All Hardware and Installation Instructions Included!
However you define adventure -- whether it's climbing onto the back of a mountain bike, hunting from the top of a tree stand or camping with the family a long way from nowhere -- CURT class 1 hitches provide a light-duty towing receiver to help you Bring It. Each is made to fit a specific vehicle, providing easier installation, a better fit and optimal towing capacity. Custom class 1 trailer hitches are available for a variety of smaller vehicle types, including the compact car, crossover, minivan and small SUV. This particular class 1 hitch is designed to be a custom hitch for certain years of the Chevy Cobalt and Pontiac Pursuit (to verify vehicle compatibility, see the CURT application guide at curtmfg.com). Tested in accordance with SAE J684, it offers a weight carrying capacity of 2,000 lbs. GTW and 200 lbs. TW. It is equipped with 1-1/4" receiver tube opening to accept a ball mount shank or other hitch mount. This class 1 hitch also comes with all necessary mounting hardware. With its lightweight design and smaller receiver tube size, a class 1 hitch is especially useful for adding cargo space with a hitch-mounted bike rack or cargo carrier. They can also typically be used to tow small trailers such as a utility trailer, kayak trailer or teardrop camper (never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Though CURT class 1 trailer hitches are only intended for light-duty towing, we apply the same principles of quality as we do to the rest of our rear mount hitches. Each class 1 hitch is made with hands-on engineering, high-strength steel and precise welding. We use a co-cured finish of liquid A-coat, inside and out, and durable black powder coat to provide a lasting defense against rust, chips and UV rays.
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 Chevy Cobalt, Pontiac G5 and Pontiac Pursuit sedan (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.

The Curt 11430 is designed for use with ball mount #D-21 / 45521. Use only this specified ball mount to ensure proper fitment and safety.
The kit includes: 4× carriage bolts (1/2-13 UNC, 1-1/4", Grade 8), 2× square hole spacers (0.250 × 1.50 × 4.00"), 6× serrated flange nuts (1/2-13 UNC, Grade 8), 2× hex head cap screws (1/2-13 UNC, 1-1/2", Grade 8), 2× flat washers (1/2"), and 2× square hole spacers (0.250 × 1.50 × 3.00"). All fasteners are Grade 8 zinc-plated steel.
You will need: a 1/2" drill bit, a center punch, a torque wrench capable of 110 lb-ft, a wrench or socket set for 1/2" fasteners, and silicone sealant. A drill press or hand drill is required to drill four holes in the bumper beam and two holes in the trunk pan.
Yes. You must temporarily remove the trunk pan cover and move the battery away from the trunk pan wall to provide clearance for drilling. The battery and trunk pan cover are reinstalled after the hitch installation is complete.
Yes. The rear air dam must be removed during installation and returned to the vehicle owner after the hitch is installed. It is not permanently modified or discarded.
Yes. Drilling is required. You must drill four 1/2" holes in the bumper beam and two 1/2" holes in the trunk pan. The holes are marked and center-punched before drilling to ensure accurate placement.
A 1/2" drill bit is required. This size is used for all six holes: four in the bumper beam and two in the trunk pan.
Locate and mark the center of the vehicle on the bumper beam. Position the hitch on the vehicle center, ensuring the back of the side plates sit flat against the trunk pan. Mark and center punch the four holes in the bumper beam while the hitch is centered in this position.
Four carriage bolts (1/2-13 UNC, 1-1/4", Grade 8) secure the hitch to the bumper beam. Each bolt is installed with a 0.250 × 1.50 × 4.00" square hole spacer and a serrated flange nut (1/2-13 UNC, Grade 8).
Two hex head cap screws (1/2-13 UNC, 1-1/2", Grade 8) secure the hitch to the trunk pan. Each screw is installed with a flat washer (1/2"), a 0.250 × 1.50 × 3.00" square hole spacer, and a serrated flange nut (1/2-13 UNC, Grade 8).
Yes. After drilling the two holes in the trunk pan and installing the fasteners, you must seal the holes with silicone to prevent water and debris from entering the trunk.
All 1/2" fasteners must be torqued to 110 lb-ft. This applies to all six fasteners: the four carriage bolts in the bumper beam and the two hex head cap screws in the trunk pan.
