Replacing Lippert Components 3500 lb Powered A-Frame Trailer Jack w/ Stromberg Carlson  

Updated 05/30/2026 | Published 07/23/2016

Question:

I would like to replace my current tongue jack with one of these. My current jack is rated at 3500 but I want to increase that to 5000. My concern is the bolt pattern at the flange. Will this match up? Thanks for your help.

It looks like you currently have a Lippert # LC285318. The 5000 lb capacity Stromberg Carlson # JET-5000 has mounting holes that are compatible with the industry standard 3 inch bolt spacing, but the holes are also slotted to match up with different mounting hole patterns.

I am looking to replace the same Lippert jack on my travel trailer. However, I am curious if the Stromberg jack is compatible with my Lippert GroundControl 3.0 auto leveling system.
