Tell us what you need
Before you order jacks
A few things to check so the part fits the first time, or just tell us what you’ve got and the parts team will spec it with you.
- Size to tongue weight
- A tongue jack is rated by lift capacity. Size it above your loaded tongue weight, not the trailer’s GVWR.
- Match the mount
- A-frame (bolt/weld-on), swivel, or drop-leg. Tell us how your current jack attaches.
- Check the travel
- You need enough lift to hitch level; goosenecks usually want a long-travel or two-speed jack.
- Electric or manual
- Electric jacks need 12V power at the tongue. We can wire it or supply a manual jack.

Jacks FAQ
- What capacity jack does my trailer need?
- Size the jack to the tongue weight, not the total trailer weight. Tongue weight on a bumper pull runs roughly 10–15% of the loaded trailer weight; gooseneck pin weight runs higher, typically 20–25%. Pick a jack rated comfortably above that number — an undersized jack is hard to crank and wears out fast.
- What's the difference between top-wind, side-wind, and electric jacks?
- It's where the effort comes from. A top-wind jack has the crank on top (simple, but needs clearance above), a side-wind cranks from the side (works under gooseneck necks and tight spots), and an electric jack raises the trailer at the push of a button off the trailer battery. Mounting style matters too — bolt-on, weld-on, and pipe-mount jacks aren't interchangeable without the right hardware.
- What is a drop-leg jack?
- A drop-leg jack has an inner leg that releases with a pin and drops most of the travel instantly, so you only crank the last few inches. On tall trailers and goosenecks that saves a lot of cranking. Pair any jack with a foot plate or caster sized for the ground it will sit on — a small foot sinks into gravel and soft ground.
