What is a bolt on hitch?
A bolt-on hitch is a trailer hitch that attaches to a vehicle's frame using bolts rather than welding, making it easier to install, remove, or transfer between vehicles.
How bolt-on hitches work
Bolt-on hitch systems use a receiver mounted to the vehicle frame and secured with bolts. A crossmember or mounting brackets are fastened to the frame, and the hitch receiver slides into or bolts to these brackets. A towing accessory such as a ball mount attaches to the receiver, and a wiring harness powers trailer lights. The setup emphasizes modularity and reversibility, letting drivers upgrade or remove the hitch as needed.
Key components
Hitch kits typically include the essential parts needed for installation and towing. The following list outlines common elements you should expect in a bolt-on hitch kit.
- Receiver tube (commonly 1-1/4" or 2" openings)
- Mounting brackets and frame adapters
- Bolts, nuts, and washers (often Grade 8 or stainless)
- Hitch crossmember or reinforcement plates
- Hitch ball mount and towing accessories
- Safety chain anchors and hooks
- Electrical wiring harness for trailer lights
- Installation instructions and corrosion protection (coatings, sealants)
Having these parts ensures a complete, functional bolt-on hitch setup and helps buyers assess whether a kit is ready for their vehicle.
Types, compatibility, and ratings
Bolt-on hitches come in different receiver sizes, classes, and mounting configurations to fit a wide range of vehicles—from cars to full-size trucks. They are largely defined by the receiver opening, class rating (I to V), and whether the installation is truly bolt-on or requires some frame modification.
Receiver sizes and class ratings
The most common receiver sizes are 1-1/4" and 2". Class I and II hitches are lighter-duty, while Class III, IV, and V offer higher tongue weight and gross trailer weight capacities. Some vehicles use OEM bolt-on kits designed specifically for that model.
Vehicle compatibility considerations
Before purchasing, confirm that the hitch aligns with your vehicle’s frame structure, exhaust routing, and bumper design. Some modern vehicles require specialized mounting brackets, drilling, or frame modifications, while others have factory mounting holes that simplify installation. Always consult the hitch manufacturer’s fit guide and, if in doubt, seek professional installation.
There is also a distinction between bolt-on and weld-on: bolt-on hitches attach with bolts to the frame or reinforced brackets, while weld-on versions require welding to the frame and are not easily removed. Bolting-on is advantageous for temporary use, transfer between vehicles, or non-permanent setups.
Installation considerations and safety
Installation difficulty and the need for professional service vary by vehicle and hitch. Many bolt-on hitches are designed for DIY installation, but some vehicles, high towing demands, or complex exhaust routing may warrant professional installation to ensure safety and proper alignment.
Below is a typical sequence of steps for installing a bolt-on hitch, presented as a general guide. Individual vehicles and kits may differ, so always follow the manufacturer's instructions.
- Check vehicle compatibility using the hitch’s fit guide and your vehicle’s year, make, and model.
- Prepare the vehicle: lift safely and access the frame; remove obstructions as needed.
- Align the mounting brackets with factory or reinforced holes in the vehicle frame, then hand-tighten bolts to hold components in place.
- Torque bolts to the manufacturer’s specifications using the proper tools and, if recommended, apply thread-locking compounds or anti-corrosion coatings.
- Install the hitch receiver and crossmember, then attach the hitch ball mount and any additional towing accessories.
- Connect the trailer wiring harness and test the trailer lights to ensure proper operation before towing.
After installation, regularly inspect the bolts for tightness and signs of rust or stress, especially after towing heavy loads or exposure to road salt.
Cost and maintenance considerations
Bolt-on hitches vary in price based on capacity, brand, and vehicle compatibility. Maintenance involves periodic cleaning, protection against corrosion, and re-torquing bolts after the initial break-in period or after heavy towing.
Summary
Bolt-on hitches are modular, frame-mounted trailer hitches secured with bolts rather than welding. They offer easier installation, transferability between vehicles, and a pathway to higher towing capacities, but success depends on correct fit, proper installation, and ongoing maintenance for safe towing.
Is it illegal to drive around with a trailer hitch on?
Safety Considerations: While it's legal to drive with a hitch, it's generally a good idea to remove the towball when not towing, especially for insurance reasons and to avoid potential damage to other vehicles. It's not your fault if a person drives into the rear of your car, that's their fault.
What are the two types of hitches?
The three basic types of trailer hitches are receiver hitches, 5th wheel hitches, and gooseneck hitches. Receiver hitches are the most common and broken up into five different classes based on maximum weight. 5th wheel hitches and gooseneck hitches are heavy-duty hitches that attach into the bed of trucks.
Are tow hitches bolted or welded?
Bolt-on hitches offer easy installation and removability, making them ideal for leased or multi-use trucks. Weld-on hitches deliver greater strength and long-term reliability, making them best for dedicated heavy-duty towing.
Can you put a hitch on a bolt?
Adding a trailer hitch to a Chevy Bolt requires only a few tools, a ECOX7359 trailer hitch, and a short amount of time to complete the installation.
