I didn't know for sure what brand they sent me when I installed my Sachs kit, but they haven't stood up well at all. With about 60K miles on them they have sagged badly and are showing cracks with the result that the front end rides way too low.
The frustrating part is that when I did the Sachs kit I replaced the factory shock mounts not because they were worn or showing signs of age, but because they had 140K miles on them and I thought it was time they were replaced.
Please post if you find a source for some other brand that is OEM.
