what size tounge jack is on a 14000lb pj trailer

A 14,000 lb PJ trailer is commonly paired with a 12,000 lb drop-leg jack , and PJ’s own trailer materials show 12,000 lb and 10,000 lb jack options depending on the model and setup. For a 14,000 lb trailer, the important part is the tongue weight , not the full trailer rating; a jack should exceed the tongue weight with some margin, and industry guidance often puts tongue weight around 10–15% of trailer weight.

Practical answer

• If you’re asking what to replace it with, 12,000 lb is the safe common choice for many PJ 14k trailers.

• If you want the lightest adequate size, a jack above 2,500 lb can technically handle the tongue weight estimate, but that leaves less margin and is not the usual heavy-duty trailer choice for this class.

• If your trailer has a gooseneck setup, the jack style may differ from a bumper-pull tongue jack.

What to verify

• Check whether your trailer is bumper pull or gooseneck.
• Look for the existing jack’s capacity stamp on the jack tube or footplate.
• Match the mount type and height range , not just the weight rating.

Simple rule

For a 14,000 lb PJ trailer, 12,000 lb jack capacity is a solid bet unless your exact model uses a different setup.
