Description

When your trailer jack pin goes missing or the chain breaks, you’re stuck dealing with a loose pin that’ll find its way into the weeds or under your trailer. This replacement pin and chain assembly puts everything back where it should be, so you can crank your trailer up and down without worrying about losing parts or having to hold onto that pin with one hand.

What You’re Getting

5/8-inch diameter by 3.5-inch long steel pin built to handle the load
Attached chain that keeps the pin where you need it
Direct replacement for Bulldog 170 Series jacks—no modifications needed
Sturdy construction that won’t bend under pressure or break when you need it most

Built for Real Farm Work

This pin fits the popular Bulldog 170 Series trailer jacks that you’ll find on hay wagons, grain carts, livestock trailers, and implement trailers around the farm. Whether you’re positioning a grain cart for harvest or setting up a hay trailer in the field, this pin keeps your jack connected and ready to work.

Made to Last

The steel construction handles the weight and vibration that comes with farm trailers. The chain is built to flex with the jack’s movement without breaking, and it’s long enough to keep the pin handy but not so long that it gets in the way when you’re cranking.

Good to Know

Installation is straightforward—just slide the pin through the mounting holes and you’re ready to go. If your jack has been without a pin for a while, check that the holes haven’t worn oval-shaped. A little grease on the pin threads helps it slide smoothly and prevents corrosion.
