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 Toyota Crown Signia (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW.
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.

Depending on the vehicle application, available options may include Class 3, Class 4 and heavy-duty receiver hitches with different gross trailer weight and tongue weight capacities.
A 2" x 2" receiver opening is one of the most common hitch sizes and works with a wide range of towing accessories, including ball mounts, bike racks, cargo carriers, hitch steps and tow hooks. When towing a trailer, you may also need a properly rated trailer ball, hitch pin, wiring harness, brake controller or weight distribution system.
CURT trailer hitches feature a durable black finish designed to help protect against rust, scratches and exposure to road conditions. Many models install using existing holes in the vehicle frame, although drilling, trimming or temporary removal of vehicle components may be required for certain applications.
Use our vehicle fitment tools to find the correct CURT 2" trailer hitch for your year, make and model. Always compare the hitch rating with your vehicle’s towing capacity and the ratings of every component in your towing setup. The maximum towing capacity is determined by the lowest-rated component.
