Exact fit
I'm not going to lie, the driver side was a pain to put in. As far as the parts though, they fit great and seem durable. I save almost $300+ on parts alone. This isn't my first purchase from this website and it won't be my last.

Is this part greasable?
Rocky on Dec 23, 2016
BEST ANSWER: Most of our parts, based upon the manufacturer we receive them from will be pre-greased to avoid future greasing. In some cases however they will come with the grease fitting and you may apply grease whenever you choose.
