GM Genuine Parts 178-0911 (23135220) Power Brake Booster Assembly

Exactly as described, best price I found online.

Part arrived missing a stud for the master cylinder mount. It was a defective part. After a long process with the seller and Amazon, nothing has been resolved. They kept my money and I'm left with a defective part. Do not order from this provider. Buy elsewhere.

priced right

After I got it just about all the way installed, I went to install the master cylinder and it turns out one of the bolts for the master cylinder wasn’t seated correctly in the booster, and I had to spend the next four hours trying to fish it out to get this installed. I would’ve returned it, but I already spent so much time on it. It shouldn’t of left the warehouse like this. This isn’t something to happen in transit.

Buyer beware, with any Amazon store read description carefully if it says OEM please be sure that it is actually OEM not OEM aftermarket Chinese crap that is not make to exacting specifications and they make up the difference in adapters or gaskets. READ DESCRIPTIONS CAREFULLY they can be deceptive and make you think that you are buying OEM when it is actually NOT. I will not use this seller again for this reason, deceptive description.

Bolts that master cylinder screw on were loose inside of booster rolling around.

Cheaply made won’t fit as described and they wouldn’t refund. Wouldn’t recommend any products
