Yes, the Curt 12011 is designed for 1983–2004 Chevrolet and GMC S-10, S-15, and Sonoma pickups. The manual includes specific installation instructions for step bumper models, which apply to your 1999 Sonoma.
Yes, the Curt 12011 is compatible with 1996–2000 Isuzu Hombre pickups.
The Curt 12011 has a gross load capacity of 3500 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, which may be lower.
The Curt 12011 is designed for use with ball mount part number D-19 / 45519.
The kit includes: 6 M12×1.75 hex head cap screws (HHCS) class 10.9, 12 flat washers (1/2"), 6 lock washers (1/2"), and 6 hex nuts (M12×1.75 class 10). These fasteners are used to attach the hitch to the frame and bumper brackets.
No, drilling is not required. The Curt 12011 is designed to use existing frame and bracket holes.
Yes, for step bumper models you must remove the bumper, though the brackets remain attached to the frame. For bumper bracket configuration models (1994–1997), you remove the bumper bracket bolts. The installation process differs slightly depending on your model year and bumper type.
The manual notes that some spare tires may need to be lowered and repositioned for hitch installation. If your vehicle uses an early model cradle storage system for the spare tire, you may need to cut off part of the carrier along the frame edge. Consult the manual's Step Bumper Models section for details on this modification.
The manual does not specify required tools. However, installation involves removing and reinstalling bumpers and brackets, disconnecting bumper wiring, and tightening M12 fasteners to 79 lb.-ft, so you will need standard wrenches, sockets, and a torque wrench. Consult a professional installer if you are unsure about bumper removal or wiring work.
1. Remove the bumper, leaving brackets attached to the frame. Disconnect bumper wiring and remove wiring guides from the brackets. 2. Remove bumper brackets from the frame. 3. If using a cradle spare tire storage system, mark and cut the carrier 1/8" inboard of the outer frame edge, then lower the spare tire. 4. Position the receiver on the frame and loosely install bumper brackets using 3 M12 bolts and fasteners per side. 5. Reinstall the bumper on the bumper brackets with original bolts and 1/2" washers as spacers (pre-1994 models only). 6. Raise the spare tire and secure it. Reconnect bumper wiring. 7. Torque all fasteners to 79 lb.-ft.
1. Remove bumper bracket bolts and return them to the vehicle owner. 2. Position the hitch on the frame and install fasteners as shown in the diagram.
Three M12 bolts and fasteners are used per side (6 total) to attach the receiver brackets between the bumper brackets and frame.
Yes, if you have a pre-1994 model, use three 1/2" flat washers at each bolt location as spacers between the bumper brackets and bumper when reinstalling the bumper.
All fasteners must be torqued to 79 lb.-ft.
The fasteners are M12×1.75 hex head cap screws (class 10.9) with matching M12×1.75 hex nuts (class 10). Flat washers (1/2") and lock washers (1/2") are also used.
Install fasteners loosely first. Step 4 of the Step Bumper Models instructions states to "loosely install" the bumper brackets. Only after the bumper is reinstalled and the spare tire is raised should you torque all fasteners to 79 lb.-ft in step 7.
The hitch has a gross load capacity of 3500 lbs trailer weight and 350 lbs tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating. Always follow your vehicle's towing limits.
Periodically check that all fasteners are tight and that all structural components are sound. This helps ensure safe operation and extends the life of the hitch.
Yes, if your vehicle uses an early model cradle storage system for the spare tire, you must mark the spare tire carrier 1/8" inboard of the outer frame edge and cut off the carrier along that line to allow hitch installation. After cutting, lower the spare tire, install the hitch, then raise and secure the spare tire.
Yes, cutting the spare tire carrier is a permanent modification. The manual instructs you to cut off the carrier along a marked line 1/8" inboard of the outer frame edge. This modification cannot be reversed.
The Curt 12011 fits 1983–2004 Chevrolet and GMC S-10, S-15, and Sonoma pickups (including Sport Side), and 1996–2000 Isuzu Hombre.
