Is anyone running air bumpstops with their 52" front springs? I have been running my rig in the woods for a while now with no bumpstops and its starting from holding me back from hitting some of the harder obsticals with speed. I am only running about 4-5" of uptravel and Bilstein 5125s.

I've got a couple sets of 4" bumps. I'm thinking about limiting them to 2-3" and mouting them to the frame so they hit the spring pads. Has anyone done this and have some pics???
 
I don't see why it would be any different with 52s than anything else. But if you have the down travel to spare, I would work on the upper mounts to get more uptravel. I'm in that same spot with only ~5.5" uptravel and ~9" down. That way you can set the bumps to bottom out and still have ~1" of uptravel.

I run stock length front springs, so maybe I just don't need that amount of down travel. I would like an extra inch and set my Timbren stops just short of that.

52" springs use every bit of a 14" shock if you let them. My rig is setup for rocks and anymore uptravel will negative arch the spring.

Agreed. I have 14" travel shocks on the front of mine, and it uses every bit of it. I used ORD's competition bumps (4.5 inch ones) and just bolted them in the stock location. They seem to be just about perfect to when it hits, the spring is pretty much flat (maybe just a tiny bit negative). I was thinking about making a small bracket to get them a little bit lower, but for now they seem to work really good.

Are you doing more high speed stuff? I could see a lot of benefit to those air bumps if you did a lot of sand runs (like Dueling) or something like that, but for just normal backwoods wheeling (not rock bouncing) I think a good poly bump would do just fine
 
My timbriens work very well. Way better than those 4" poly wedges!

I like the air bumps, they work. But I wish I hadn't gotten 4" travel ones. Id rather have 3" or 2.5" because its annoying having them hit so soon (I know you can take them apart and limit them, but I don't feel like doing that because they do work). They are quite clunky sounding when they hit. Idk if that would bother anyone else, but it annoys the crap out of me when im just slow cruising in the dunes and all I hear is them hitting.
 
I have 2" air bumps with 56s up front. I have about 3" of uptravel at the bumps. So 3" static up travel.

I love em, made a big difference. I still have some tuning to do with them but just messing around with the nitrogen made a difference.

Its not a revolutionary mod for sure but sure makes the hard hits a bit more bearable.

Like dueling said they are loud
 
I don't notice a sound out of mine. But by the time they hit, I am usually hanging on for dear life at that time.
 
Nevermind about my up travel comment lol. I reverse arch all the time. Meh, life goes on :D
 
I live in the southeast. Half the rigs I ride with are bouncers. A lot of the stuff we ride takes some wheel speed.

I was a bit worried about them being noisy but I wanna hit some of this stuff a little harder without breaking the truck in half.

Do yalls that says their noisy have metal pads? Mine have a plastic pad on the bottom. Maybe I set them up for the last 3" of travel and then if they hit too early, limit them to the last 2" of travel.
 
I like my timbrens. Only a couple inches of uptravel before they make contact but I don't really notice them unless its a really hard hit.

All of them I have seen come with delron pads on them. (a plastic). And yes that's what mine are. If your slamming on your rig all day, you wont really notice. Im just saying on my blazer and the soft ORD springs with 4" bumps, I can hear the bump stops hit at every pothole in the road...


If its hard hits all the time, I wouldn't be worried. When im on it in the dunes, I don't even notice them. Its more the cruising around that gets annoying with them hitting every other second...
