No. The Curt 13551 receiver hitch is designed for Ford Flex vehicles but explicitly excludes EcoBoost models. If you have a Ford Flex with an EcoBoost engine, this hitch is not compatible.
The Curt 13551 has a gross load capacity of 5,000 lbs trailer weight and 500 lbs tongue weight when used as a weight-carrying hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these figures.
You will need: a drill with a 1-1/4" bit, a ratchet, a 10" extension, an 18mm socket, a 19mm socket, and a torque wrench. The torque wrench is essential because fasteners must be torqued to specific values (110 lb-ft for 1/2" bolts and 79 lb-ft for M12 fasteners).
Yes. The installation requires lowering the muffler brackets. The muffler brackets will be positioned between the frame and hitch bracket during installation. The M12 bolts on the forward edge of the muffler bracket on each side must be removed first and then re-installed after the hitch is in position.
Yes, drilling is required. You must drill a 1-1/4" access hole in the frame on each side (both driver and passenger sides), positioned approximately halfway between the existing M12 weldnut and the existing hole. This is a permanent modification to the vehicle frame.
Fishwire is used to route the 1/2" carriage bolts and spacers through the access holes you drill in the frame and out through the existing holes. The fishwires remain attached to the bolts and are then threaded through the hitch bracket to pull the bolts into position. This allows you to route the fasteners through the frame without direct access.
The kit includes: 2× 1/2-13 UNC grade 8 carriage bolts (1-3/4" long), 2× 0.250 x 1.00 x 3.00" square hole spacers, 2× 1/2" fishwire, 2× 1/2-13 UNC grade 8 serrated flange nuts, 1× M12x1.75 class 10.9 hex cap screw (30mm), 1× 1/2" S-con washer, and 1× 0.250 x 1.50 x 2.00" square hole spacer. The M12 bolts from the muffler bracket are reused.
Yes. The M12 bolts removed from the forward edge of the muffler bracket in step 1 must be saved and re-installed in step 5 after the hitch is positioned. Do not discard these bolts.
All 1/2" bolts must be torqued to 110 lb-ft. All M12 fasteners must be torqued to 79 lb-ft. Hand-tighten all fasteners first, then apply final torque values using a torque wrench.
1. Remove the M12 bolts from the forward edge of the muffler bracket on each side (save these bolts). 2. Drill a 1-1/4" access hole in the frame on each side, approximately halfway between the M12 weldnut and existing hole. 3. Fishwire the 1/2" carriage bolts and spacers through the access holes and out the existing holes, leaving fishwires attached. 4. Raise the hitch into position against the frame with muffler brackets between frame and hitch. 5. Thread fishwires through the hitch and install 1/2" flange nuts; re-install the M12 bolts. Hand-tighten all fasteners. 6. Torque 1/2" bolts to 110 lb-ft and M12 fasteners to 79 lb-ft.
If the vehicle has a single exhaust, the passenger side uses items 5, 6, and 7 from the parts list in place of the bracket. These are: a 1/2" S-con washer (item 5), a 0.250 x 1.50 x 2.00" square hole spacer (item 6), and a 0.250 x 1.50 x 2.00" square hole spacer (item 7).
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This ongoing inspection helps maintain safe operation and prevents loosening of critical fasteners.

Yes. You must drill two 1-1/4" access holes in the frame (one on each side). A drill with a 1-1/4" bit is required.
The hitch supports 5,000 lbs trailer weight and 500 lbs tongue weight, but you must not exceed your vehicle manufacturer's recommended towing capacity.
Torque all 1/2" bolts to 110 lb-ft and all M12 fasteners to 79 lb-ft. A torque wrench is required.
You need a drill with 1-1/4" bit, ratchet, 10" extension, 18mm socket, 19mm socket, and torque wrench.
