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 Dodge D100 Pickup, D150, D200 Pickup, D250, D300 Pickup or D350 and Ford Bronco, F100, F150, F250 or F350 (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 6,000 lbs. GTW and 600 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 10,000 lbs. WD and 1,000 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.
If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Dodge Ram 1500, 2500, 3500 and Dakota (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Yes, part 13310 fits 1973–1997 Ford F-Series trucks, with one exception: it does not fit 1973–1979 F-250 crew cab models. If your truck is a regular cab, supercab, or 1980 or later F-250, this hitch is compatible.
Yes, the Curt 13310 is compatible with 1978–1997 Ford Bronco Full Size models.
Yes, the Curt 13310 fits 1967–2002 Dodge Full Size trucks.
On 1973–1997 Ford F-Series trucks (except 73–79 crew cab), the spare tire must be lowered before installation. The installation notes specify "LOWER SPARE TIRE" as part of the setup. After installation is complete, the spare tire can be repositioned if necessary.
On 1978–1997 Ford Bronco Full Size models, the bumper may interfere with the hitch. If it does, the bumper bolts can be loosened and the bumper raised to increase clearance. After adjustment, re-tighten the bolts.
On 1967–2002 Dodge Full Size trucks, the bumper may interfere with the receiver hitch. If interference occurs, loosen the bumper brackets and reposition the bumper upward, then re-tighten the brackets.
The kit includes: 6× 1/2–13 UNC carriage bolts, 1–3/4″ length, grade 8 (part 10-10272); 8× 0.250 × 1.50 × 2.00″ square hole spacers (part CM-SP1); and 6× 1/2–13 UNC serrated flange nuts, grade 8 (part 20-00062).
No, all required fasteners are included: 6 carriage bolts, 8 spacers, and 6 flange nuts. The spacers are essential—the manual specifies that a spacer must be placed at the large middle mounting hole on both sides of the hitch.
A torque wrench is required to tighten all fasteners to 110 ft-lbs. Drilling equipment is also needed: a drill with bits for 1/8″ pilot holes, 3/8″ intermediate holes, and 1/2″ final holes (on F-Series and Bronco). For Dodge trucks, 1/2″ holes are drilled directly. A thin wire is needed for the Bronco installation to fishwire the forward bolts through the frame.
The manual does not mention battery disconnection. No electrical work is involved in this installation.
The manual does not require bumper removal for F-Series installation. However, on Ford Bronco and Dodge trucks, bumper bolts may need to be loosened and the bumper raised to provide clearance for the hitch.
Yes, drilling is required. The manual specifies the step method: first drill a 1/8″ pilot hole, then a 3/8″ hole, and finally a 1/2″ hole. Six 1/2″ mounting holes must be drilled. On some models, the hitch's 9/16″ slots may align with existing 1/4″ holes in the frame; if so, drill these out to 1/2″.
Yes, six 1/2″ holes must be drilled. The manual notes to take extra care around the gas tank during drilling.
Drilling may be required. The manual states that mounting locations may need to be drilled on some vehicles. The Dodge installation uses existing 1/2″ round holes at the rear of the frame for the first and third bolts, then the hitch is used as a template to drill the four remaining holes to 1/2″ diameter.
The step method involves three stages: (1) drill a 1/8″ pilot hole, (2) drill a 3/8″ hole, and (3) finish with a 1/2″ hole. This method is used for all six mounting holes on F-Series trucks.
The final hole size is 1/2″ for all vehicles. On F-Series and Bronco, use the step method (1/8″ pilot, then 3/8″, then 1/2″). On Dodge, existing 1/2″ round holes are used where available, and additional 1/2″ holes are drilled as needed.
Yes, the manual states: "TAKE EXTRA CARE AROUND THE GAS TANK." Additionally, because of tight clearance with the gas tank, the two forward holes on each side must be fishwired (bolts wrapped with thin wire and fed through the square hole spacer using the access hole in the crossmember next to the frame).
All fasteners must be tightened to 110 ft-lbs using a torque wrench. This applies to all mounting bolts on all vehicle types.
The carriage bolts are 1/2–13 UNC, 1–3/4″ long, grade 8 (part 10-10272). Six bolts are included.
