This is the response I got from Dorman:
Thanks for your inquiry. Sorry we do not produce any hoists or their parts.

Good day,
Just saw that this is now available. The description mentions that it is coated to prevent corrosion. The main problem with the originals is the secondary latch failing to release due to corrosion. Has this been addressed with this hoist? The only way I can see that this can be prevented is by making the secondary latch out of stainless steel.
Thanks.
I did put THEIR part number in the subject line.
