A pulley is a simple machine that makes lifting heavy loads a lot easier. A snatch block is really nothing more than a pulley encased in metal that increases the pulling power of the motorized recovery winch on the front of your Jeep Wrangler. The snatch blocks we sell are designed to handle several thousands of pounds. They weigh about ten pounds and can be attached to whatever your Wrangler is winched to. In addition to increasing towing power, snatch blocks also protect the working components of your recovery winch by reducing stress and strain on the motor and recovery line.
