Ranger is an industry leader in aftermarket ST-80 repairs, parts, and upgrades.  The NOV ST-80 Iron Roughneck has been a popular choice for drilling contractors over the years and is an effective tool if maintained properly.  

Ranger offers complete in-house repair and recertification services to get your ST-80 back to new, or even better.  We have also developed upgrades and modifications to the OEM tool to increase performance and longevity of the ST-80.

Ranger is equipped to offer full CAT IV overhauls including machine work, crack weld repairs, NDT, paint, and pressure/torque testing.  We also offer exchanges on reconditioned sub-assemblies such as the upper jaws, lower jaws, transmissions, cylinders, valves, manifolds, and gauges.
