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 (excludes F Sport; 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.

The CURT 13515 Class 3 Trailer Hitch, 2-Inch Receiver, Fits Select Lexus RX350, RX450h (Part #BKDK13515) fits 2016-2022 Lexus RX350 models. The 2022 model year is the last year covered by this part number. For newer models, check for an updated version.
The CURT 13515 Class 3 Trailer Hitch, 2-Inch Receiver, Fits Select Lexus RX350, RX450h (Part #BKDK13515) Drilling is not required for installation. Typical installation time is 60-90 minutes. Basic hand tools are typically all you need.
The CURT 13515 has a gross trailer weight (GTW) capacity of 3,500 lbs and a tongue weight (TW) capacity of 525 lbs. For weight distribution towing, the capacity is 4,000 lbs GTW with 525 lbs tongue weight. Never exceed your vehicle manufacturer's recommended towing capacity.
The CURT 13515 is designed for both hybrid and non-hybrid models, but the installation procedure differs between them. Hybrid models require removal of the underbody panel and lowering of the exhaust; non-hybrid models skip these steps. Refer to the installation steps for your specific model type.
Required tools: ratchet, reciprocating saw or hacksaw, sockets (10mm, 12mm, 17mm, 19mm), socket extension, flathead screwdriver, torque wrench, tape, and marker. Safety glasses must be worn at all times during installation. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
No drilling is required. The CURT 13515 uses existing vehicle frame weldnuts for mounting. However, trimming of the underbody panel and fascia is required using a reciprocating saw or hacksaw.
For non-hybrid models, a 3" × 3" area of the lower fascia must be trimmed at the center line of the bottom edge using a reciprocating saw or hacksaw. For hybrid models, the underbody panel must be removed and both underbody panels trimmed according to the trim diagram (7-1/2" × 8" and 4" areas). Do not cut on the sensor bracket.
All M12 bolts must be torqued to 79 ft-lbs.
All M8 bolts on hybrid models (used to secure the exhaust bracket) must be torqued to 16 ft-lbs.
Safety glasses must be worn at all times during installation. Use caution when trimming lower fascia and underbody panels. Do not cut on the sensor bracket. After installation, perform periodic inspection to ensure all mounting hardware remains tight and structural components are secure.
The CURT 13515 package includes: 1 trailer hitch, 4 hex bolts (M12 × 1.25"), 2 hex nuts (M8 × 1.25"), 2 conical-toothed washers (3/8"), and 4 conical-toothed washers (1/2").
The manual notes that model year 2021 and later vehicles may have sensor bracket tabs that must be removed before installation. For model year 2021 and earlier, this step is not required. Consult the manual or contact CURT product support at 877-287-8634 to confirm compatibility with your specific vehicle.
No. Underbody panel removal is required only for hybrid models. Non-hybrid models skip this step and proceed directly to removing the tie-down bracket. For hybrid models, the underbody panel is secured by 14 fasteners (10mm socket) and one push fastener in the wheel well trim.
The tie-down bracket is located on the passenger side and is secured by two bolts (17mm socket). It must be removed during installation and returned to the vehicle owner. The hitch does not use this bracket.
The vehicle weldnuts are located behind plastic caps on the driver-side frame rail. Remove the two rear-most plastic caps using a flathead screwdriver to gain access to the existing vehicle weldnuts. Clean any debris from the weldnuts using lubricant, compressed air, or a wire brush, taking care not to damage the threads.
Spray lubricant or compressed air into the weldnut hole to remove debris. For heavy debris, use a wire brush. Take care not to damage the threads.
The hitch is secured using the existing vehicle weldnuts on both sides, plus two M12 bolts and 1/2" conical washers on each side. The conical washers must be oriented correctly with the toothed side facing the frame. All M12 hardware must be torqued to 79 ft-lbs.
The conical-toothed washers must be oriented with the toothed side facing the vehicle frame. The manual includes a diagram showing the correct orientation on page 2.
For hybrid models: (1) Remove the underbody panel (14 fasteners, 10mm socket); (2) Remove the tie-down bracket (2 bolts, 17mm socket); (3) Remove plastic caps on driver-side frame rail (flathead screwdriver); (4) Remove sensor bracket tabs if present (model year 2021+); (5) Trim 3" × 3" fascia area; (6) Lower the exhaust (2 M8 bolts, 12mm socket); (7) Raise and secure hitch with weldnuts, M12 bolts, and 1/2" conical washers; (8) Torque M12 hardware to 79 ft-lbs; (9) Raise exhaust and secure with M8 bolts, 3/8" conical washers, and M8 nuts; (10) Torque M8 hardware to 16 ft-lbs; (11) Trim underbody panels; (12) Reinstall underbody panel.
For non-hybrid models: (1) Remove the tie-down bracket (2 bolts, 17mm socket); (2) Remove plastic caps on driver-side frame rail (flathead screwdriver); (3) Trim 3" × 3" fascia area at center line of bottom edge; (4) Raise and secure hitch with weldnuts, M12 bolts, and 1/2" conical washers; (5) Torque M12 hardware to 79 ft-lbs.
Yes. On hybrid models, the exhaust must be lowered by removing two M8 bolts from the bracket on the passenger side (12mm socket) before raising the hitch. After the hitch is secured, the exhaust is raised back into position and secured with the same M8 bolts, 3/8" conical washers, and M8 hex nuts, then torqued to 16 ft-lbs.
Slight bending or modification to the exhaust heat shield may be needed to avoid contact with the hitch. This should be assessed during installation.
Slide the rear part of the panel into place first to ease reinstallation. Secure using all fourteen fasteners that were removed during the initial removal step. Use a 10mm socket.
The hitch uses: 4 hex bolts (M12 × 1.25"), 2 hex nuts (M8 × 1.25"), 2 conical-toothed washers (3/8"), and 4 conical-toothed washers (1/2"). M12 bolts are torqued to 79 ft-lbs; M8 bolts are torqued to 16 ft-lbs (hybrid models only).
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. To help prevent damage to the product or vehicle, refer to the specified torque specifications when securing hardware.
