That always just struck me as way too hokey, and should one of those sticks split apart from a stiff bump, the resulting dragging around of your buggy's undercarriage with no suspension whatsoever would certainly not be a good idea.
I was wondering that there HAD to be a better way to rig up temporary shock stiffeners without having to completely rebuild the shocks, or use ghetto solutions like popsicle sticks, and I came up with this idea. It hasn't been tested yet, as I don't have my car running, but what do you guys think?
I bought a foot of rubber braided heater hose. Measured the approximate amount of space between the bottom of the shock body and the spring cup. Cut off a piece of heater hose maybe 3/16" shorter than this space. Slit it down one side. Removed spring cup & spring, slid the rubber piece onto the shaft, replaced the spring and spring cup.
Instant on-road suspension with limited travel, and from what I would imagine, no danger of major damage, as the rubber piece has a bit of give. The even better part is it only takes about 10 minutes to remove 4 shocks, remove the spring cups/springs and slip on the rubber "on-road sleeves" and replace the springs/cups & mount the shocks.

What are some of your other ideas?
