Gearwrench 86524 17 Pc Impact Extension Bar Set

Product Description

The GEARWRENCH 86524 is a 17-piece impact extension bar and universal joint set covering 1/4 inch, 3/8 inch, and 1/2 inch drive sizes in inch measurements. The set includes extension bars and universal joints purpose-built for impact tool use, with a black tool finish that resists corrosion and wear in shop environments. All pieces are tether capable, making this set suitable for work at height or in environments where dropped-tool protocols are required. The kit stores in a precut foam tray housed in a plastic case, keeping every piece indexed and accounted for at the end of a job. Total set weight is 7.92 pounds.

This set is suited for automotive, fleet, and general mechanical service work where multiple drive sizes are needed across a single job. The combination of 1/4 inch, 3/8 inch, and 1/2 inch extensions and universal joints covers the range of fastener access situations encountered in engine bays, suspension work, and drivetrain service. The tether-capable design makes it appropriate for elevated work platforms, lift bays, and any facility with a tool-drop prevention policy. Professional mechanics and fleet technicians are the primary installers.

Installation Notes

Impact extension bars and universal joints should be inspected for cracks or deformation before each use and removed from service if damaged. Always match the drive size of the extension or joint to the drive size of the impact tool and socket. Do not exceed the rated torque capacity of the drive size in use. Tether attachment points should be used in conjunction with a rated tool lanyard when working in elevated or overhead positions.
