I couldn't find a specific answer to this question. I recently replaced my rear diff mounts with Innovative billeted 75A (2 of the OEM were blown so I replaced all 4). Are there any mechanical problems that can arise from having stiffer rear diff mounts but no where else? (Meaning, with hard acceleration can other components in the chain have a failure because of less give in the rear diff?)

thanks

 

No. If anything, stiffer mounts will save on drive train parts such as the propeller shaft due to less slack/play.
