Good afternoon, Mud sirs!

I am about to install Airlift bags in my 97 LX450 with 197K on the clock. This has OME 862 rear springs that are in good condition. They were part of a kit ordered from Slee a couple years ago. I wish, like hell, I had installed a lifted and heavier spring / kit when doing this but I had no idea where my truck was headed. The budget has dried up for a while and I'm stuck making the best of what I already have.

My questions is, whether tis nobler in the mind's eye to cut the rear bump stops or to remove them entirely. I've read conflicting info on the matter and am hoping that some one can chime in with a definitive answer. I have an event in a couple weeks, #GSMTR, and need this to carry the gear.

I have the airbags installed on mine, and I removed the rear bump stops completely (I have heavy OME springs). I really didn't/don't notice any difference. The only reason I bought them was because I use to have a rooftop tent.

PS. We should link up at GSMTR. I'm coming on the 14th.

I trimmed the rear bump stop of a few segments when putting these on my '97. They've worked well for the years I've run them but have recently started to lose pressure so I'll soon get to find out where the weak point in my install was.

Hit me up! I’ll be there on Friday.

What kind of springs are you running?

Stock springs with Dobinson spring spacers for now. Sitting around 21" wheel center to flare bottom on all 4 corners, though the rear varies based on air pressure/load. Have been contemplating aftermarket springs but probably won't make that shift until new tires.

I don't have pictures of my air bag setup but can get some when I do the leak check in the next week or so. I'm downtown/Northshore so pm me if you want to drop by one day to see my setup. It's not complicated to install the bags but if seeing them installed would help you are welcome to check mine out.

I added Airlift bags on my truck when I still had stock springs. I removed the bump stops completely.

I have since moved to 863 rear springs (2.5" lift, heavies) and I have installed the bags in those and they still work great.

I chose to keep my bags on a tee so they both fill at the same time and I have the Schrader valve in the gas fill inside the cover.

The air bags work by "binding" on the spring coils, not by pressuring to the top and bottom of the bump stop areas.

Never have them less than 5 LB and I never pump mine more than 25 PSI. I have blown one out through the coils at 35 PSI.

Exactly what I needed. Thank you!
