⚙️ Choose Your Tongue Jack

This HOSS 7x14 is offered in two configurations. Pick the one that matches how you work using the Tongue Jack selector above — everything else about the trailer is identical.

• With Speed Driver Standard Jack: 10,000 lb spring-assisted drop-leg jack with the Speed Driver extension — run it up or down in seconds with a cordless drill. Purely mechanical: nothing drawing off the battery, and one less hydraulic circuit to maintain.
• With Hydraulic Power Tongue Jack: 12,000 lb hydraulic tongue jack that raises and lowers under its own power off the trailer's 12V system — no cranking, no drill, no bending over the tongue.

💪 Why Upgrade to the Hydraulic Power Tongue Jack

• Push-button hookup: raise and lower the tongue without touching a crank or reaching for a drill. If you hitch and drop several times a day, that time adds up fast.
• 2,000 lb more capacity: 12,000 lb versus the standard 10,000 lb jack — it isn't working at its limit under a loaded tongue.
• Built for loaded tongue weight: a fully loaded 14,000 lb GVWR dump puts serious weight on the jack. Hydraulic power doesn't flinch.
• Easier on your back: no cranking, no drill torque fighting you, no awkward reach past the HOSS BOX.
• Precise solo hookups: fine height adjustments happen at the touch of a switch when you're lining the coupler up by yourself.
• Uses power you already have: runs off the same 12V deep-cycle battery and NOCO charging system that feeds the telescopic hoist — no separate power source to manage.
• Works in the cold and the mud: no frozen or seized crank mechanism to fight on a January morning.
• Strong resale: a hydraulic tongue jack is one of the most-requested dump trailer upgrades and holds value at trade-in.

💡 Not sure which to pick? If the trailer parks on one jobsite and gets dropped once a day, the Speed Driver jack is plenty of jack. If you're hooking and unhooking repeatedly, running loaded tongues, or working alone, the hydraulic jack earns its keep in saved time and effort.
