While cars, trucks, and SUVs excel at transporting passengers from one place to another, they often fall short when it comes to handling the demands of a society that loves accumulating and moving large quantities of belongings.
Thankfully, trailers provide the perfect solution for transporting oversized items. Whether you're hauling dirt bikes for an off-road adventure or moving a boat from your home to the water, trailers are indispensable. However, they also raise important questions: How do you properly attach them? Is your vehicle capable of towing the load? Do you have all the necessary hitch accessories? Addressing these concerns is crucial for ensuring a safe and legal journey with your cargo in tow.
Thankfully, mastering the proper selection and use of towing equipment is straightforward. This article focuses on addressing situations where your vehicle's receiver hitch doesn't align properly with the trailer's tow apparatus. We'll also define and clarify the common terms for towing components. The key accessory you'll need to match your vehicle's towing height with the trailer is the drop hitch receiver.
Drop hitch receivers serve a single purpose: adjusting the height of the trailer hitch receiver. Typically, it's a square, steel tube attached to the rear underside of your vehicle. This accessory ensures a secure connection between your vehicle and trailer, preventing imbalance and potential loss of control.
You might have noticed vehicles with trailers causing the rear to sag, resembling an overburdened mule. This scenario is dangerous as it shifts weight away from the front wheels, compromising steering control. Proper hitch accessories, like drop hitch receivers, can mitigate this issue by leveling the trailer and distributing its weight evenly.
Drop hitch receivers are designed to fit into standard receiver hitch openings, offering vertical adjustments ranging from 2 inches to over 10 inches. This ensures a balanced connection between your vehicle and trailer. Virtually every four-wheeled vehicle has compatible towing equipment available. In the following section, we'll explore how to select the right drop hitch receiver.
Selecting the Right Drop Hitch Receivers

Before selecting any towing equipment, the primary question to ask is, "How will it affect my vehicle?" Always refer to your vehicle's owner manual for towing capacity and recommendations. Exceeding your vehicle's towing limits can strain the engine and brakes, significantly raising the risk of accidents. Safety should always be your top priority when towing.
Many new car and truck manufacturers provide a "towing package" that includes enhanced brakes, a more robust engine cooling system, and all the essential towing hardware.
In the United States, tow hitch receivers are classified based on their towing capacity, which is determined by weight categories:
- Class 1 - 1,000 to 2,500 pounds gross trailer weight (total weight of the trailer and its contents)
- Class 2 - 3,500 GTW
- Class 2.5 - 4,000 GTW
- Class 3 - 6,000 GTW
- Class 4 - 8,000 GTW Class 5 - 10,000 GTW
Once you've installed the correct class of trailer hitch on your vehicle, the next step is to measure the height difference between the hitch and the trailer's connecting point.
The trailer hitch assembly is made up of several straightforward components. At its core is the trailer hitch receiver, a sturdy steel frame welded into a shape that bolts securely to the vehicle's underside. It features a square opening (ranging from 1 ¼" to 2 1/2" depending on the class) designed to hold the drop hitch. The drop hitch, constructed from rectangular welded steel, extends the standard trailer hitch's reach. It slots into the vehicle's original hitch and is secured with a locking pin. The ball mount connects a short square steel tube to a steel flange, which has a hole for the hitch ball. The ball mount attaches to the trailer hitch receiver using a locking pin, and the hitch ball is fastened with a threaded shaft and nut. Ensure the hitch ball's diameter matches the trailer's coupler. If you're unsure about the right specifications, consult a trusted dealer or towing specialist.
While modern vehicles rely heavily on advanced electronics, towing accessories remain a domain where DIY enthusiasts can still work without needing technical expertise. To discover how to install a drop hitch receiver, proceed to the next page.
Unsure about the required drop or rise for your hitch receiver? Here's an easy method to find out. Start by measuring the distance from the ground to the top inside edge of your vehicle's square receiver tube. Next, measure from the ground to the bottom of your trailer's coupler. The difference in inches between these two measurements will tell you the necessary drop or rise for your drop hitch receiver [Source: etrailer.com]. Alternatively, consider an adjustable drop hitch receiver, which offers multiple height options in a single unit.
How to Install Drop Hitch Receivers

Most manufacturers of drop hitch receivers and towing gear aim to create products that are easy to install. These items are typically designed for straightforward attachment using basic tools, without the need for complex wiring or significant alterations to your vehicle. If welding is necessary, the product is no longer considered a simple bolt-on solution.
Seasoned DIY enthusiasts understand that "bolt-on" installations often involve some light adjustments, such as filing, sawing, or minor modifications, to ensure a perfect fit. Installing drop hitch receivers and similar towing equipment can significantly impact your vehicle's safety and performance. Always adhere to the specified torque settings for fasteners and use locking washers as recommended. If you're inexperienced or unsure, it's best to consult a professional for assistance.
The installation process for a drop hitch receiver is relatively simple. In fact, it's even easier than a typical "bolt-on" setup: You just need to insert it into the vehicle's standard receiver hitch and secure it with a locking pin. [Source: Blue Ox]
You can also invest in various hitch accessories that improve safety and load control, such as weight distribution hitches, sway control devices, and stabilizers. While these may require more effort to install, they help alleviate concerns when towing a trailer. Challenges like wind gusts, passing trucks, and unpredictable drivers make towing more demanding than regular driving. Slowing down, stopping, and turning require extra caution and planning. These accessories are designed to restore stability and control, ensuring that towing a boat, RV, ATVs, or horses remains an enjoyable experience.
