Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Chevy Silverado 1500, 1500 Classic, 1500 HD, 1500 HD Classic or 2500 HD and GMC Sierra 1500, 1500 Classic, 1500 HD, 1500 HD Classic or 2500 HD (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 8,000 lbs. GTW and 800 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 12,000 lbs. WD and 1,200 lbs. WDTW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.

No. The Curt 13339 requires no drilling. It uses existing M14 bolts and weldnuts on the vehicle frame rails. If these do not exist on your vehicle, the supplied 1/2-13 hex bolts and CM-SP22 spacers can be used in the rear hole instead.
The hitch includes: 6 hex nuts (1/2-13 UNC, Grade 8, part 20-00171), 6 hex cap screws (1/2-13 UNC, 1-3/4", Grade 8, part 10-10370), 6 lock washers (1/2", part 30-00153), 6 round hole spacers (0.250 x 1.00 x 1.50", part CM-SP50), 2 round hole spacers (0.188 x 1.50 x 3.00", part CM-SP34), and 4 round hole spacers (0.250 x 1.50 x 1.50", part CM-SP22).

1. Lower the spare tire. 2. Remove M14 bolts from the bumper bracket. 3. Raise the hitch into position and reinstall the M14 bolt. 4. Install 1/2-13 hex bolts and CM-SP22 spacers through the middle holes (or rear holes if M14 bolt and weldnut do not exist). 5. Install 1/2-13 hex bolts and CM-SP34 spacers through the forward holes. 6. Secure the hitch with CM-SP50 spacers, lock washers, and hex nuts. 7. Torque all 1/2" hardware to 110 lb-ft. 8. Reinstall the spare tire.
All 1/2" hardware (hex bolts, lock washers, and hex nuts) must be torqued to 110 lb-ft. Use a torque wrench to ensure proper tightness.
CM-SP22 spacers (0.250 x 1.50 x 1.50") go through the middle holes with 1/2-13 hex bolts. CM-SP34 spacers (0.188 x 1.50 x 3.00") go through the forward holes with 1/2-13 hex bolts. CM-SP50 spacers (0.250 x 1.00 x 1.50") are used with lock washers and hex nuts to secure the hitch. If the M14 bolt and weldnut do not exist on your vehicle, use CM-SP22 spacers in the rear hole as well.
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, so contact Curt Manufacturing technical support at 1-877-287-8634 for maintenance recommendations.
