Review on High-Torque Truck Extension Bar: Sunex 4330TE, 3/4-Inch Drive, 475 Ft/Lbs by Patrick Arnautov

Bought to tighten the eyelets on my semi trailer when realigning the wheels after service. Works perfectly. Just remember NOT to use this on battery power at the highest settings. The lever needs time to spring back to prevent excessive torque and my Milwaukee 2864 hits the highest setting too quickly resulting in excessive torque. Use the next lower setting instead (depending on which model you have) and when it stops spinning, you're done! If you're using an air shot, the "high" setting should be fine, as the air shots hit much slower and allows the club to flex properly between shots.
