## Customer Reviews

### ⭐⭐⭐⭐⭐ Just in time
*by F***9 on November 9, 2023*

Works great perfect fitment

### ⭐⭐⭐⭐⭐ Money saver
*by W***. on September 7, 2021*

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
*by G***K on December 7, 2012*

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.
