Features & Benefits

Hendrickson’s SOFTEK® NXT system combines the STEERTEK NXT axle and monoleaf spring technology with an advanced integrated clamp group design. This complete system saves up to 107 pounds compared to a traditional two-leaf spring and I-beam axle system.

The SOFTEK NXT system is designed for heavy-duty truck applications rated for 12,500 pound capacities. The advanced design captures characteristics of the traditional mechanical suspension while reducing weight to help increase fuel economy and payload capacity.
