The 82 - 90 GMC S15 2in. CURT Trailer Hitch + Ball Mount + Cover + Lock Kit HWA1137 (Part #HWA1137) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Curt 13132 receiver hitch fits 1983–2004 Chevrolet S-10 Pickup, GMC Sonoma Pickup, and GMC S-15 Pickup with Sportside bed models, and 1996–2000 Isuzu Hombre. Confirm your vehicle year, make, model, and bed style before purchase.
The manual notes that some spare tires may need to be lowered or repositioned slightly for hitch installation. For step bumper models with a cradle storage system, the spare tire carrier must be cut along a marked line 1/8" inboard of the frame's outboard edge, then the spare tire is raised back to position after installation.
No. The manual explicitly states "NO DRILLING REQUIRED."
Yes. For Sportside bed models, you must remove the bumper, leaving brackets attached to the frame, and disconnect bumper wiring before removal. For 1998-present models, also remove the plastic step thread from the top of the bumper. The bumper is then reinstalled after the hitch is positioned.
All 1/2" fasteners must be torqued to 110 lb-ft.
The manual specifies gross load capacity when used as a weight-carrying hitch and when used as a weight-distribution hitch, but the specific capacity values are blank in the provided manual. Contact Curt Manufacturing or your retailer for the exact capacity ratings. Do not exceed your vehicle manufacturer's recommended towing capacity.
The kit includes: 6× 1/2-13 UNC Grade 8 hex head cap screws, 2" length (part 10-10286); 2× 1/2-13 UNC Grade 8 hex head cap screws, 1-3/4" length (part 10-10370); 2× 1/2-13 UNC Grade 8 serrated flange nuts (part 20-00062); 6× 1/2-13 UNC Grade 8 hex nuts (part 20-00171); 10× 1/2" flat washers (part 30-00133); and 6× 1/2" lock washers (part 30-00153).
Yes. The hitch has separate attachment holes for short-bed and long-bed models. Position the hitch using the appropriate hole for your bed length.
Yes. The manual states: "Disconnect bumper wiring before removing bumper." For 1998-present models, also remove the plastic step thread from the top of the bumper before removal.
For 1998-present models, the bumper is attached to each bumper bracket by 4 vertical bolts.
Pre-1994 models require 2× 1/2" washers at each bolt location as spacers between the bumper brackets and bumper when reinstalling the bumper. 1994-present models reinstall the bumper without spacer washers. Both use original bumper bolts, and slots in the bumper bracket allow for adjustment.
Only if your vehicle uses a cradle storage system for the spare tire. Steps 3 and 4 are required for early model vehicles with this system: mark the spare tire carrier 1/8" inboard of the outboard edge of the frame, then lower the spare tire and cut off the carrier along the marked line. After hitch installation, raise the spare tire back to position and secure it.
3× 1/2" bolts per side are used to loosely reinstall the bumper brackets. The receiver brackets are sandwiched between the bumper brackets and frame.
Fasteners should be installed loosely during the initial positioning of the receiver and bumper brackets (step 5). All 1/2" fasteners are tightened to 110 lb-ft only after the bumper is reinstalled and the spare tire is raised back to position (step 8).
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.
Curt Manufacturing warrants the product to be free of defects in material and/or workmanship at the time of retail purchase by the original purchaser. If defective, Curt may repair or replace the product at their option when returned prepaid with proof of purchase. Alteration, misuse, or improper installation voids the warranty.

The manual provides detailed instructions only for Sportside bed models with step bumper configurations. For vehicles with regular bumpers, refer to the installation notes or contact Curt Manufacturing, as the manual does not cover this configuration.
