Ingersoll Rand Air Impact Wrench Kit | 131K-LA | 600 (ft-lbs) Torque | 1/2" Square Drive

For automotive repairs, fleet maintenance, and everyday workshop fastening, the Ingersoll Rand 131K-LA Air Impact Wrench Kit combines reliable pneumatic power with a convenient socket and storage package. This 1/2" square drive impact wrench delivers up to 600 ft-lbs of maximum breakaway torque (loosening force for stubborn fasteners), making it suitable for tire service, suspension repairs, and general mechanical maintenance. Its twin-hammer clutch mechanism uses two balanced hammers to deliver consistent impacts while reducing harsh vibration. A steel front hammer case protects the impact mechanism, while the lightweight composite rear housing makes the wrench practical for repeated shop use.

With a working torque range of 25–350 ft-lbs and 8,000 RPM free speed, the 131K-LA supports efficient tightening and removal of common automotive and equipment fasteners. The multi-position forward/reverse throttle configuration provides adjustable power control, helping technicians match tool output to the task. Operating at 90 PSI with an average air consumption of 4.2 CFM, the wrench works with an appropriately sized compressed-air system. Weighing 5.8 lbs and measuring 7.3" long, it offers manageable handling for professional service work. The kit includes four deep impact sockets and a blow-molded carrying case for convenient organization and transport.
