SPEED JACK-5K A-FRAME (TRAILER GEAR BOX)

A SPEED JACK-5K A-FRAME (TRAILER GEAR BOX) is a heavy-duty trailer component designed to raise, lower, and support the front end of a trailer during hitching, unhitching, loading, unloading, or parking.

Its primary functions include:

• Lifting/supporting: Provides up to approximately 5,000 lb of lifting capacity, depending on the specific model.

• Trailer positioning: Raises or lowers the trailer tongue to align it with the tow vehicle hitch.

• Stabilization: Supports the trailer when it is disconnected from the towing vehicle.

• A-frame mounting: Designed for installation on the A-frame/tongue of a trailer, commonly used on utility, equipment, and other towable trailers.

• Gearbox operation: The internal gearing converts manual handle rotation into controlled vertical movement of the jack tube, making it easier to lift heavy trailer tongues.

• Load transfer: Helps transfer the trailer's tongue weight to the ground through the jack's foot or wheel assembly.
