Bump Stop Removal

dave_benn · June 20, 2011

I bought the Firestone ride-rite airbags for my 2010 Sierra, and the directions say to remove the bump stops. I went under the truck to remove them and to my surprise the head of the bolt is inside the bump stop, and the nut is part of the frame. Has anyone got a clue as to what size it is to get the bolt out. I tried a 9/16, 1/2 and the 5/8 is so tight getting in that im afraid if it comes off the socket i wont get it out. Thanks in advance.

You are correct, I don't know why i didn't try that before. By the way anyone looking for airbags, firestone ride-rite are a straight forward install. Ill let you know how they ride tomorrow.

good deal, I was considering a set of those. here's a hint: everything on your truck is metric except inside parts of the rear axle

The Firestone airbags are great. I didn't notice any difference in the ride. The truck tows great and my boat (24' & around 5000 lbs) doesn't squat the rear end at all now. I run the bags at 3-4 psi all the time.

I first filled up the bags to 30 psi, raised the truck about 3 inches. They fill fast, but i dropped them down to 20 psi and that was way to much for driving around with. The back end was way to bouncy. I let the air down to 10 psi and ill see how that does today. I think running them at 3-4 psi is too little. The factory says no less than 5 psi, don't know if that would ruin yours or not.

Where do people run the air lines for this set up? Out the back? Did you drill a hole for the lines? I am getting ready to install and was looking for tips or advice.

Thanks

what does the instructions say ????

you have to add a bracket or drill holes in the bumper to access the air valves ,its not to complicated ,dont worry to much about it

I used the lower license plate bolt holes.

Thanks. I will have to take a look at the lower license plate bolt holes. that sounds like a good place.

I wouldn't be drilling any holes in the tinfoil bumper pieces to insert the air

fill valves. I can see the tinfoil peeling off or worse! At $210 bucks a side

to boot for the bumper sides....................

I would fab up a piece of metal stock, drill holes for the air fill valves,

and mount under the rear bumper or where you could have easy access.

I drilled in on either side of the lisence plate. Its plastic.

will just add... try to get a 2 to 1 connector so you dont have to fill both bags one at a time and try to get the psi the same. A 2 to 1 will have the bags perfectly equal and no messing around with back and forth with the air hose and pressure gauge.

My cousin did his this way, except he used the top holes and used it to mount the tag. Recently he upgraded and got the compressor upgrade. That is a really nice setup, he can air up/down without having to get out of the driver seat. It will also air each side up independently so no matter how the truck is sitting or is loaded it balances out the load. The compressor fit perfectly on what looks like a tray for a second battery.
