Extended 40 in. length, 50% longer than standard, give you extra leverage and makes your job easier. The Chrome Vanadium body is paired with a Chrome Molybdenum head, making for an extremely strong and durable breaker bar. The sockets are kept firmly secure by the spring loaded ball bearing. The head rotates 230-degree to provide you with dynamic options for a variety of jobs.
