The Martins Industries MFJ-E Floor Jack Extension is the smart, safe solution for lifting high-clearance vehicles. Engineered specifically for use with Martins Floor Jacks (models MFJ-P2T, MFJ-PL2T, MFJ-3T, and MFJ-P3T), this heavy-duty steel extension adds a full 3 inches of extra lift height, enabling your floor jack to reach maximum lift heights of up to 24 inches depending on the jack model. Perfect for lifted trucks, Jeeps, and other vehicles with elevated jacking points, the MFJ-E is built to handle up to 6,600 lbs and installs securely with its M20 x 1.5 x 12 mm threaded connection—providing rock-solid stability you simply can't get from makeshift solutions like wood blocks, metal shims, or hockey pucks.
When working with lifted vehicles or high jacking points, many technicians resort to improvised height solutions—but those can be unsafe, unstable, and unreliable. The Martins MFJ-E Floor Jack Extension eliminates the guesswork and risk. This purpose-built accessory is designed to integrate seamlessly with Martins floor jacks, threading directly into the saddle for a secure, precision fit. With its robust steel construction and 6,600 lb load capacity, this extension is engineered for professional use in busy automotive shops and serious home garages alike.
Installation is quick and straightforward: simply unscrew the bolt under the pad of your jack's saddle, remove it, screw in the MFJ-E extension, and place the saddle back on top. In just three easy steps, you've added 3 inches of lifting height—safely and securely. The threaded design ensures the extension stays locked in place under load, providing the confidence you need when working beneath a vehicle.
Watch how the Martins Floor Jack Extension installs and performs with Martins floor jacks.
The MFJ-E is precision-machined from high-strength steel and finished in a durable grey coating to resist wear and corrosion. Measuring 3 1/4" x 3 1/4" x 2" and weighing just 2 lbs, this compact extension adds capability without adding bulk. Its compact footprint and lightweight design make it easy to store in your tool chest or on a shelf until you need that extra lift height for a tall truck, SUV, or custom-lifted vehicle.
Unlike improvised extensions that can slip, compress, or fail under load, the Martins MFJ-E threads directly into your jack's saddle assembly, creating a mechanical lock that won't budge. This is hands down the safest, most reliable way to extend your floor jack's reach—eliminating the hazards associated with stacking wood blocks or hockey pucks under the saddle.
