Stillwell Inc Hydraulic Trailer Jacks, Cylinders & Parts

Stillwell Inc is an active manufacturer founded in 2007, headquartered in Burnsville, Minnesota, with steel fabrication and hydraulic production in the Cleburne and Fort Worth, Texas area. The company builds hydraulic systems and steel-fabricated components for trailers and mobile equipment: hydraulic trailer jacks, welded, tie-rod, and telescopic cylinders, hoses, manifolds, valves, and scissor hoists for dump trailers. Northern Hydraulics supplies Stillwell hydraulic products, including trailer jacks, cylinders, hoses, manifolds, valves, and conversion kits for customer applications.

Stillwell Product Lines & Series

Stillwell’s hydraulic trailer jacks are organized by lift capacity and base configuration:

• Atlas — 10K lift-capacity hydraulic trailer jack.
• Tradesman — 7K lift-capacity hydraulic trailer jack.
• Duro — 12K lift-capacity hydraulic trailer jack.
• Vaquero — self-contained hydraulic jack system, configurable on an Atlas or Tradesman base.
• Scissor Hoist — hydraulic hoist line for dump trailers.

Beyond the jack families, Stillwell produces welded, tie-rod, and telescopic cylinders alongside SAE 100R17 hose assemblies, sold here through the hydraulic jack and power-unit range. The line also includes hydraulic manifolds and valves. Jacks and hoists are customizable for bolt-on or weld-on installation on most gooseneck and bumper-pull trailer types.

Cross-Referencing Stillwell Parts

Stillwell builds to application-specific compatibility rather than a published interchange list, so matching an aging or discontinued jack, cylinder, or hoist starts with the configuration on your trailer — lift capacity, base series, stroke, and bolt-on or weld-on mounting. We cross-reference Stillwell trailer jacks, conversion kits, manifolds, and cylinders to the correct current Atlas, Tradesman, Duro, or Vaquero equivalent, and spec replacement and equivalent parts when a model number is faded or no longer cataloged. If you have a Stillwell part number, a worn tag, or a measurement off the unit, send it over and we will identify the equivalent part. Request a Stillwell cross-reference quote.
