Yes, the Curt 13017 is designed for 1973–1991 Chevrolet and GMC Suburban models. However, installation requirements vary by model year. Earlier models in this range require drilling of frame holes, while later models may use existing frame holes. Consult the installation steps to determine whether your specific year requires drilling.
No. The Curt 13017 is engineered specifically for 1973–1991 Chevrolet and GMC Suburban models only. Do not use on other model years or vehicle types.
The Curt 13017 has a gross load capacity of 10,000 lbs. trailer weight and 1,000 lbs. tongue weight when used as a weight distribution hitch. When used as a weight carrying hitch, the capacity is 6,000 lbs. trailer weight and 600 lbs. tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
The kit includes 4 square hole spacers (CM-SP1, 0.250 × 1.50 × 2.00 inches), 4 Grade 8 serrated flange nuts (1/2–13 UNC, part 20-00062), and 4 Grade 8 carriage bolts (1/2–13 UNC, 1-3/4 inches long, part 10-10272). All fasteners are Grade 8 and zinc-plated.
Yes. The manual notes that the wiring harness may be located within the vehicle's frame. You must reposition the harness prior to drilling any holes necessary for installation. This prevents damage to electrical components during the drilling process.
No. Drilling is required only on earlier models within the 1973–1991 range. Later models in this range use existing frame holes. The manual does not specify the exact year cutoff. Position the receiver to line up with existing holes in the frame; if holes do not align, drilling will be necessary.
1. Position the receiver to line up with all existing holes in the frame. It may be necessary to deflect side brackets slightly to align all existing holes, particularly near the fuel tank. 2. Install all fasteners (bolts, spacers, and nuts) as shown in the diagram. 3. Torque all fasteners to 110 lb.-ft.
It may be necessary to deflect the side brackets slightly to line up all existing holes in the frame, particularly near the fuel tank. This is not always required; attempt to position the receiver first. If holes do not align, slight deflection of the brackets may be needed.
All fasteners must be torqued to 110 lb.-ft.
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 check interval; perform this inspection regularly, especially before towing.
No. Do not exceed the hitch's gross load capacity (10,000 lbs. trailer weight / 1,000 lbs. tongue weight for weight distribution use, or 6,000 lbs. / 600 lbs. for weight carrying use). Additionally, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating.
