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 2500 HD or 2500 HD Classic and GMC Sierra 2500 HD or 2500 HD Classic (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 6,000 lbs. GTW and 600 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 10,000 lbs. WD and 1,000 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.
Trailer hitch weight ratings are limited to vehicle manufacturer's stated capacities
Not compatible for use with vertical hanging bicycles (bike racks that require the bicycles to be hung / mounted vertically)

No. The manual states "NO DRILLING REQUIRED" for this hitch. Installation uses existing frame attachment points and does not require any drilling, cutting, or permanent modifications to the vehicle frame.
The manual does not specify which tools are required for installation. You will need a socket or wrench to remove the existing 14mm hex bolts from the frame ends and to install the new fasteners.

1. Remove the 14mm hex bolt from each end of the frame. 2. Remove and relocate the ground wire and ground wire bolt on the driver's side frame rail. 3.
