The manual specifies a gross load capacity of 3,500 lbs. trailer weight and 350 lbs. tongue weight when used as a weight-carrying hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity.
The kit includes: 2× 1/2-13 UNC carriage bolts (2-1/4"), 2× 1/2" flat washers, 2× 1/2" lock washers, 3× 3/8-16 UNC hex cap screws (1-1/4"), 6× 3/8" flat washers, 2× 0.250 × 1.50 × 2.00" square hole spacers, 2× 1/2-13 UNC hex nuts, 3× 3/8-16 UNC nylon lock nuts, and 1× 1/2" fishwire.
You will need a 3/8" drill bit to enlarge the E/A bolt holes. A torque wrench is required to properly tighten the fasteners to specification (1/2" fasteners to 110 lb.-ft. and 3/8" fasteners to 45 lb.-ft.). Standard wrenches or sockets will be needed to install and tighten the bolts and nuts.
On most vehicles, the bumper does not need to be removed. However, on El Camino and Caballero models, the bumper must be removed along with the E/A assembly to allow the carriage bolts to be fishwired from the rear frame opening.
Yes. Step 2 of the installation requires you to enlarge the E/A bolt holes using a 3/8" drill bit. This is a permanent modification to the vehicle's existing attachment points.

The 3/8" hex cap screws and nylon lock nuts must be torqued to 45 lb.-ft.

While the Curt 12005 has a gross load capacity of 3,500 lbs. trailer weight and 350 lbs. tongue weight, you must not exceed your vehicle manufacturer's recommended towing capacity. Always follow your vehicle's specifications.
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 particular interval, so regular visual inspection before each use is recommended.
