In order to confirm the correct replacement landing gear leg for your trailer you'll need to take a few measurements, the first simply being the length of the outer tube. Then, you'll need to measure the distance between the weld stops either inside to inside or outside to outside. The weld stops are what keeps the brackets in position on the outer tube.

The most common replacement has a 29-1/2" long outer tube with 15-1/2" weld stop spacing inside to inside or 17-1/2" outside to outside. In which case, you'd use part # LG-179013 for the lead leg or part # LG-179014 for the follow leg. If the trailer has two motors, you'll need two lead legs. The correct replacement gear box and motor for the lead leg is the Replacement Gearbox part # RVLG-RDBOX and Lippert Venture 5th Wheel RV Landing Gear Motor part # LC142178.

I have attached our full list of replacement legs to choose from as well if the above won't work.
