Features

Auto-Torq technology takes the guesswork out of axle fastener installation by eliminating complex processes and specialty tools required with current market axle fasteners.

Applies the optimum clamp load on the bearings every time to minimize bearing wear, resulting in the longest bearing service life.

There’s no need for the costly spacers, half-stand bearings and precision hubs that are necessary for “PreSet” systems—Auto-Torq does all the work. Auto-Torq is compatible with any industry hub manufacturer, but you can combine it with STEMCO industry-leading seals, bearings, and hubcaps to get an extended warranty on your wheel ends.

By eliminating the need for complex and repetitive steps, Auto-Torq enables a quicker install time that is done correctly for improved peace of mind.

Designed with an internal mechanism for optimal wheel bearing adjustment according to Society of Automotive Engineers (SAE) Recommended Practice J2535 for Wheel Bearing Adjustment and Optimal Bearing Life.

Integrated locking mechanism prevents backoff while still allowing for easy removal during annual inspections and maintenance.

With no clips, washers, keepers, snap rings, or screws involved, you can rest assured that installation is performed correctly. Auto-Torq eliminates most variables and sets optimum bearing adjustment automatically.
