Three types of PTS Units

Power Train Savers®

Stop axle, differential and driveshaft damage with lifetime drivetrain over-torque protection!

Power Train Savers® are patented drivetrain protection devices which mount into an existing driveshaft. Once installed, these unique devices protect the drivetrain from over-torque damage that can ruin differentials, gears, axles and driveshafts. With a Power Train Saver unit installed, you won't notice a difference in performance until you encounter an over-torque situation. Then, our precisely calibrated Torque Fuses® shear before drivetrain damage occurs, while the unit design holds the driveshaft in place.

  • Prevent damage to gears and driveshafts
  • Avoid costly repairs to drivetrain components
  • Eliminate roadside and repair shop downtime

Industrial Series

Torque Capacity 5,500 – 35,000+ ft-lb

The Power Train Savers industrial series is designed to withstand constant use in extreme environments and protect power driven units and operators from the dangers of accidental over-torque. Each self-contained unit is custom built to specific torque and driveline requirements, and the variety of torque fuse options allow for fine-tuning to optimal torque range. If over-torque occurs, the calibrated torque fuses snap safely and cleanly to stop the shaft. Getting equipment back up and working is as simple as replacing the fuses – there are no damaged parts to repair or clean up.

  • Completely self-contained unit can be used in any shaft-driven application.
  • Bolt-in protection uses standardized DIN and SAE flange configurations.
  • Torque capacities range from 5,500 ft-lb to 35,000 ft-lb (higher torque ratings available).
  • Standard flange configurations go from 155mm to 465mm.

Marine Series

Torque Capacity 5,500 – 35,000+ ft-lb

Power Train Saver units for marine applications bolt directly into the output gear flange. In situations of prop bottoming, debris or cable contact, the calibrated torque fuses shear to immediately stop the prop, preventing damage to the prop as well as the transmission, gear and drivelines. These specially designed devices excel at protecting ferries, luxury boats, tug and “push” boats operating in extreme river and ocean environments.

  • Installs between the transmission and prop shaft on marine powertrains.
  • Torque capacities range from 5,000 ft-lb to 35,000 ft-lb (higher torque ratings also available).
  • Standard marine flange configurations go from 155mm to 465mm.
