I saw this on a Monster truck last weekend. I was totally impressed. This guy made adjustable bypass shocks out of hyd. cylinders. I think the small cylinder is an oil reservoir.





Here is the pricey version.

Interesting concept. I would venture to say that that set up is much better for the power and weight they are supporting. I wonder if thats more of a standard on Monster trucks that a normal shock setup.

I don't know Ody, I see no other visable signs of support. The link behind the shock, I'm guessing without seeing the other side, is a sway bar. If it were a torsion bar it would have a bunch of twist for the wheel travel. Don't know.

I am just talking about the Cylinders being being better than normal shocks. I really had not examined the whole suspension.

I have heard stories of guys racing back in the day when you couldn't buy bypasses (or wouldn't cuz of cost) that made their own out of normal rebuildable shocks. They would drill holes (bigger or smaller depending on how much "bypass" they wanted) in the shock body at one end, then figure out where they wanted the valving to work again and drill another hole in the body. Then they would weld a big piece of tubing (1/4" inch or so larger id than the od of the shock) over they body, and you would have a "bypass". I imagine that they wasted a few shocks getting it to work right, but I love hearing stories like that!

That is seriously one of the ugliest shocks I've ever seen. Nevertheless... I bet he's having fun!

The small "cylinder" is an air charged bladder style accumulator. By adjusting the pressure in the accumulator he can adjust his "spring rate". I have done similar style setups for hydraulic ride control on other vehicles. I work as a hydraulics engineer, and we see this in a much less crude version quite often. Several military vehicles have used this concept. I have only seen it on very heavy vehicles, but no reason you couldn't size it for a buggy.
