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 Hummer H3 (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 5,000 lbs. GTW and 500 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 5,500 lbs. WD and 550 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.

CURT – Replacement OE 4-Way Flat Socket (T s into USCAR) (Part No.55384)

Replacement OE 4-Way Flat Socket (T s into USCAR)

from

$33.49
Stress is the last thing you should feel when towing a trailer — whether you’re hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it. CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Though this special socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle’s wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular connector provides a 4-way flat socket while retaining use of the existing OEM socket. It is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle). It comes with a dust cover to keep the connector socket clean when not in use.

Product Features:
  • Plugs into USCAR connection to add 4-way flat and retain use of existing socket
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • 4-way flat output connects tail lights, brake lights and turn signals
  • Dust cover included to keep connector clean when not in use
  • Slit loom keeps wires contained and well protected

Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer’s electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road.

This 7-way OEM USCAR replacement connector is designed to plug into a twist-in OEM vehicle socket and supply power for tail lights, turn signals, electric trailer brakes, a 12-volt battery, reverse lights and brake lights, as well as a ground connection. It features rust-free black plastic construction and comes with a spring-loaded cover to keep out dust and water. This 7-way RV blade connector is a female-end socket, specifically designed for the vehicle side of the connection (see application info to verify fitment with your vehicle).
