Great part for the money!!
I bought this item for my 96 c2500 silverado and the difference was like night and day after installing. I did read that some people got a bad part but, thats honestly that's a chance we all take when ordering something online. My device worked great, no issues, and I highly recommend it.

Dangerous aftermarket junk.
Absolute junk booster. Fitment was fine, but literally blew apart immediately after installing. Didn’t even make it down my driveway and nearly crashed in to a tree. Had to buy a Cardone to get the job done. I contacted the seller, and despite having just installed, they wouldn’t cover this. Granted, I had it for just over a year, but a lot of us guys with OBS trucks don’t drive them daily. We work on them piece by piece. In my opinion, with a background in automotive, this is NOT safe to buy. Pictures attached, small bits of metal came out when I turned it over so I’m sure the insides are absolutely wrecked. Placed in the trash where it belongs.

Faulty bad part. Supposed to be new.
Part came quickly, but box was really beat up and shaft hanging out because it was improperly packed. NO packing just rolling around in box. Then after part was installed it was faulty. Some kind of second?

Great direct replacement
Look, when your brake booster fails it dangerous and frightening at the same time. You step on the pedal and it’s hard and won’t depress and you need to stop now but what took 50 feet to stop before now takes 100 feet. You need a new brake booster, stat! This booster is a direct replacement and works perfectly. Sure it’s a little tough to contort your body under the dash to remove the 4 nuts and rod/brake pedal clip , but it can be done. Good luck and save a lot of money with purchasing this brake booster and installing this yourself. I recommend this part and vendor. Only issue I had was the shipping box. It was inferior and not packed safely for transit.
