PowerStroke Drilling Jar

The PowerStroke drilling jar was engineered with Bowen technology to provide control, power, and flexibility for extended drilling periods in the most demanding applications.


We designed every aspect of this double-acting hydraulic jar to withstand the rigors and long hours of challenging applications. Featuring an extra-long stroke length for exceptional impact and impulse forces during jarring operations, the PowerStroke™ jar offers infinitely variable trip loads up to the maximum rating of the tool. Only a minimal load is required in both the up and down jarring directions, which is crucial in directional, horizontal, and extended-reach wellbores. This makes the PowerStroke jar an ideal solution for modern drilling operations.


  • Greater impact – Increased stroke length creates superior jarring forces
  • Precise control – Provides infinitely variable impact intensity in vertical and directional drilling
  • Proven, reliable performance: – Robust design with tens of thousands of runs
  • Flexible placement – Exceptional tensile and torsional strength ratings
  • Rig floor convenience – 30-ft length allows the tool to be racked back
