7100 rear lower mount question

[RonL]

I have heard that with 7100(400/100), that the stock lower rear mounts(D1) will not handle this valving?(bend/break)
Is this true?
Does any one have pictures of their heavy duty mounts?

yeah they will fail after some good pounding.

you can cut the cup off and then redrill the hole farther back in from the front and that should fix it.

others have also dropped in a new bottom plate and welded it in place to prevent the bottom plate on the stock mount from bending and then breaking.

It doesent take 7100 to make them fail either but with the 400/100 it happens pretty fast.
