as for bump stops get a rubber freeze plug ( the temp kind that have a nut you tighen) then take the bolt out of your upper plate and use the freeze plug as a bump stop/plate bolt..I saw a pic of a guy running it and it worked well
as for me I have no bump stops and cupped LCA so my LCA lays flat against the X member..my X is about 1.5" off the ground with stock spindles

I suggest you build a stop. Even the best engineered system "can" fail. If your system fails and you can't roll at all, you are at the mercy of being stuck where ever you are. That's not always a good thing.

I had an exhaust system failure the in turn melted an air line. I pulled over immediately. I got out and surveyed the landscape to discover I had broke down in the middle of nowhere. To compound matters I had almost zero cell phone reception. Wow, how lucky can one guy get to break down between two towns right in the middle of a dead cell zone.

Fortunately my system allowed me to roll sitting on the bumpstops. I rolled down the shoulder for almost 5 miles to a rest stop. I was able to pull safely off of the Interstate and wait for a rollback.

Bumpstops are a good thing.

[scotts62]

Yeah i am going to make some stops on mine too just for the same reason N2TRUX said about being able to get the thing off the road if something stupid happens.

N2TRUX- yeah that makes for a bad day and to boot with no cell phone reception been there before..

if you have an air failure and it drags you have scrub line issues not air......I would have jacked it up put a piece of wood in there and drove it home..but thats me....
with cupped LCA and a c notch I just clear the ground with my long headers the x member is 1" off

Sounds like a logical solution. That would not apply in my case for several reasons.

First off, I don't have scrub line concerns. In most cases when the system doesn't have a bump stop your tires are going to make contact with the fender liners, assuming you still have them.

Next problem is you are assuming this involved only one corner. In this scenario, I blew the supply line going to the valve block so I lost all four corners.

And last but not least, I carry extra line and fittings but this was in an area that was not readily accessible. I did have a small jack, but I did not trust it to lay under my truck while fighting a hot exhaust trying to patch the line up.

[Hottrucks]

if it was a supply line and it got broken and the bags where aired up it shouldn't matter..reason # 2 to keep your vavles close to your bags reason #1 would be the amount of air to charge a long line in more than a short one.....longer hoses off your tank means more storage...back in the day we would run fuel lines in a zig zag just to carry an extra gallon of fuel..sometimes thats the dif between winning and runing out

most solenoid-style spool valves do NOT work without back pressure ... regardless of where they are mounted

[N2TRUX]

Kinda hard to keep your valves near your bags when your running a manifold.

You can make up all the scenarios that you wish. The bottom line is a properly designed system should be able to roll if the system fails.

I think it all depends on what kind of truck ur building. daily driver - like n2trux said, u gotta have something there. u have more of a chance of something going wrong if u drive it everyday. on a project or weekend driver, most people probably wouldn't put one in because it looks all cluttered up in there. just my .02 cents on a bumpstump

my truck had a leak on the top bunge in the air tank that would leak out all te air yet I could still get in it and the bags where full...alot of time I would fill the bags before I parked it then dump them back into the tank before I let that would refill the tank a bit so the comp didn't have to work so hard

I agree there are alot of factors to consider when building I never gave a manifold a thought all my bags have there own lines

[chevydog66]

Cut mine completely off also.

[dznucks]

Mine will be a daily driver so I will need to fab a bumb stop.

Those of you running lower bag cups in the front, how tall are your's or howm uch did you cut them? mine are from SD and i would like to take off at least an inch.

[kev2809]

I believe I read for the 67-72 1.75" tall is the lowest, for the 73-87 1.25" tall is the lowest. I was gonna cut mine down but decided I want to get 8.5" cups and recess them into the lca to get a few more inches of drop

[dznucks]

kev, you mean 1.75" over all height of the cup?

Hey Michael Bustamante, I dont see a sway bar on yours?

DZL1.

when I took the pic I had taken the sway bar of to shorten the ends just like how you said. the bag just touched the sway bar as is. Modify modify modify

This is a simple way to do it. Looks natural and not cluttered.
I had my bumpstop setup this way originally before I went all out on my frontend.

that one looks good, if i run one it will probably be something like that. what bumpstop did you use?

yes, overall height of cup. i think the sd cups come like 3" tall if im not mistaken

[camaro__thunder]

You can purchase them at Oreilly or Autozone made by Energy Suspension.

[kev2809]

ok cool, thanks

[michael bustamante]

looks like Im doing another parts run to o reilleys!!! thanks for the tip on those bumpstops

[dznucks]

thats what i got for the front and backs. i ended up cutting a step off the backs.

I know this is an old thread, but it doesn't look like there's any way that bumpstop would ever actually hit. Correct me if I'm wrong!

[michael bustamante]

My first old thread to be resurrected!! at full deflation, these stop would actually hit the
LCA. this is an oldie though. I sold this truck in 2011! it was a fun ride but i found a 67 short stepper that needed refreshing.

The D2600 are 2.8" deflated and you have a plate on top, so there must have been at least 2.8" between the crossmember and LCA fully aired out, right?
