You can't get it as a part from losi but you can get them on ebay as a complete unit. It would cost over 90 bucks to convert it. Look for it on jennys_rcsport or do a search for LST2 gear. Make sure you bid on the one for the LST2 not the aftershock one that she also sells. They don't like it when you post links to the ebay sale site.
I think you may be wrong. LOSB3411, LOSB3424 are the high gear parts and LOSB3410 and LOSB3420 are the low gear parts. I've got over 7 gallons on my stock parts and when and if they quit I'll upgrade to those parts. Most any place can order them or you can try the many online stores.
