A CURT front trailer hitch allows you to use the front end of your vehicle for a variety of towing applications. They can be used for mounting a winch, a snow plow, a number of towing accessories and can even be used for some trailering applications. When space is limited, a front trailer hitch is commonly used to hold a cargo carrier, freeing up space inside the vehicle for extra cargo and making the rear mount receiver available to pull a trailer. At the boat ramp, your boat trailer can be hitched up to the front receiver hitch, giving you better control over the trailer as you launch. Some of the other accessories that can be used with a front tow hitch are the CURT winch mount, step pad, license plate holder, spare tire mount, skid shield and tow hooks. All CURT front trailer hitches provide a useful receiver tube to accept a 2" x 2" shank, and they are commonly used on trucks, vans and SUVs. This front trailer hitch is rated for 3,500 lbs. GTW and 350 lbs. TW. It also has a straight-line pull rating of 9,000 lbs. It is designed to be a custom trailer hitch for certain years of the Buick Rainier, Chevy Trailblazer and GMC Envoy (to verify your vehicle compatibility, see application info). It comes with all necessary hardware for a complete installation and is backed by a limited lifetime warranty.

The CURT 31055 2-Inch Front Receiver Hitch, Select Buick Rainier, Chevrolet Trailblazer, GMC Envoy (Part #BKDK31055) Drilling is not required for installation. Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
The Curt 31055 is designed for Chevy Trailblazer, GMC Envoy, GMC Denali, and Buick Rainier. Verify your exact vehicle model and year match these applications before purchasing. Visit www.hitchinfo.com for current application coverage.
The manual lists gross load capacity and straight line pull capacity specifications, but the specific weight values are blank in the provided documentation. Contact Curt Manufacturing or visit www.hitchinfo.com for the complete capacity ratings. You must not exceed your vehicle manufacturer's recommended towing capacity.
The hitch requires trimming of the front bumper fascia and underbody panel. If your underbody panel is not equipped with an oil filter access hole, you must remove, trim, and reattach it as shown in the trim diagram. The lower fascia trim must be notched to fit around the receiver tube. No drilling is required.
The kit includes: 5 carriage bolts (1/2-13 UNC, 2-1/2 inch, Grade 8), 5 serrated flange nuts (1/2-13 UNC, Grade 8), 5 square hole spacers (0.250 x 1.50 x 3.00 inch), 1 installation spacer (0.375 inch), and 1/2 inch fishwire.
No drilling is required. The hitch uses existing frame slots and holes. Installation involves fishwiring carriage bolts through the frame slots and fastening with flange nuts.
The manual does not specify required tools. However, based on the installation process, you will need a wrench or socket set to torque 1/2-inch fasteners to 110 ft.-lbs., and tools to trim the front bumper fascia and underbody panel (such as a utility knife or trim saw). A fishwire tool or similar device is needed to route the carriage bolts through the frame slots.
1. Remove the lower portion of the front bumper fascia. If the underbody panel lacks an oil filter access hole, trim it as shown in the diagram and reattach. 2. Fishwire the 1/2-inch carriage bolt and spacer into the center frame section. 3. Raise the hitch and align the mounting arm hole with the fishwired bolt. Place the circular spacer between the mounting arm and frame, then fasten with a 1/2-inch flange nut. 4. Fishwire the remaining carriage bolts and spacers through the frame slots on the inside of the frame rails. Pull bolts through the hitch side plate holes and fasten with flange nuts. 5. Torque all 1/2-inch fasteners to 110 ft.-lbs. 6. Notch the lower fascia trim to fit around the receiver tube and reposition it.
Fishwiring is a technique to route the carriage bolts through the frame slots without removing the hitch or frame. The 1/2-inch fishwire included in the kit is used to guide the carriage bolts through the slots located on the inside of the frame rails, then the bolts are pulled out through the hitch side plate holes for fastening.
The circular spacer (part CM-SP4, 0.250 x 1.50 x 3.00 inch) is placed between the mounting arm and the frame before fastening with the 1/2-inch flange nut. This ensures proper alignment and load distribution. Five spacers are included in the kit.
The side plate may be snug fitting over the sway arms during installation. You will need to rotate and push it into position carefully to ensure proper alignment before fastening.
All 1/2-inch fasteners (carriage bolts and flange nuts) must be torqued to 110 ft.-lbs.
The lower portion of the front bumper fascia must be removed during installation. After the hitch is installed, the lower fascia trim must be notched to fit around the receiver tube and repositioned on the vehicle. The trim diagram on page 1 shows the required notching.
Only if your underbody panel is not equipped with an oil filter access hole. If it lacks this hole, you must remove the panel, trim it as shown in the trim diagram, and reattach it. If your vehicle already has an oil filter access hole, no underbody panel trimming is required.
The front axle GAWR is the maximum weight your vehicle's front axle can safely support. You must not exceed this rating when using the hitch. Exceeding GAWR may overload the front axle and suspension, resulting in accident, property damage, and personal injury. Find your vehicle's GAWR in the owner's manual or on the specification plate on the driver's door frame. Measure gross front axle weight by placing the front wheels of your loaded vehicle on a scale.
Use only OEM tow hooks, recovery eyes, or a clevis mount for attachment of a tow strap or winch cable. Never use the ball mount or hitch receiver itself as an anchor point, as this can result in severe personal injury or death.
For maximum line pull rating, the winch cable must not exceed 15 degrees angle up or down from horizontal, and must not exceed 45 degrees angle left or right from straight ahead. Exceeding these angles may overload the winch, winch mount, and front mounted receiver.
Attach the return cable to the tow hook or recovery eye, not to the winch mount. Attaching the return cable to the winch mount may overload the winch mount and/or front mounted receiver.
Front-mounted accessories must not obstruct vehicle lights, grille airflow, the license plate, or the driver's view. Reposition the front license plate if obstructed. Accessories extend the front of the vehicle and may reduce approach angle, so use caution when parking and maneuvering. Rear wheel traction may be reduced, which could affect handling; reduce speed and drive with caution.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify a retorque interval, but regular inspection is essential for safe operation.
