Short Summary
With hundreds of thousands of HT™ Series suspensions on trailers running on- and off-road, these models have been the suspensions of choice throughout the world in virtually every trailer application for nearly a decade.

The HT Series delivers rugged dependability and outstanding ride quality and control for curtainsiders, platform trailers, tippers, tankers, low loaders, car transporters and container chassis.

Our patented TRI-FUNCTIONAL® Bushing in unison with a rigid beam and solid axle connection provides the ideal combination of ride softness and roll stability. With only two long-life bushings for each suspension, HT suspensions provide a straight-forward, functional design with few parts to minimise maintenance.

Available with disc or drum brakes, HT axle suspension systems supply responsive, consistent braking power in a reliable and durable package. In addition, standard QUIK-ALIGN® provides fast, easy, accurate axle alignment using standard tools.
