Trailer jacks aren't sexy. They sit on the tongue, they get rained on, and most people only think about them when one fails in a parking lot at 9pm. After watching thousands of jacks come through our service bay, we have strong opinions about what to buy and what to walk away from.
What jack do you actually need?
The first question is capacity. The rule of thumb: pick a jack rated for at least 1.25× the tongue weight of your loaded trailer. Tongue weight is typically 10–15% of total trailer weight. So a 7,000 lb loaded boat trailer has roughly 700–1,050 lb of tongue weight, and you want a jack rated for at least 1,300 lb. Most owners under-spec here and then wonder why the jack fails after two seasons.
Capacity ratings on jacks are static (lifting straight up). If you're using the jack to compensate for an unlevel pad or a soft surface, real-world load goes up fast. Buy more jack than you think you need.
Manual or electric?
If your trailer is a flat utility, a small boat, or anything you hook up once a month and the tongue is light: a quality manual jack is fine. You're paying $40–$80 and you're getting decades of service.
If you're hooking up an RV or camper, or a heavy boat, or you have any back issues at all: just put an electric jack on it. The price difference is $250–$350. The labor savings on a single season of cranking is worth it. Most electric jacks have a manual override built in for when the battery dies.
Drop-leg vs. fixed
A drop-leg jack has an inner shaft that pulls down with a release pin, getting the foot to the ground fast without screwing the entire travel. On any trailer where you frequently hook up and unhook, a drop-leg saves serious time. They cost $30–$60 more than fixed-shaft jacks and pay for themselves in a season.
Fixed-shaft jacks are simpler and have one fewer thing to fail. For a trailer that lives hooked up 90% of the time, fixed is fine.
Our picks for 2026
Best electric tongue jack: Bulldog Powered Drive 4000
4,000 lb capacity, 18 inches of travel, integrated bubble level, manual override, weatherproof seal. Around $325. The cheapest jack we'd actually trust for a 5th-wheel-style camper or a heavy enclosed trailer. We've sold hundreds; warranty calls are vanishingly rare.
Best heavy-duty manual: Dexter / Bulldog Heavy-Duty Drop-Leg, 7,000 lb
For when an electric isn't in the budget or the trailer doesn't have power. Drop-leg, sidewind, dual-speed gearing. Around $130. This is the manual jack we put on our own service trailers.
Best budget pick: Pro Series Sidewind, 2,000 lb
If you're outfitting a small utility or boat trailer and just need a working jack, this is the right $50 spend. Don't expect 20 years; expect 5–8 years of light-duty service.
What we skip
Generic Amazon-special electric jacks under $200. The motor housings are not weatherproof, the gearing strips, and the manual override usually breaks first. We replace these constantly.
Cast aluminum jacks at any price. Aluminum is fine for the housing of a quality electric jack, but cast-aluminum jack stands fail in fatigue. Steel inside, period.
Top-wind jacks for tongue use. A top-wind is great for stabilizers under a trailer frame. As a tongue jack, the geometry puts your knuckles at the trailer body when you wind. Sidewind for tongue.
Installation notes
Most A-frame couplers and tongue tubes accept a 2-1/4" or 2-3/8" tubular jack. Measure before you order - there is no universal mount. If you're swapping from a weld-on bracket to a bolt-on swivel mount, do it; the bolt-on is faster to service and lets you swing the jack horizontally for towing.
When you install an electric jack, run the power lead in convoluted loom directly to the trailer battery, not piggy-backed off the trailer's 12V running-light circuit. The jack motor pulls 25–30 amps under load and will brown out anything else on the circuit.
