Limiting Straps and Bump Stops

Hi guys. First post here.

I just bought a little rock bouncer a couple of weeks ago. Sammy Bouncer. You have probably seen it on Hardline. Nice little rig.

In the winter down time (Midwest) I'm tweaking a few things before the season starts.

Along with getting the brake lines routed a little better and moving the battery to behind the seats for better weight distribution and easier access I feel like I should address the King Air Shocks.

I talked to King the other day and the rep informed me that my air shocks do not have any internal bump stops up or down and he said that if I do bottom or top them out it will be metal to metal, which will eventually tear them up.

To deal with droop I can pretty easily figure out some nylon limiting straps, but for compression it's a little harder.

There isn't much room in front and there are some rubber bump stops already installed, so even though I would like to have air bump stops F&R I might just let that end go for now.

I looked at the rear section of the tube frame today and can't really figure out a good way to mount bump stops for the rear axle.

Most all the rigs that I have looked at have air bump stops installed, but they are much heavier than mine.

Even though the King rep wasn't too keen on the idea there is the fact that air (nitrogen) shocks ramp up under compression because the gas is being squeezed more an more and the axle goes up. So maybe I don't need to worry about it and just install the limiting straps.

I guess I could wait to go ride and see if I bottom it out. The builder and previous owner said they never had any problem with it.

Here are a couple of shots of the rear of the buggy.

What are your thoughts.

Thanks.

Looks like you will have to add some tube work on the rear if you plan to add some bumps. Neat looking buggy.

Thanks Dan. The question was more about do I need to bother with bump stops and limiting straps.

I may be wrong but can't you add oil to keep air shocks from bottoming? If I'm right you could just add enough oil so the shock with no air would hold the shaft out 1-2"?

What/who added to the rear of the cage it didn't used to stick up like that

If you over fill the shock with shock oil it will hydraulic, just like a motor will.

That was the second owner. He said he had to hold his head sideways so he didn't hit. It is actually a good height for me too. Just wish he had hired a better welder. I think he also moved the clutch brake mounting point forward. I can just barley push the clutch in all the way on my tip toe. I need to address that. I need to move it back 4 to 5 inches and also move the throttle pedal forward a few inches. I think I'll mount the c/b on a plate with adjustment holes. Not much I can do about the cage unless I cut it all off and re do it. Not too bad from the outside but kind of an eye sore while you are sitting in it. I wouldn't mind if the rest of it looked the same but it was a pretty clean build and I only want to make it even better.

Simple solution to clutch pedal:

you are a genius patooyee! So much easier. I could even put a couple of sheet rock screws in the board to help hold the zip ties. I'm on it.

I never added any oil. So there in stock form. May could call king and they could tell you how many cc's to add. It weighs around 2000lbs

I HAD NO PART IN THIS!
But will say it was the most fun lil rig ive ever owned.

I imagine the oil in there is fine considering how little rock time the buggy has gotten. Although I guess the fronts were used when it was a Samurai for a while first. I ordered a King metering tool so once I get a nitrogen bottle and regulator I can adjust the spring rate. This is kind of key to air shocks as they are effected quite a bit by temperature changes. Sitting pretty low in my cold shop. The King guy said to go for about 25 to 30% sag. But that seems really high for bouncing. I'll have to experiment.

Maybe some day, if I don't buy a bender and do it myself I'll get the rig down to you again so you can rebuild my roof.

So what was that tubing again? I haven't measured it. 1.75" .120 hrew"?

What bender do you use?

1.75 120 hrew I use pro tools 105hd.

I'm not as much concerned with the way the extension looks. It's not that bad. I'm more concerned with the strenghth. Big drop on the top. ???
