Looks like H153 has even lower 1st, 2nd, 3rd gear ratios than previous versions.

This means the h153 would be the best suited for offroad use of all of them IMHO

I wonder if the input shaft is the correct length for a 1HZ/D/FT bell housing, or compatible with the shaft that is since they are different gear ratios. Seems like another cool option if so