The spacers are 0.250 × 1.50 × 2.00″ square hole spacers (part CM-SP1). Eight spacers are included. A spacer must be placed at the large middle mounting hole on both sides of the hitch.
The manual does not provide specific towing capacity values. The parts list shows blank fields for gross load capacity (weight carrying and weight distribution). The manual emphasizes: "DO NOT EXCEED VEHICLE MANUFACTURER'S RECOMMENDED TOWING CAPACITY." Contact Curt Manufacturing technical support at 1-877-287-8634 for capacity information.
After installation, periodically check that all fasteners are tight and that all structural components are sound. The manual states: "PERIODICALLY CHECK THIS RECEIVER HITCH TO ENSURE THAT ALL FASTENERS ARE TIGHT AND THAT ALL STRUCTURAL COMPONENTS ARE SOUND."
The manual does not specify a checking interval. It states that you should periodically check the receiver hitch to ensure all fasteners are tight and structural components are sound. No retorque interval is provided.
The Curt 13310 fits 1973–1997 Ford F-Series (except 73–79 crew cab), 1978–1997 Ford Bronco Full Size, and 1967–2002 Dodge Full Size trucks. On F-Series, the spare tire must be lowered. On Bronco and Dodge, the bumper may need repositioning.
The kit includes 6 carriage bolts, 8 spacers, and 6 flange nuts—no additional fasteners needed. A torque wrench is required to tighten all bolts to 110 ft-lbs.
Yes. On Ford F-Series and Bronco, use the step method: 1/8″ pilot hole, then 3/8″, then 1/2″ final holes. On Dodge, existing 1/2″ holes are used where available, and additional 1/2″ holes are drilled as needed. Extra care is required around the gas tank on Bronco.
Tighten all fasteners to 110 ft-lbs using a torque wrench.

Yes, the Curt 55329 is designed for Dodge Dakota pickup trucks. The harness connects to your vehicle's existing taillight wiring connectors and routes a 4-flat connector to the center of the vehicle for trailer use.
Yes, the Curt 55329 is compatible with Dodge Ram 1500 pickup trucks. Installation involves connecting the harness to your vehicle's taillight wiring connectors.
The Curt 55329 is compatible with Dodge Ram 2500 and 3500 pickup trucks, but only if your vehicle has a factory 7-way connector. If your Ram does not have this factory connector, this harness will not be compatible.
The Curt 55329 is a custom wiring harness that integrates with your vehicle's taillight wiring to provide a 4-flat trailer connector. It allows you to connect a trailer to your Dodge pickup truck while using the vehicle's existing lighting system.
1. Locate your vehicle's taillight wiring harness connectors. 2. Carefully separate the connectors from the taillight housing without damaging the locking tabs. 3. Insert the custom harness end with the yellow wire between the separated connectors, ensuring they are fully inserted with locking tabs in place. 4. Route the harness end with the green wire to the passenger side behind the removed scuff panels and repeat steps 1–3 on that side. 5. Route the 4-flat connector to the center of the vehicle and out of the trunk when in use; roll up and store inside the trunk when not in use. 6. Secure loose wires with the provided cable ties. 7. Reinstall all removed items and install the provided 4-flat dust cover.
Yes. During installation, you must remove scuff panels to route the harness end with the green wire to the passenger side. These panels must be reinstalled after the harness is routed.
The yellow wire end of the custom wiring harness is inserted between the separated taillight connectors on the driver side of the vehicle during installation.
The green wire end of the custom wiring harness is routed to the passenger side of the vehicle behind the removed scuff panels and is inserted between the separated taillight connectors on that side.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. When you need to use it, route it to the center of the vehicle and out of the trunk.
The provided cable ties are used to secure any loose wires during installation to keep them organized and prevent them from moving around.
The provided 4-flat dust cover is installed after the harness is fully set up to help prevent corrosion of the 4-flat connector.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Exceeding the rating can cause loss of warranty, overheating, and potential fire. Check your vehicle owner's manual or contact the vehicle manufacturer for your specific lamp load rating.
After installation, test for proper function by using a test light or by connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly.
The connectors are fully inserted when the locking tabs are in place. Take care during insertion to ensure the locking tabs engage properly and the connectors seat completely.
Before drilling or working on any part of the installation, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
