How to Choose the Correct Axle-Less Trailer Suspension for Your Off-Road Trailer
New Timbren video: How to choose the correct Axle-Less suspension for your trailer
You’re building a trailer and considering which suspension to go with. You’ve got your eye on the Axle-Less system, but not sure which one is the best for you.
So, where do you begin?
Whether you’re building your own trailer or retrofitting an existing one, the process of choosing the correct axle-less suspension is the same.
First, determine the combined weight of your trailer and its cargo. Your local truck scale can give you an accurate reading.
When building a trailer, you’ll need to tally the weight of each piece. A chart of metal weight ratings will help. Don’t forget to add the weight of each piece of cargo and accessory you plan on using.
A simple formula
With the weight determined, a simple formula helps identify which axle-less suspension is right for your rig. Take the total weight of your trailer and add another 20%. If your loaded trailer weighs 2,600 pounds, an additional 20% equals 3,120 pounds. The next size up on the axle-less chart is rated at 3,500 lbs.
Standard or HD?
You’re also going to need to determine if you’re going to need to standard suspension or the HD version. If you’re going to stick to the pavement, you should choose the standard suspension.
However, if you plan to go off-road or do any overlanding whatsoever, we recommend you choose the HD version that has heavier gauge steel and a more robust design.
Choose your spindle
Okay, now it’s time to figure out which outboard-arm and spindle configuration to use.
Tire size determines which spindle arm to use. A regular-sized trailer tire measures up to 235 millimeters (9.25 inches) in width. Anything wider is considered a wide tire and will require a longer spindle arm.
Don’t forget the ride height
Finally, you’re ready to select a ride height.
Along with the standard height, there are options for ‘lifting’ and ‘lowering’ your trailer’s ride height. A 4” drop spindle is available to lower it. And a 2” or 4” lift will raise it.
