Money saver
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.

gears
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.