The manual does not specify the gross load capacity or tongue weight rating for this hitch. You must not exceed your vehicle manufacturer's recommended towing capacity. Contact Curt Technical Support at 877-287-8634 or consult your vehicle's owner manual for the correct limits.
Non-trailer loads (such as cargo carriers or roof racks attached to the hitch) are not recommended without additional support. If you do carry non-trailer loads, they must be supported by auxiliary stabilizing straps. Failure to properly support non-trailer loads will void the product warranty.
Periodically check the hitch to ensure that all fasteners are tight and that all structural components are sound. No specific interval is stated in the manual. If you notice any loose fasteners or damage, tighten or repair them immediately before using the hitch.

Yes, Curt part 55434 is designed for Chevrolet Cobalt 4-door models, including the Cobalt SS 4-door. It is also compatible with Pontiac G5 Pursuit 4-door and G5 Pursuit GT 4-door models. This harness is specifically for 4-door vehicles only.
No. Curt part 55434 is designed only for 4-door models. The manual specifies Chevrolet Cobalt (4DR), Chevrolet Cobalt SS (4DR), Pontiac G5 Pursuit (4DR), and Pontiac G5 Pursuit GT (4DR). Two-door versions are not listed as compatible.
Yes. The installation requires removal of both taillight assemblies. You must remove plastic wing nuts inside the trunk on each side, pull back the carpet to access a second set of wing nuts, then remove taillight screws located outside the vehicle next to the trunk weather seal using a 9/32" socket. Handle the assemblies carefully to avoid damaging the alignment pins, and unplug the taillight connectors before setting them aside.
You will need a 9/32" socket to remove the taillight screws. If a suitable grounding point does not already exist on the vehicle frame, you will need a drill to create a 3/32" hole for the white wire ground connection. The manual provides an eyelet and screw for securing the ground wire.
The harness includes a T-connector with yellow and green wire ends. On the driver's side, plug the T-connector end with the yellow wire between the separated connectors, ensuring the connectors are fully inserted with the locking tabs in place. Route the T-connector end with the green wire down through the opening below the taillight, across the bumper, and up through the opening on the passenger's side. Repeat the connection process on the passenger side using the green wire connector.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no suitable point exists, drill a 3/32" hole and secure the white wire using the eyelet and screw provided with the harness. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
The ground wire is white. It should be secured to a suitable grounding point on the vehicle's frame using either an existing screw with nut or a new 3/32" hole with the provided eyelet and screw.
After connecting the T-connectors at both taillights, route the 4-flat connector to the center of the vehicle and secure it in a convenient, out-of-the-way location. Secure any loose wires using the cable ties provided with the harness.
Before drilling any hole, verify that miscellaneous items are not hidden behind or under any surface. Drilling without checking could cause damage to hidden components and result in personal injury.
If you need to drill a new grounding point, the hole size is 3/32". The harness includes an eyelet and screw to secure the white ground wire in this hole.
A 9/32" socket is required to remove the taillight screws located outside the vehicle next to the trunk weather seal.
When removing the taillight assemblies, handle them carefully to avoid damaging the alignment pins. After removing the screws and assemblies, unplug the taillight connectors before setting them aside.
You must remove two sets of plastic wing nuts. First, remove one plastic wing nut on each side of the trunk located behind the taillights. Then carefully pull back the carpet on both sides to expose and remove the second set of plastic wing nuts. Set all wing nuts aside.
When plugging the T-connector between the separated connectors, make sure the connectors are fully inserted with the locking tabs in place. This applies to both the yellow wire connector on the driver's side and the green wire connector on the passenger's side.
Curt 55434 fits 4-door Chevrolet Cobalt, Cobalt SS, Pontiac G5 Pursuit, and G5 Pursuit GT models only.
You need a 9/32" socket to remove taillight screws. A drill with 3/32" bit may be needed if you must create a new ground point on the frame.
Yes. You must remove both taillight assemblies by removing plastic wing nuts inside the trunk and taillight screws outside the vehicle, then unplug the connectors.
The ground wire is white. It connects to a frame grounding point using either an existing screw or a new 3/32" hole with the provided eyelet and screw.
Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
