Gearwrench 84440 Impact Universal Joint 3/8 Inch Drive

Product Description

The GEARWRENCH 84440 is a 3/8 inch drive impact universal joint designed to extend reach and change working angles in confined or awkward fastener locations. Built to ASME standards, it accepts a 3/8 inch male drive input and delivers a 3/8 inch female drive output, with an overall length of 2-5/32 inches. The 84440 is intended for use with impact wrenches and ratchets and is a working tool for professional mechanics, fleet technicians, and trade professionals who need reliable articulation under torque without joint failure.

This universal joint is suited for automotive, heavy equipment, and general mechanical service applications where straight-line access to a fastener is not possible. It is a practical addition to any 3/8 inch drive impact or hand-ratchet setup when working in engine bays, undercarriages, HVAC equipment panels, or tight mechanical assemblies. The compact overall length keeps it maneuverable in restricted spaces.

Key Features

• 3/8 inch male drive input and 3/8 inch female drive output for direct integration into standard 3/8 inch drive sets
• Rated for impact use, providing durability under high-torque impact wrench operation
• Overall length of 2-5/32 inches for compact fitment in tight spaces
• Meets ASME standards for dimensional and performance compliance
• Backed by a limited lifetime warranty from GEARWRENCH

Compatibility

Designed as an OEM-style replacement and standard accessory for 3/8 inch drive impact and ratchet tool sets requiring a universal joint adapter.

Installation Notes

Installation requires no special tools beyond the existing 3/8 inch drive setup. Ensure the joint is fully seated on the drive square before applying torque. When used with an impact wrench, confirm all connections are secure to prevent joint separation under load. Inspect the joint periodically for wear, especially if used frequently at extreme angles.
