Steer Axles –
There is no comparison.
Spicer ® medium- and heavy-duty steer axles
host a number of patented design features to
keep vehicles out of the shop and on the road.
The Right Steer Axle
for Your Application.
Spicer ® Steer Axles improve
vehicle performance, whether it’s
on-highway, city delivery or bus chassis
applications. The exclusive combination of larger
kingpin bushings and a kingpin sealing system helps
ensure long service life and reduced maintenance.
In addition, the unique two-drawkey and spring
washer kingpin retention system, along with a
robust beam forging design, provides improved
vehicle alignment capability and axle durability.
A full lineup of steer axles is available in both
traditional and wider tracks to improve steering
under a variety of driving conditions.

Compressible
Insert
Compressible Insert vs. Open Cavity
The Spicer steer axle design excludes contamination
and retains grease far better than competitive
designs. This is accomplished through a patented,
compressible insert that prevents pressure and
vacuum typically found in competitive steer axle king
pin joints. The result is better lubrication retention
and reduced contamination of the kingpin joint for
longer life and trouble-free performance.

Keys
Dual Draw Keys vs. Staggered Draw Keys
A patented dual draw key system helps to improve
tire life by reducing tire wear more effectively than
conventional draw key designs. The dual draw key
system provides improved and more consistent
alignment of the kingpin with the beam to eliminate
unnecessary tire wear over the life of the vehicle.

Long-life Tie Rod Ends vs. Other Tie Rod Ends
Through patented purge valve technology, Dana’s
long-life tie rod end reduces contamination for
greater ball joint life than conventional designs.
The one-way design allows excess grease to
purge, while preventing contaminant intrusion.
Conventional designs include “holes” or “slots”
in the boot to allow excess grease to escape,
but can also permit entry of
damaging contamination.

Design
Patented “Power Rib” Beam Design vs.
Other Beam Designs
Improved strength, torsional stiffness, and beam
deflection are the key differentiators of Dana’s
“Power Rib” beam design. The patented beam design
allows Dana to offer a lighter weight axle while
maintaining superior strength. Greater torsional
stiffness and reduced beam deflection aids in improving
tire wear by maintaining better contact with the
road under heavy load conditions and higher torque
from hard braking.
