In order to find the correct replacement landing gear leg for a trailer you'll need to measure the outer tube and distance between the weld stops on the leg, either inside to inside or outside to outside. If they are 29-1/2" long and measure 15-1/2" and 17-1/2" then you can use the Replacement Lead Jack part # LG-179013 or Replacement Follow Jack part # LG-179014.
If you get another measurement please let me know what that is and I will see if we have another option. view full answer...
