Optimized Product Title

JET 1/2-Inch Drive 5-Inch Heavy-Duty Impact Socket Extension Bar (682954) | Used, Great Condition | SAE 4140 Cr-Mo Industrial Impact Extension Rod

Power through tight machinery clearance gaps and deep wheel wells with uncompromised impact torque. Upgrade your high-torque air and cordless setups with this used JET 1/2" Drive 5" Impact Extension.

Designed to withstand the punishing torsional shock loads of 1/2-inch pneumatic and cordless impact wrenches, the JET 682954 1/2" Drive x 5" Impact Extension Bar delivers direct, efficient power transfer to the fastener head. Featuring a 5-inch length, it provides the essential clearance needed to bypass suspension components, brake calipers, and frame rails without sacrificing rotational force.

This item is in excellent, fully functional used condition. Forged from premium SAE 4140 Chrome Molybdenum (Cr-Mo) high-impact steel, the square drive ends are clean and crisp with zero rounding, wall spreading, or internal cracking. The spring-loaded retaining ball on the male anvil functions perfectly to lock impact sockets securely in place. It displays normal, light cosmetic shop wear—such as minor surface scuffs, faint finish scratches, and light tool-box contact marks—with complete structural integrity.
