Westward 21WL70 Impact Extension
The Westward 21WL70 is a 3/4 inch drive impact socket extension built for mechanics and technicians who need extra reach on powered impact wrenches. Its alloy steel construction and black oxide finish handle the high torque of professional automotive and industrial fastening work.
4 Inch Reach for Tight Spaces
This 4 inch extension replaces shorter accessories when fasteners sit deep inside assemblies or behind obstacles. The jump is worth it whenever a standard socket or shorter extension cannot engage the bolt head without removing surrounding components.
Verify 3/4 Inch Drive Compatibility
Confirm that your impact wrench and sockets both use a 3/4 inch square drive before ordering. The extension matches SAE four-point dimensions on both ends, so mismatched drive sizes will prevent proper engagement.

Questions about this item
What drive size does the 3/4-inch square drive on the 21WL70 extension fit?
Both the input and output drives are 3/4-inch square, so the extension connects directly to any 3/4-inch drive impact wrench or socket.
How do you secure the extension to an impact wrench, and what step is often missed?
Slide the 3/4-inch square drive onto the wrench anvil until the detent ball clicks into the retention groove; the missed step is failing to verify the ball is fully seated before applying torque.
When should the black oxide finish on this alloy-steel extension be inspected or the tool replaced?
Inspect the finish and square drives before each use; replace the extension if the black oxide coating is worn through, the square drives show rounding, or cracks appear in the alloy steel body.
