Tow Ball

A tow ball is an attachment that provides a connection between the trailer and the hitch.

Pairing a car or motorcycle trailer with a tow hitch allows you to move your vehicle along with your belongings in one single trip. You can also use these pieces of equipment to tow an out-of-service vehicle to a repair shop or transport a vehicle to a new location when you only have a single driver.

To satisfy the growing demand in the market, we commenced manufacturing of many ball sizes. Our largest truck ball size is 3″ for our 10 ton gooseneck coupling.

To ensure compliance with regulations, we use UKAS/SGS ISO9001 testing facilities & procedures to test our towing equipment in-house before shipping them to our customers.

U-Bolt Kit

U-bolts are mainly used for the connection between the trailer axle and bumper springs. U-bolts are a much easier way to clamp any kind of tubing/round bar.
Our U bolt kit includes U-bolts, plates, nuts, and washers, which can be easily assembled onto the trailer axle and the bumper spring.

Galvanized plated hardware resists rust and corrosion and is superior for boat trailers and weather resistance purposes. Furthermore, we use mechanical galvanizing which means it does not cause hydrogen embrittlement hazard to high-strength steel parts; it's stronger, tougher, and safer.

Dust Cover

Dust covers and wheel bearing protectors help to keep dust and dirt out of the wheel, to ensure that the trailer wheel axis is clean & lubricated, to promote smooth, safe towing of your trailer. The wheel bearing protector automatically maintains internal pressure to avoid seal damage and continuously lubricates the axle center to avoid jamming.

Your trailer’s wheel axle needs to be lubricated to dissipate heat, stave off corrosion, and keep those wheels a-rolling. There are a few general types of wheel-bearing lubrication systems, each with its particular maintenance characteristics.

Coupling

Coupling is primarily used on the trailer to perform the enormous task of pulling a variety of heavy loads at highway speeds.

Trailer couplings come in standard sizes, and many can be adjusted for a more secure connection. Our range of trailer couplings is engineered to meet the highest specifications to ensure reliable attachment for trailers of varying weights and load sizes.

Pintle Hook

A pintle hitch is a tow hitch that uses a tow ring or coupling configuration to secure a hook or a ball combination to tow an unpowered vehicle.
Pintle hooks give you a reliable connection for your heavy-duty trailer.

Our pintle hook kits include ball mount style hitches and jawed pintle mounts which offer excellent flexibility of movement. Furthermore, we provide options for a combination of receiver bar, pintle hook, and a tow ball, for towing multiple types of trailers, providing further versatility.

Receiver Adaptor

Using our tow bar adaptor eliminates the need to buy a base plate or a tow bar.
The pintle hook adaptor can be used to convert your tow bar configuration, from a ring coupling trailer to a pintle hitch heavy-duty receiver-style towbar.

Receiver Bar

The receiver mount can take the form of a tow ball to allow swiveling and articulation of a trailer, or a tow pin, or a tow hook with a trailer loop. It is one of the most common methods to mount a pintle hook.

The receiver bar is designed according to the height between the vehicle tail and the trailer front. The receiver bar end is connected to the trailer hitches, which will set the tow ball locked on the other end of the receiver bar. This is a standard trailer setup.

Whether you’re taking your new boat to the lake for a summertime spin or towing your camper into the mountains, you’ll need a tow hitch (also called a trailer hitch) attached to your vehicle.

Safety Chain Holder

The safety chain anchor plate is a safety device connected from the trailer equipment to the trailer.

The safety chain anchor plate is an indispensable part to ensure that the trailer is properly connected to the trailer.
To ensure that in the event of a tow ball or coupling failure, you can still safely guide the trailer and maintain control, so that you can stop the vehicle stably and avoid dangerous situations.

Two safety chains are required and must be connected to their own chain holder. The safety chain anchor plate is just one small detail. If used incorrectly, it may cause major problems. Of course, the safety chain anchor plate increases the safety and responsibility of driving.

Ensuring that the function of the safety chain anchor plate is effective and connected is the first step of road safety.

Axle Drop Plate

Axle drop plates are normally applied to satisfy the need for low access of trailers.
Our Axle Drop Plates are manufactured to suit 3” and 4” Axle Drops.

Receiver Pin and Lock

Securing your trailers is important! We supply a wide selection of locking solutions to keep your trailers safe and secure.

Security of trailers is of upmost importance.

We provide a variety of locking solutions to satisfy all customer and trailer requirements to keep your trailer safe.

Axle Electric Weld Ring

Our Axle Weld Rings are available in two major types: square-shaped and round-shaped. The square-shaped weld ring features a round hole at the center and four-bolt holes near each corner.

Our round-shaped weld rings have two options: square center hole and round center hole. Both are surrounded by five smaller holes near the edge.
