SOFTEK® combines Hendrickson's MONOLEAF™ steel spring and the rigid, box-shaped STEERTEK axle for outstanding ride and stability with substantial weight savings.
As the industry's leading supplier of heavy-duty springs, Hendrickson drew on decades of engineering expertise in developing the MONOLEAF spring used in the SOFTEK system. This innovative single-leaf spring technology reduces weight and eliminates inter-leaf friction.
SOFTEK utilizes Hendrickson’s fabricated STEERTEK axle, which is designed to increase stability and handling, and reduce weight. The unique manufacturing process allows greater design flexibility to meet the varied applications in the industry.
In capacities up to 6.6 t, SOFTEK incorporates features to help reduce maintenance costs. Integrated steering arm and tie rod attachments increase strength and reduce weight, while the two-piece knuckle assembly simplifies kingpin bushing serviceability.

More road time
Box-shaped STEERTEK axle resists horizontal, vertical and twisting forces better than I-beam axles reducing wear on vehicle and increasing steer tyre life
Rubber bushings help reduce maintenance and noise
Two-piece knuckle assembly reduces time required for servicing kingpin bushings
MONOLEAF springs reduce vibration to cab, chassis, engine and electrical components
