Frequently Asked Questions

Which torque limiting extension set is best for automotive work?

This 5-piece set covers the most common automotive torque specifications from 65-140 ft/lbs, making it ideal for passenger cars, light trucks, and SUVs. The spring steel design provides more consistent results than basic torque sticks for professional and DIY use.

How does this compare to torque sticks?

Unlike basic torque sticks that rely on torsional flex and user experience, this set uses calibrated spring steel that provides more predictable torque limiting. The color coding and laser etching also make it easier to select the right torque value quickly.

How do torque limiting extensions work?

Each extension uses calibrated spring steel that flexes and stops transferring torque once the preset value is reached. Unlike basic torque sticks, these provide consistent, repeatable results without relying on user feel or experience.

Are these accurate enough for professional use?

Absolutely. The spring steel design provides consistent torque limiting that meets professional shop standards. Many tire shops and service centers rely on torque limiting extension bars for their daily wheel work.
