52-7371 Hydraulic Power Brake Booster For Chevy Avalanche Silverado 03-06 | Compatible with Chevy Sierra 1500 2500 3500 2003-2006 GMC Sierra 1500 2500 3500 Yukon XL 2500 2003-2007 Replace 15167550

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.

It seems to be working out just fine thank you for the part for my 3003 Chevy Silverado 1500 HD.

Good price and good quality for an upgrade. Had no problem installing and recommend if you are having leaks or weakness in your brakes.

Fit perfectly, been functioning great for a few months now.

Worked great on my 2005 2500hd. No leaks.

Junk, do not buy , item is made in china and sit 35 degrees left side slant . Holes dont line upat all. Seals leak bad .

No problem during the change out no leaks ,good fit

Good price for the item my biggest complaint was the fact it didn’t come with the pushrod, spring, and retainer. Had to reuse them from the old booster and I’m not a fan of that.
