Instant fix!
My truck was starting to have the hubs grinding. This instantly fixed the issue and potentially saved hundreds of dollars down the road.

Failed in 6 months
The check valve split in two within 6 months of installing.tried to superglue it together but it no longer holds vacuum pressure.

Easy to install!

Slightly cheaper then OEM, but just as good
Easy to swap. No getting dirty as it’s under the hood. Seems like decent quality. It has lasted for 250 miles and I expect 70k more. Solved my front intermittent wheel grinding-like sound.

Great replacement
Replaced when original gave out. I do not think it is as high quality as OEM but is doing the job.

Complete Junk
Showed up with sketchy packaging and no label. Did not work at all. Had occasional hub grinding which became constant when I installed this piece of junk. Put the old one back on until I could pick up the OEM. Do not buy

Go with OEM!
Ordered this for my truck. Took truck to dealer, and they replaced it with a Ford one. Truck is fixed. Go with OEM! It’s just a few dollars more!

Kinda cheap
Not sure if I just got a bad one. But the check valve itself just broke..plus it does come from China. Bought it for my 2017 f150.
