Intro
Once you’ve determined that a weight distribution system is appropriate for your towing setup, the next step is choosing the right one.
The best hitch isn’t necessarily the most expensive or highest-rated option. It should be properly matched to your trailer, tongue weight, tow vehicle, and receiver.
1. Know Your Loaded Trailer Weight
Start with the trailer’s actual loaded weight, not just its empty weight.
Include:
- Trailer
- Cargo
- Equipment
- Tools
- Fuel
- Water
- Accessories
If you regularly change what you’re hauling, remember that your trailer weight can change from one trip to another.
2. Determine Your Tongue Weight
Tongue weight is one of the most important numbers when selecting a weight distribution system.
For many conventional trailers, approximately 10%–15% of loaded trailer weight is a commonly used starting range, but always follow your trailer manufacturer’s recommendations.
Actual tongue weight is better than an estimate, especially when you’re dealing with heavier trailers.
3. Match the Spring Bars
Choose spring bars designed for the tongue-weight range of your setup.
Avoid choosing bars simply because they have the highest available rating.
A properly matched system should provide the required weight distribution without being unnecessarily stiff.
4. Check Your Receiver Size
Make sure the weight distribution hitch matches the tow vehicle’s receiver.
Common receiver sizes include:
- 2″
- 2-1/2″
- 3″
The hitch shank and receiver need to be compatible, and the entire system must remain within the applicable ratings.
5. Consider Sway Control
If you’re towing a larger travel trailer, enclosed trailer, or other trailer that may be susceptible to sway, consider a system that includes sway control.
Integrated sway control can provide a cleaner setup than adding a separate friction-control device.
6. Check the Adjustment Range
Your hitch needs enough adjustment range to achieve the correct trailer and tow-vehicle geometry.
Look at:
- Hitch-head height
- Rise/drop adjustment
- Shank length
- Spring-bar position
- Trailer-frame bracket location
A hitch that doesn’t provide enough adjustment may not be able to achieve the setup recommended by the manufacturer.
7. Look at the Spring-Bar Design
Different weight distribution systems use different spring-bar designs.
Common configurations include:
- Round bars
- Trunnion bars
Both can work effectively when properly matched and installed.
The design can affect ground clearance, adjustment, installation, and how the system interacts with the trailer.
8. Check Trailer Compatibility
Before buying, verify that the hitch is compatible with your trailer.
Pay attention to:
- Trailer-frame dimensions
- Frame-mounted brackets
- Available clearance
- Coupler design
- Battery or propane locations
- A-frame configuration
Some trailers may require specific installation considerations.

💡 Wayman’s Tip
Take measurements before you buy. Knowing your receiver size, trailer-frame dimensions, loaded trailer weight, and tongue weight can prevent you from buying a hitch that looks right online but doesn’t actually fit your towing setup.
