Frequently Asked Questions
How does this torque extension compare to using a standard torque wrench?
This extension works with impact wrenches for high-speed operations while automatically limiting torque to 475 ft-lb. Unlike manual torque wrenches that slow workflow, it maintains pneumatic tool speed with consistent torque control for high-volume shop environments.
Will this work with all 3/4-inch drive impact wrenches?
Yes, both ends are standard 3/4-inch drive size for universal compatibility with pneumatic and electric impact wrenches. The chrome molybdenum steel construction handles high torque output while providing consistent 475 ft-lb limiting across different wrench brands.
Does the 475 ft-lb rating require recalibration over time?
No, the extension is pre-calibrated and maintenance-free throughout its lifetime. The chrome molybdenum steel construction maintains precise 475 ft-lb limiting without recalibration, eliminating ongoing calibration costs and downtime for busy shop operations.
What types of vehicles is this torque extension best suited for?
This 475 ft-lb extension is designed for heavy-duty trucks, trailers, commercial vehicles, and large equipment where precise torque control prevents component damage. Ideal for fleet maintenance and commercial shops working on larger wheel assemblies.
