Built for Real Farm Work
This kit fits Bulldog 170 series jacks rated for 5000 pounds – the workhorses you’ll find on hay trailers, equipment trailers, and stock trailers around the farm. Whether you’re loading round bales, hauling the tractor to the back forty, or moving cattle panels, these bearings handle the load that comes with real farm work.
Made to Last
Trailer jacks take abuse from weather, dirt, and heavy loads. These thrust bearings are built to handle the constant up-and-down pressure while keeping things turning smooth. Quality materials mean they’ll keep your jack operating properly through seasons of use.
Good to Know
Rebuilding your jack is usually a straightforward job for anyone comfortable with basic mechanical work. Clean out all the old grease and grit before installing the new bearings, and pack everything with good quality bearing grease. It’s a lot cheaper than buying a new jack and you’ll know it’s done right.
