Yes, Curt part number 12231 is designed for 2001–2006 Lexus LS 430 Sedan models. Do not use this hitch on other Lexus models or body styles without confirming compatibility with Curt Manufacturing.
Curt hitch 12231 is designed for use with ball mount D-55010. Use only this ball mount or confirm compatibility with Curt Manufacturing before using a different mount.
The hitch includes 6 M12×1.25 hex head cap screws (part 10-10277), 6 lock washers 1/2" (part 30-00153), and 6 flat washers 7/16" (part 30-00166). These fasteners are used to mount the hitch to the existing exhaust bracket mounting points.
You will need a torque wrench capable of tightening to 86 lb-ft, and a socket or wrench to fit M12 fasteners. A jack or lift may be helpful to access the rear undercarriage, though the manual does not specify this as required.
No. The manual states "NO DRILLING REQUIRED." The hitch uses existing exhaust bracket mounting points on the Lexus LS 430 chassis.
The manual diagram labels the spare tire well on both driver and passenger sides, indicating the hitch design accounts for spare tire location. However, the manual does not explicitly state whether clearance is maintained. Verify clearance visually after installation or contact Curt Manufacturing if you have concerns.
1. Locate the exhaust mufflers at the left and right rear of the vehicle. Each muffler is supported by flexible supports and brackets bolted to the chassis with three 12 mm screws per bracket. 2. Temporarily remove these brackets from the chassis on both sides. 3. Position the hitch at these same mounting points. 4. Re-mount the exhaust brackets at the bottom of the hitch brackets on both sides using the fasteners provided (M12×1.25 hex head cap screws with lock and flat washers). 5. Torque all fasteners to 86 lb-ft.
Torque all M12 fasteners to 86 lb-ft.
The manual does not provide specific towing capacity, trailer weight capacity, or tongue weight capacity values—these fields are blank in the parts list. Do not exceed your vehicle manufacturer's recommended towing capacity. Contact Curt Manufacturing or your Lexus dealer for the specific capacity ratings for your hitch.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. Re-torque fasteners as needed to maintain 86 lb-ft.
Yes. Alteration to, misuse of, or improper installation of this product voids the warranty. Curt Manufacturing's liability is limited to repair or replacement of defective products and excludes liability for incidental or consequential loss or damage.
Yes, it fits 2001–2006 Lexus LS 430 Sedan models only.
