Under our strong and lightweight Expedition Trailer chassis hangs the part that lets the whole rig get down the road. The Suspension  – The axle, hubs and brakes.

When I began with the Turtleback Trailer idea I had dreams of taking my years of off road fab work and building some super cool like nobody else had suspension system. Independent trailing arms, coil over shocks, lots of wheel travel. You know, an OFF ROAD TRAILER!

After the testosterone buzz wore off I got back to the reality of it all.

Here are a few realities with an off road trailer:

A trailer does not articulate, the hitch articulates.

It only has side to side pressures not to any corners. This means that a trailer does not need and shouldn’t have the wheel travel that your vehicle needs. If you have extended wheel travel your trailer will become unstable more easily and could end up on it’s top from the rebound from that travel.

If I have a bearing problem, spindle issue or suspension failure I need to be able to service it.

Having a trailer manufacturer’s proprietary suspension will make you at the mercy of that manufacturer or a welding shop somewhere out there to get you on the road. Time tested and true readily available parts will get me back on the road or trail and get me home.

How many hours and dollars is a fancy suspension worth, I’d rather have it in my pocket or on my trailer somewhere else.

If I were to build the suspension described in the first paragraph it would add an easy $1500 to the price of the trailer and frankly would be no where near the suspension we can get on the market with millions of proven miles under their belt.

Fancy is neat but I want to get there every time and get back home.


Here’s where our research took us:

We use the UCF Flexride patented suspension system. It’s stronger and more versatile than any other torsion axle system on the market today, period. Our axles are custom assembled for us using commercially available parts.

It starts with a USA made vulcanized rubber cartridge, not rubber tubes or rods. This cartridge is pressed into a 4” steel tube with Turtleback Trailers exclusive reenforced ends. The spring rate is set at 2750 pounds but using 3500 pound components to create a better ride for the trailers.

Next we install the Trailing Arm/Spindle on the splined boss from the cartridge. The splined assembly allows us to set the ride height of the vehicle to accommodate short 29” tires up to 35” tires on the same configuration and it can be modified at any time later on.

Then we put Dexter 10 drum brakes on the end with easy lube caps.

Now here’s the super cool part

The place where a trailer suspension is most likely to fail is the bearings. Sometimes if a bearing goes it can literally weld itself to the spindle. With most trailer suspensions you are SOL. With our system you can replace the spindle and trailing arm in about 20 minutes on a trail repair, use the spare greased hub and bearing that supports the tailgate put your tire back on and keep going. This repair brings the axle back up to 100 percent without compromise.

Call and ask me more, I love talking about this stuff.
