Just as described
Received and installed yesterday, fit well, did not leak once installed, and seems to work well. It was very well packaged and the paint on the part seems good. Overall happy with the purchase so far, we will see it continues to work well.... if not I will update the review.

Good deal as long as you can use old pushrod, spring, and retainer
Good price for the item my biggest complaint was the fact it didnโt come with the pushrod, spring, and retainer. Had to reuse them from the old booster and Iโm not a fan of that.
