500106 Bevel Sidewind Gear Kit Trailer Jack Replacement Part for Bulldog Trailer Jack Models 139, 159 and 170 Series, For Up to and Including 5,000 lbs. Capacity Models

Works great perfect fitment

Was told by the dealership that our 5th wheel jacks were too old to repair, that they would need to be replaced. Found out that a couple of splines had broke in the old gears. With some work, they were replaced with this kit, and the "old" jacks work like new. Saved us hundreds of dollars.

They fit like a glove. Next time put in the specs. how many teeth are on the gears. The name on my trailer jack had worn off and I purchased these on a guess and it paid off.

Needed to replace our hand crank jack for our trailer and fit perfectly

The replacement worked, although I did have to switch the pin to fit the hole on my camper.

Fixed jack

This is misrepresented, it does not fit models below 5,000 lbs.

Worked great to replace gears in landing jack on camper.
