How fleets can
benefit from today's

6x2 axle
configurations

Improved designs and increased availability
of liftable pusher axles are making the
6x2 a more viable option for fleets.

he 6x2 axle configuration has been around for
decades. Just ask Joel Morrow. His family's trucking business has been using both 6x4s and 6x2s
for 40-plus years. Nowadays, Morrow has come
to prefer a 6x2.
"I have learned all the little quirks over
the years," says Morrow, senior driver and
head of research and development for Ploger
Transportation in Norwalk, Ohio. "Now I prefer
6x2s, even in snowy weather. You can actually

get better traction as long as you understand the
aspect of weight distribution."
Traditionally though, traction has always been
one of the generally accepted downsides of a 6x2,
notes Morrow. With a 6x4, both rear axles are
powered axles which helps with traction, whereas a 6x2 has only one of the rear axles powered.
Additionally, a 6x4 provides more power and
torque since both rear axles are receiving power.
Resale value is another reason why some fleets
have shied away from 6x2s. Since 6x4s continue to
outsell 6x2s by a wide margin, there isn't a terribly
large market for used 6x2s.
All of those factors have continued to thwart
the more widespread adoption of 6x2 axle configurations. However, 6x2s offer a couple of unmistakable benefits where many fleets are placing
higher levels of importance: fuel economy and
weight. Additionally, new design approaches and
the leveraging of technology are making certain
6x2 configurations more functional, versatile, and
cost effective.
"For fleets that really pay attention to the
details and work with OEs and tire manufacturers to get the best configuration for their

		┬╗Link Manufacturing's 6x2 liftable axle is commercially
available on Volvo and Mack trucks. The company will
be introducing its own version later this year for possible
inclusion on additional brands. This 6x2 pusher features
adaptive loading technology which automatically
distributes load to the drive axle in instances where traction
must be enhanced; no driver intervention is needed.

operation, the 6x2 axle is a real opportunity
going forward," says Joel Van Den Brink, senior
engineer for Link Manufacturing, a manufacturer of suspension systems including lift axles for
commercial vehicles.
