Curt part number 14108 is designed for 2007 Chevy and GMC HD Pickups with a 6-foot bed. If your vehicle matches this year, make, model, and bed length, this hitch is compatible. Do not use on other bed lengths or model years without confirming fitment with the manufacturer.
The manual specifies two capacity ratings depending on hitch type: when used as a weight-carrying hitch, the gross load capacity is 10,000 lbs trailer weight and 1,000 lbs tongue weight; when used as a weight-distribution hitch, it is 12,000 lbs trailer weight and 1,200 lbs tongue weight. You must not exceed your vehicle manufacturer's recommended towing capacity, whichever is lower.
The kit includes: 4× square hole spacers (CM-SP1, 0.250 × 1.50 × 2.00 inches), 4× 1/2-13 UNC Grade 8 carriage bolts (1-3/4 inches), 4× 1/2-13 UNC Grade 8 serrated flange nuts, 4× M14×2 Class 10.9 hex cap screws (40mm), 2× 9/16-inch standard washers, 2× 9/16-inch lock washers, and 2× 9/16-inch flat washers.
No. The manual explicitly states "NO DRILLING REQUIRED" for this hitch. Installation uses existing frame holes and weldnuts.
1. Remove the 14mm hex bolt from each end of the frame. 2. Remove and relocate the ground wire and ground bolt on the driver's side frame rail. 3. Raise the hitch into position and install the fasteners as shown in the diagram. 4. Torque all 1/2-inch fasteners to 110 lb-ft and all 14mm fasteners to 126 lb-ft.
All 1/2-inch fasteners must be torqued to 110 lb-ft.
All 14mm fasteners must be torqued to 126 lb-ft.
The manual does not mention battery disconnection. This installation involves mechanical fastening only and does not involve electrical work.
The manual does not specify which tools are required. You will need a socket or wrench set to fit 1/2-inch and 14mm fasteners, and a torque wrench capable of measuring up to 126 lb-ft. Contact the manufacturer or your installer if you need a complete tool list.
After installation, periodically check that all fasteners are tight and that all structural components are sound. The manual recommends regular inspection to ensure the hitch remains secure during use.
Do not exceed your vehicle manufacturer's recommended towing capacity. The Curt 14108 has a maximum capacity of 10,000 lbs trailer weight (weight-carrying mode) or 12,000 lbs (weight-distribution mode), but your vehicle's limit may be lower. Always follow the vehicle manufacturer's specification.
