View Husky 30774Husky A-Frame Tongue Jacks: Top-Wind, Side-Wind & Parts
A manual trailer tongue jack lifts the front of a trailer so you can connect or disconnect it from a tow vehicle, then supports the trailer at the coupler when parked. Husky makes several A-frame top-wind, side-wind and swivel models. They differ in rated tongue load, cranking position, extension travel and tube diameter, so a replacement should be chosen by the complete part number and dimensions—not simply by how similar the jack looks.
Husky jack diagrams and measurements
Husky's factory towing catalog (manual jacks, page 38) shows each part number, outer and inner tube size, stroke, and the extended and retracted dimensions measured from the mounting plate. That last point matters: overall jack height and usable clearance are not the same dimension. The manufacturer also shows the side-wind swivel jack separately from the fixed A-frame versions.
The images in the product cards below show the exact jack listings. Use the catalog drawing when checking how each model fits a particular A-frame.
Top-wind versus side-wind jacks
Top-wind: The crank is on top of the jack. This leaves the sides clear but needs room above the coupler for a full crank rotation. It is available here as the 1,000-lb 30774, 2,000-lb 30775 and 5,000-lb 30780.
Side-wind: The crank is mounted on the side. The fixed 30781 uses a vertical A-frame mounting arrangement but moves the handle to the side. The 30655 is a separate swivel jack with a wheel that pivots horizontally for travel; it is not a straight replacement for a fixed A-frame jack.
Compare capacity, stroke and tube diameter
| Part number | Handle style | Lift rating | Stroke/travel | Outer tube |
|---|---|---|---|---|
| 30774 | Top-wind | 1,000 lb | 14-7/8 in | 2 in |
| 30775 | Top-wind | 2,000 lb | 14 in | 2-1/4 in |
| 30780 | Top-wind | 5,000 lb | 14-1/2 in | 2-1/4 in |
| 30781 | Side-wind | 1,000 lb | 15-3/8 in | 2 in |
| 30655 | Side-wind swivel jack with wheel | 1,000 lb | 10 in travel | 2 in |
For fixed A-frame models, the manufacturer gives these heights from the mounting plate: 30774 retracts to 8½ inches and extends to 23⅜ inches; 30775 retracts to 9¼ inches and extends to 23¼ inches; 30780 retracts to 11 inches and extends to 25½ inches; and 30781 retracts to 8⅞ inches and extends to 24¼ inches. These measurements are not the same as the full jack body height above and below the tongue.

View Husky 30655Bulk-pack jack numbers and replacement caps
Husky also uses different numbers for bulk-pack versions of some A-frame jacks. These numbers identify the correct supplied model and packaging; do not assume the quantity or included accessories are identical just because the capacity matches.
- 88126 — 1,000-lb top-wind version.
- 88127 — 2,000-lb top-wind version.
- 88128 — 5,000-lb top-wind version.
- 88130 — 2,000-lb side-wind version.
For the side-wind jack tops, Husky lists 88131 as the cap for its 1,000-lb side-wind family, and 88132 for its 2,000-lb side-wind family. These are replacement caps—not load-bearing extensions or complete jacks.
Before selecting a replacement tongue jack
- Check actual tongue load. The jack must support the loaded trailer tongue. A 5,000-lb jack rating is not a 5,000-lb trailer towing rating.
- Measure the A-frame opening. Confirm the outer tube diameter, mounting-plate dimensions and bolt pattern. Top-wind and side-wind handles require different clearance.
- Measure the working heights. Check ground distance in the trailer's parked position, the coupling height and the retracted ground clearance when towing.
- Confirm the mounting type. A fixed A-frame jack is not interchangeable with a swivel side-mount jack without the required bracket arrangement. The trailer manufacturer must approve the location and method of attachment.
- Use a suitable footplate or wheel. Check the inner tube diameter and retaining-pin arrangement. Husky recommends a foot pad with the 5,000-lb top-wind jack; a wheel rated below the tongue load must never be substituted.
Husky’s catalog illustrates the grease fitting used for routine maintenance. Support the trailer securely before inspecting a jack, keep hands clear of the moving tube and crank mechanism, and do not use the jack to lift a trailer for underbody service or tire replacement.
For parking stabilization rather than tongue lifting, see our Husky scissor stabilizer comparison. Those stabilizers have different jobs and must not replace a tongue jack.
