Question:

I have two of these on my gooseneck trailer and have stripped out both of the TJD-12000-RODNUTs on them, so will be ordering them. My question is does the parts for the TJD2SP-12000SP-F interchange where I can also get a TJD-2SP-12900 GBX and make it a 2 speed Jack?

I do have an option for you but you can't install the Replacement Gearbox for etrailer and Ram 2-Speed Square Jacks part # TJD2SP-12900-GBX on a singe speed jack, the hole location for the cross gear shafts coming out of the jacks are different on a single speed vs two speed jack. If you wish to obtain two speed operation you must swap out the entire jack to the Square 2-Speed Jack part # TJD2SP-12000SP-F.
