## Customer Reviews

### ⭐⭐⭐⭐⭐ Doesn't Rub, Perfect Fitment.
*by C***S on March 25, 2025*

2015 M235 (N55) Doesn't rub at all. Some people have had that problem, there definitely is some wiggle room when mounting, just make sure to get it as center as possible and your crank seal is protected for a fraction of the price compared to Euro aftermarket brands

### ⭐⭐⭐⭐⭐ Good Fit
*by R***. on November 20, 2024*

It was a job. But I did it when I changed the tensioner pully. You're kind of blind when you trying to put the bolts back in the harmonic balancer. Nevertheless just what the doctor ordered

### ⭐ Rubbing
*by E***Z on April 22, 2025*

Rubs on crank pulley, loud noise. Will be needing to remove & to job over. N54
