    I have a pair of QSB 420ho’s and I was wondering which is a better transmission for these, a ZF280A or a ZF 80A ??

    Thanks Tony. I have low hour 280A’s but a set of 80A’s came up and I was thinking about a backup set.

    Apples vs oranges–Not even in the same class — IMO, the 280A is a superior gear
