Professional Wet Kit Installations for Dump, Lowboy, and Detachable Trailers

Midco Sales offers complete wet kit installation and setup services for trucks that need hydraulic power to operate specialized trailers. Our service department installs and configures PTO-driven hydraulic systems (commonly called wet kits) for use with end dumps, side dumps, lowboys, Landoll traveling axles, detachable goosenecks, and live floor trailers.

Whether you’re equipping a new truck or upgrading an existing fleet, our technicians build each system to match your trailer’s specific hydraulic requirements — ensuring smooth operation, reliable pressure, and maximum performance.

What Is a Wet Kit?

A wet kit (or wet line system) is a hydraulic power system installed on a truck that allows it to operate hydraulic functions on compatible trailers.
Each system typically includes:

• PTO-mounted hydraulic pump
• Hydraulic tank and filtration system
• Control valve and hoses
• Return and pressure lines

Our shop installs single-line, dual-line, and three-line wet kits, depending on the trailer type and flow requirements.

Wet Kit Installations for Every Application

Midco Sales builds and installs custom wet kits for:

• End dump and side dump trailers – high flow systems for fast raise and lower valves
• Lowboy and detachable gooseneck trailers – two- and three-line hydraulic setups for smooth detaching and re-coupling
• Landoll and traveling axle trailers – precision-matched flow systems for tilt and winch functions
• Walking floor / live floor trailers – continuous-flow hydraulic circuits for dependable performance

We stock components from leading hydraulic brands and design each setup to match your truck’s transmission, PTO, and trailer type.
