Out of the monotony comes one name that rises above all others. CURT trailer balls are designed for strength, ease of use and, ultimately, to get you to your destination without hassle. CURT 2" trailer hitch balls are constructed from quality steel and are made with precision to fit your 2" trailer coupler like a hand in a glove. They are able to tow most standard-duty and heavy-duty trailers such as utility trailers, boat trailers, campers, livestock trailers and recreational vehicle trailers for hauling ATVs, snowmobiles, personal watercraft and more. These tow balls are an excellent extension of your class 3 or class 4 trailer hitch and ball mount, and are the ideal choice for most pickup trucks and SUVs (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc).This particular 2" trailer ball offers a ball capacity of 6,000 lbs. It features a 1" shank diameter, a 2-1/8" shank length, 1" of rise and a nickel-chrome finish to protect against rust and scratches. With its fine-threaded shank, this 2" trailer ball also offers an added measure of holding strength and provides smooth installation and torqueing. To give you peace of mind while towing to that next destination, we also carefully test our trailer balls and ensure that each one meets U.S. VESC specifications.
CURT offers custom trailer hitches, electrical products and a complete line of towing accessories to get you there with confidence and enjoy every mile of the journey.
A trailer hitch ball may be one of the simplest components of your hitch system, but it is also the direct connection between your vehicle and trailer, making it vitally important.
CURT trailer balls are available in a wide variety sizes and capacities. Whether youâre towing a full-size travel trailer or a simple utility trailer, you can rest assured in the reliability of your CURT towing connection.
CURT stainless steel tow hitch balls are a premium option, offering superior rust resistance. They are available in various ball diameters and GTW capacities, and each one features fine threads for improved holding strength.
CURT chrome trailer hitch balls are available in multiple diameters and GTW capacities, and like our stainless steel balls, they also feature fine threads. Their chrome finish over steel gives them solid resistance to rust and wear.
CURT hitch balls with a raw steel finish are intended for heavy-duty towing applications. They range in GTW capacity from 12,000 pounds to 30,000 pounds and feature a heat-treated construction for added wear resistance.
There are four key factors that must be considered when selecting a trailer hitch ball for your towing setup.
1. Weight rating.
2. Coupler size.
3. Hole size.
4. Platform thickness.
To learn more about each of these factors, see the panel below. The diagram to the right shows the various measurements of a trailer ball, which may be referred to in the following sections.
Before selecting a trailer hitch ball, it is important to know how much weight youâll be towing. Each trailer balls is rated to certain gross trailer weight capacity and tongue weight capacity. The gross trailer weight is the total weight of the trailer, while the tongue weight is the weight specifically at the coupling point.
Remember, your towing capacity is always limited by the lowest-rated towing component, whether thatâs the vehicle, the trailer hitch or the tow ball.
The second important factor to consider is the size of your trailer coupler. Many couplers are adjustable, but only within a limited range.
When selecting a tow hitch ball, choose one with a ball diameter that matches the coupler size. It is extremely dangerous to attempt to tow without a matching tow ball and coupler.
'Hole size' refers to the diameter of the mounting hole into which the trailer hitch ball shank is inserted. The diameter of the hole must be no more than 1/16â larger than the diameter of the shank.
If you already own a ball mount or bumper with a mounting hole that is too larger, you may be able to make up the difference using a CURT reducer bushing of the appropriate size.
The thickness of the mounting structure is also vitally important, whether that mounting structure is a CURT ball mount, fixed-tongue trailer hitch or a bumper. The platform must be at least 3/8â thick to be considered safe for towing.
If the mounting platform is too thick, CURT trailer balls are available with a variety of shank lengths, including up to 3-1/2".
