Saved a few bucks
Was slightly different from the OEM assembly on my 2012 F150. Worked normally. Check valve seemed a little less substantial.

ORM Fit and Quality
Oem quality! These were super easy to install, and fit perfectly. Fixed the issue I was having with my 4WD. It got rid of the grinding noise from my 4WD staying engaged.

Vacuum line
Vacuum line itself is good super fast shipping g reasonable price only problem is value keeps coming apart most of time Dorman is good value on line is junk might have to put old value on did not fix grinding but did not think it would but I broke line on my truck so I still needed it

Quality part
Had a rough grinding coming from the front differential on my Raptor and this was the fix. Easy plug and play.

Poorly made
Went to pull the hose connection off and the valve split in half. Very poor quality. Spend the extra money and get the OEM since it’s not much more.

Check the valve position
Mine was assembled with the valve upside down! Needless to say, it didn't function properly that way!
