Trailer Ball

The king of the haul, the trailer ball sits at the rear of your towing vehicle, waiting to connect to your trailer’s coupler. The right size and weight capacity are vital for a safe and secure connection.


This sturdy contraption on your trailer’s tongue latches onto the ball, creating a solid union between your truck and trailer. There are different coupler types, so ensure your coupler matches your ball and towing needs.


The unsung hero, the trailer hitch, connects the coupler to the frame of your tow vehicle. Ensure it’s rated for the weight you’ll be hauling and adequately installed for maximum safety.


A trusty trailer jack is your best friend when hitching, unhitching, and leveling your trailer. You need a jack with the appropriate weight capacity and crank mechanism for safety and effortless operation.

Trailer Wheels and Tires

Always check the tread pattern before rolling for any signs of damage or uneven wear. Replace worn tires with a suitable weight capacity and tread pattern for your expected load and road conditions. Remember that some states like California, Colorado, Georgia, Idaho, Nevada, and Washington require snow tires or chains as a matter of law when hauling during the winter.


Breakaway Switch

This safety device activates the trailer’s brakes if it separates from the hitched vehicle, preventing a runaway trailer.

Trailer Axles

The sturdy muscles of your trailer axles rotate the wheels to support the weight of your load. They are mounted to the trailer with bearings. There are different axle types for various weight capacities and configurations.

Drums and Brakes

Like on your car or truck, trailer drums house the braking system that stops your trailer when you use the brake. Regularly inspect your brakes for wear before hitting the road and replace them when necessary.

Florida, Washington, and other states require drivers to secure their load to avoid objects and debris from falling out of the trailer while on the highway.
