Bilstein rear shock bushing bulging and cracking

I recently installed a new pair of Bilstein B6 4600 front and rear shocks on my 2004 Toyota Tacoma standard cab. Today I noticed that the bushings were bulging out and cracked. I torqued them to specs and I was wondering if anyone has had the same issue. Could it be an alignment with the upper mount issue? Thanks

 

Looks like it’s just bad rubber. I’d hit the manufacturer up for a replacement, send them the photo and details

 

I already did, waiting to hear back from them. Thanks for your feedback.

 

Did this happen on both sides, or just the one in the photo? Just curious.

 

Both sides.
