What Makes an Axle-Less HD Suspension HD?

A regular-duty Axle-Less suspension is fine for highway driving…

But when your adventure/getaway involves something out of the ordinary, you’re going to need something a little more heavy-duty, like the beefed-up Axle-Less HDseries.

The heavier design of the HD series enables your trailer to endure the abuse of the world’s harshest trails.

So, what makes the Axle-Less HD suspension HD?

Well, for starters we’re going to have to take a closer look at the Axle-Less design. Here are the basic components:

  • Steel hanger
  • Control arm
  • Outboard arm
  • Spindle
  • Bushings
  • Jounce spring
  • Rebound spring

The seven items listed here are the essential components in every Axle-Less suspension.

In order to transform a regular Axle-Less suspension into an Axle-Less HD suspension, the following components must change:

Steel Hanger / Control arm

Let’s begin with the steel hanger and the control arm:

Both the steel hanger and the control arm – made from precision-cut metal – become larger and stronger.

In fact, almost every component increases in size and capacity.

Outboard Arm / Spindle

This includes the outboard arm and spindle.

Both the outboard arm and spindle increase in size in order to accommodate larger bearings, hubs, brakes, rims and tires.

Urethane Bushings

The urethane bushingsare larger in diameter in order to house the larger fasteners that hold the control arm to the larger hanger (frame bracket).

Jounce Spring / Rebound Spring

With the exception of the smaller, rebound spring, the jounce spring must be made larger and stronger. However, in order to maintain good ride quality, the jounce is made of a softer durometer. Even though the larger jounce is more powerful, the softer durometer cushions the ride for rough, off-road conditions.

Well, there you have it.

Needless to say, the heavier design of the HD series enables your trailer to endure the abuse of the world’s harshest trails.
