This tensioner was removed from a brand new vehicle which had performance modifications added. As a result, it no longer needed the OEM Factory parts. Parts are in excellent condition with minimal evidence of use. OEM, not a cheap aftermarket replacement.

Please compare to your original to ensure this is the proper part you are needing.
