If you've spent any time cranking a standard tongue jack by hand, you already know how slow and frustrating it can be, especially if you're working alone or dealing with a heavy load. The Trailer Valet JXC center mount jack addresses that problem directly by giving you a jack that works both manually and with a standard cordless drill. Here's a breakdown of what it is, how it works, and whether it makes sense for your trailer.

What Is the Trailer Valet JXC?

The JXC is a center-mount tongue jack that bolts directly to your A-frame tongue without welding. It comes in two capacity versions:

• JX2-C -- 2,000 lb static capacity, 1:1 gear ratio
• JX5-C -- 5,000 lb static capacity, 12:16 gear ratio

Both versions ship with a hand crank, a drill attachment, a footplate, and all the mounting hardware you need to get installed.

Manual or Drill Powered

The main selling point of the JXC is the dual-operation design. You can crank it by hand the traditional way, or attach any 20 to 24-volt non-impact cordless drill to run it automatically. That flexibility matters when you need precise final positioning by hand, but want to cover the bulk of the travel quickly with a drill.

Lift capacities break down as follows:

| Model | Static Capacity | Manual Lift | Drill Lift |

|-------|----------------|-------------|------------|

| JX2-C | 2,000 lbs | 1,200 lbs | 600 lbs |

| JX5-C | 5,000 lbs | 1,600 lbs | 800 lbs |

Note that lift capacity and static support capacity are different numbers. Static capacity is what the jack holds while the rig sits on it. Lift capacity is how much weight it can actually raise off the ground.

Physical Specs

Both the JX2-C and JX5-C share the same tube dimensions: a 57mm outer tube with a 51mm inner tube. Total travel is 14 inches, giving you a height range of approximately 9.5 to 23.5 inches from the bracket, or 23 to 37 inches in retracted to fully extended height. Combined weight of the unit is 14 pounds.

The mounting uses three bolts with lock washers into the center of your A-frame tongue. You need at least 16 to 18 inches of clearance underneath to install it properly.

Build Quality and Weather Resistance

The JXC is built with a zinc-rich steel construction, nickel plating, and a wrinkle black powder coat finish rated for 700 hours of salt spray resistance. That rating makes it a reasonable choice for boat hauling, though Trailer Valet recommends rinsing with fresh water after heavy saltwater exposure. The jack has three layers of weather protection and is designed to be stored outdoors on the trailer between uses.

The internal gear system is patented and designed to manage heat retention, which matters when you're running it repeatedly with a drill under load. Trailer Valet recommends greasing the internal gear system every 90 days to maintain smooth operation.

Built-In Safety Indicators

Both JXC models include warning and stop indicators on the inner tube at both the top and bottom of travel. These markers give you a visual signal before the jack reaches the end of its gear travel, helping prevent over-extension and gear damage.

What's Included and What's Not

Each JXC comes with:

• Hand crank
• Drill attachment (compatible with any 20 to 24V non-impact drill)
• Footplate
• Mounting hardware (three bolts and lock washers)

The wheel attachment (model TVJXMW) is sold separately. If you add the wheel, static capacity with the wheel drops to 1,200 lbs, so keep that in mind when sizing the jack for your trailer.

Which Model Is Right for You?

For light utility rigs, landscape units, or small enclosed trailers, the JX2-C covers most situations and offers a simpler 1:1 gear ratio that's easy to control manually. For heavier cargo units, car haulers, or any setup approaching 5,000 lbs tongue weight, the JX5-C is the right choice and its geared design gives it a mechanical advantage that the 2K version lacks.

If you're not sure which capacity fits your setup, the best approach is to check the GVWR and calculate roughly 10 to 15 percent of that as your expected tongue weight. Match that number against the static capacity of the jack, not the lift capacity.

Final Thoughts

The Trailer Valet JXC is a well-engineered upgrade over a standard manual jack. The drill-powered operation saves real time and effort, the build quality handles outdoor conditions well, and the bolt-on center mount installation keeps it accessible to anyone with basic hand tools. If you're spending a lot of time hitching and unhitching, it's worth considering.

Frequently Asked Questions

What is the Trailer Valet JXC center mount jack?

The Trailer Valet JXC is an electric-powered center mount tongue jack designed to replace manual hand-crank jacks. It uses a 12V motor to raise and lower the trailer tongue, making one-person hookup and parking significantly easier. The center mount design positions the jack under the trailer's A-frame for balanced lift without the swing-away arm common on side mount jacks.

How much weight can the Trailer Valet JXC lift?

The JXC is rated for a 5,000 lb tongue weight capacity with a maximum gross trailer weight of 30,000 lbs. This covers the majority of utility, cargo, flatbed, and equipment trailers in the light-to-medium duty range.

Does the Trailer Valet JXC replace a standard tongue jack?

Yes, it is a direct replacement for standard A-frame center mount jacks. Installation uses existing bolt holes on most A-frame trailers and does not require welding or frame modification. The JXC uses a standard 12V trailer battery or direct vehicle power connection.

What is the advantage of a center mount jack over a side mount jack?

Center mount jacks provide balanced lift directly under the tongue's centerline, which reduces lateral stress on the A-frame compared to offset side mount designs. They also eliminate the swing-arm mechanism that side mount jacks require, resulting in a simpler, lower-profile design that works better on trailers with narrower tongues.

Is the Trailer Valet JXC suitable for gooseneck or fifth wheel trailers?

The JXC is designed for conventional bumper-pull trailers with an A-frame tongue. Gooseneck and fifth wheel trailers use different coupler configurations and typically require purpose-built electric landing gear rather than a standard tongue jack.
