Find Your Jack
At Trailer Gearbox, we know trailers. We have owned, maintained, and worked with hundreds of trailers across real hauling, equipment, and trailer-based businesses. We built Trailer Gearbox because we saw the same problem over and over again: hand-cranking a trailer jack SUCKS! It is slow, frustrating, and physically demanding.
Whether you are hooking up in bad weather, raising a loaded gooseneck trailer, leveling an equipment trailer, or trying to avoid unnecessary strain on your shoulders and back, the right drill-powered trailer gearbox can make the job significantly easier.
This guide will help you choose the correct Trailer Gearbox system for your trailer jack configuration, mounting style, and application, so you can buy with confidence and get the right fit the first time.
What are Speed Jacks?
Speed Jacks are designed to replace the bolt on jacks that are commonly seen on car trailers, boat trailers, small-medium size equipment trailers and enclosed trailers. There are many different mounting styles such as A-Frame, clamp-on and swivel mounts. Our drill powered jacks replace the manual cranking of your handle with a gear reduction system that allows you to raise and lower your trailer with a cordless drill.
Applications
Dump Trailers
Raise, lower, and reposition dump trailers faster with a drill-powered Speed Jack. Ideal for owners, rental fleets, and operators who want less manual cranking and easier trailer handling.
Equipment Trailers

Stock Trailers

Enclosed Trailer
Make enclosed trailer hookups faster and easier with a drill-powered Speed Jack. Ideal for cargo trailers, contractor trailers, and mobile business setups where quick, low-effort trailer handling matters.
Configurations
A-Frame Jack
A-Frame Jacks are the most common jacks found on small to medium sized trailers. They have a standard 3 hole bolt pattern, and are bolted in just behind the receiver on the trailer tongue. Installation of your A-Frame Speed Jack is as easy as removing the foot of your old jack unbolting and sliding it out of the trailer. Simply reverse the process to install your Speed Jack.
Frequetly Asked Questions
What Kind of Drill do I need? Can I use an Impact?
What Kind of Drill do I need? Can I use an Impact?
We recommend using an 18v or larger cordless DRILL, and setting your clutch to the highest setting. This prevents unexpected kickback or damaging your jack or gearbox in the event you bottom out your jack to the end of travel.
For most general purposes a 2ah Capacity is plenty for multiple up and down cycles. If you plan to go long periods between charges or load/unload very heavy trailers frequently throughout the day a larger amp hour battery will give you more runtime.
WE DO NOT RECOMEND USING AN IMPACT OR IMPACT DRIVER ON YOUR GEARBOX! Impacts are designed to transmit extreme shock loads to what they are driving in order to break things free or drive them home. While that impact is adverse to your gearbox, it is also being transmitted to the internals of your jack that was never designed to hold up to that kind of stress. A cordless drill delivers smooth controlled torque, that is multiplied by your gearbox and safely delivered to your jack.

Generally speaking, your gearbox is replacing you as the source of power for cranking your trailer jack. A good rule of thumb is if an able bodied person can crank the handle manually, a Trailer Gearbox can as well.
The Speed Jack 5k A-Frame is rated at 5,000lbs of static capacity and 3,000lbs lift capacity.
