The 09 - 20 Ford Flex With dual exhaust 2in. CURT Trailer Hitch + Ball Mount + Cover + Lock Kit HWA933 (Part #HWA933) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the Curt 13110 is designed for Ford Flex, Flex Ecoboost, and Lincoln MKT models. The installation process is the same for all three, but note that Ford Flex Ecoboost and Lincoln MKT models have dual exhaust, so the installation steps must be repeated on both the driver and passenger sides.
No, drilling is not required. The hitch uses existing weld nuts on the vehicle and aligns with existing slots. The manual explicitly states 'NO DRILL' as an installation note.
You will need: a ratchet, 10" extension, 18mm and 19mm sockets, and a torque wrench. These tools are needed to remove the rubber isolators, remove the muffler hanger bracket, and torque the M12 fasteners to specification.
The kit includes 4 M12-1.75 x 40mm hex bolts and 4 conical toothed washers (1/2" size). These fasteners are used to secure the hitch to the existing weld nuts on the vehicle. The muffler hanger bracket bolts that you remove during installation should be returned to the vehicle owner.
The first step is to lower the exhaust by removing 3 rubber isolators. Support the exhaust as needed to prevent damage. A rubber isolator removal diagram is provided in the manual to guide this process.
Yes. Remove the muffler hanger bracket by removing its bolts (2 bolts). Keep these bolts and return them to the vehicle owner. On the driver side, the hanger bracket is then sandwiched between the hitch and the exhaust during final assembly.
Rotate the hitch into position above the exhaust and align the slots in the hitch with the existing weld nuts on the vehicle. The hitch uses these factory weld nuts for attachment, so proper alignment is essential before fastening.
The passenger side is secured using the existing weld nuts on the vehicle, along with the M12 hex head bolts and 1/2" conical toothed washers provided in the kit. All M12 fasteners are then torqued to 86 ft. lbs.
The driver side is sandwiched with the muffler hanger bracket and secured using the M12 hex head bolts and 1/2" conical toothed washers provided. The muffler hanger bracket sits between the hitch and the exhaust. All M12 fasteners are then torqued to 86 ft. lbs.
All M12 fasteners must be torqued to 86 ft. lbs. This applies to all four M12 hex head bolts used to secure the hitch.
The hitch weight is 85 lbs.
Professional installation takes approximately 39 minutes. DIY installation for a novice takes approximately 40 minutes.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing inspection helps maintain the integrity and safety of the installation.
Alteration to, misuse of, or improper installation of the hitch voids the warranty. The warranty covers defects in material and workmanship at the time of retail purchase by the original purchaser. If a defect is found, Curt Manufacturing will repair or replace the product at their option.
Yes. When lowering the exhaust by removing the rubber isolators, you must support the exhaust as needed to prevent damage. Failure to do so could result in damage to the exhaust system.
After all M12 fasteners are torqued to 86 ft. lbs., raise the exhaust back into position. This completes the installation process.
No, the installation steps are the same for all three models (Ford Flex, Flex Ecoboost, and Lincoln MKT). However, because Ford Flex Ecoboost and Lincoln MKT models have dual exhaust, you must repeat the installation instructions for both the driver and passenger sides.
