight and 600 lbs. tongue weight. Do not exceed your vehicle manufacturer's recommended towing capacity.
The hitch weight is 35 lbs.
The hitch includes 6 M12 – 1.25 x 40 hex bolts and 6 conical toothed washers (1/2"). The hitch uses existing weldnuts in the frame rails (3 each side) and existing hole plugs. For F Sport models, the support bar is reattached using existing nuts removed from the tow loops.
Required tools are: ratchet, torque wrench, 9-inch socket extension, 10mm socket, 17mm socket, 19mm socket, screwdriver (flat head), and aviation shears. A rotary tool may be used as an alternative to aviation shears for trimming the fascia. Safety glasses must be worn at all times during installation.
No, drilling is not required. The hitch uses existing weldnuts in the frame rails and existing hole plugs.
Yes, trimming is required. The underbody panel and lower fascia must be trimmed to accommodate the hitch and support bar (on F Sport models). Use masking tape to layout the trim area, then use a rotary tool or aviation shears to trim. The fascia trim area is 4.50 inches wide by 6.00 inches tall. Consult the vehicle owner prior to trimming.
Two people may be required to ease installation. The manual recommends reading all instructions thoroughly before beginning and notes that using proper tools will greatly improve the quality of the install and reduce the time required.
Professional installation time is approximately 70 minutes. Novice (DIY) installation time is approximately 38 minutes. Actual time may vary depending on experience and familiarity with the vehicle.
All 12mm fasteners must be torqued to 86 ft-lbs. This applies to the M12 – 1.25 x 40 hex bolts that secure the hitch to the frame rail weldnuts.
Tow loop reattachment is optional on non-F Sport models. However, tow loops cannot be reattached on F Sport models. The existing tow loop fasteners are removed during installation and should be returned to the vehicle owner.
On F Sport models, the support plate is placed under the passenger side plate. The hitch is clamped between the frame and the support plate. The support bar is then attached to the hitch and support plate using existing nuts removed from the tow loops.
The support bar is rotated upside down (180 degrees) from how it was originally attached to the tow loops. It is then attached to the hitch and support plate using the existing nuts that were removed from the tow loops.
The exhaust may need to be temporarily lowered to ease installation. If lowered, the exhaust must be supported as needed to prevent damage. The exhaust should be reinstalled after the hitch is secured in position.
The installation sequence is: (1) remove lower fascia by removing 13 fasteners; (2) temporarily lower exhaust if needed; (3) remove existing hole plugs from frame rails; (4) on F Sport models, remove support bar by removing four nuts; (5) remove existing tow loop fasteners and tow loops; (6) raise hitch into position, aligning with existing weldnuts; (7) secure hitch with 12mm bolts and 1/2" conical toothed washers; (8) on F Sport models, attach support bar using existing nuts; (9) torque all 12mm fasteners to 86 ft-lbs; (10) reinstall exhaust if lowered; (11) trim fascia as needed and reattach.
After installation, verify that the fascia fits properly and has adequate clearance. Periodically check that all fasteners are tight and that all structural components are sound. Do not exceed your vehicle manufacturer's recommended towing capacity.
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 inspection interval, but regular checks are recommended to maintain safe operation.

The hitch itself supports up to 4,000 lbs. trailer weight and 600 lbs. tongue weight as a weight-carrying hitch, or 5,000 lbs. trailer weight and 600 lbs. tongue weight as a weight-distribution hitch, but your vehicle's manufacturer specifications take precedence.

If the fascia does not fit properly after trimming, trim further as needed and try again. The fascia trim area should be approximately 4.50 inches wide by 6.00 inches tall. Check for proper fit and clearance before reattaching the fascia using the existing hardware.
Ensure the hitch plates are properly aligned with the existing weldnuts in the frame rails. Start with the passenger side plate and pull down on the exhaust to create clearance.
