Replacement Bolt-On Tongue Jack for Pole Tongue Trailer

Question:

I need to know what size snap ring is used on this jack. This looks like a standard size you use for this application. I have seen other jacks in different RV stores and the base plate seems to the same size. My base is welded to the tung of my trailer. The other day my Son moved the trailer and failed to stow the jack so he bent the base pin holes and now the jack sits crooked. I am afraid the jack will fail so replacement is in order. I will take a picture of the jack and try to attach it to this email. Thanks in advance.

I recommend that you replace the entire jack and mount since there is no way to know for sure that the mounting base (that is welded to the trailer tongue) is still strong enough. Even if not actually damaged from the incident, it could be old enough to have metal fatigue that makes a new jack the best option, as you noted.

Pro Series jack # PS1400300303 and the Bulldog # BD154107 that you referenced are both 200-lb-rated topwind jacks with a foot plate. Both offer 10-inches of lift, which appears to be what your original jack provides. Both bolt on to your trailer tongue (up to 3 x 4-inch tongues will work) using included hardware and brackets.
