Bought this to do the timing belt on my 2000 Acura TL. Crank bolt came off with my impact wrench so I didn't need it. A week later, the motor blew a head gasket. I bought a replacement motor, my impact wouldn't budge its crank bolt. With the engine on a stand, I got this tool out, attached it 1/2" breaker bar and short piece of pipe and wedged them against the floor. Put another 1/2" breaker bar, socket and 4' pipe on the crank bolt and still couldn't break it loose. Ended up with me and my dad, both 200lbs, hanging on a 6' piece of pipe to get the job done. Thanks some serious torque, and this tool took it just fine.
