Wrong application guide!
Referred to Firestone guide and the 4186 kit is for AUTORIDE. does not work on standard coils. After I had installed them! Bag is way too short in a standard application for 2012 suburban 4wd

Schrader valves leaked at push tube fitting
Had to order additional schrader valves with 1/4” push tube fittings. Leaked slowly 4 days one would drop 20 psi and the other 5psi.

Went Bad Already
Bought in May (4 months ago). Run 10lbs of air in them. Worked great until.... Started leaking over a month ago. Finally had a chance to figure what the leak was. The leak was on the top of the bag where airline attaches. I removed the bag and attached a freshly clean cut line to it to confirm. Wouldn't buy this brand again.

Seems like a great product so far I used them in my 2013 Chev Tahoe, I found it easier to pull the coil springs right out and install the bags that way rather than try and stuff them up in while the coils are in the vehicle like instructions say to do. Didn’t change the normal ride much at all with 5 psi min. but worked good while pulling my camper with 12psi.
