Don't know if it is a language problem (I'm frome Sweden) but I don't understand what droop on the suspension means?

Can some one clarify it for me, please.

what is a droop suspention?

try this and see if it explains.

Tank you! That made it all clear. Exept for why

it makes so that you have a lower center of gravity but if you hang up on your chassis your axles will still drop down and hopefully catch traction and pull yourself out.

I suppouse this is manly for the kind of chassie that is built for it. Nothing to do on a standard AX10 chassie. At least not full droop?

You can run droop with the stock chassis, just make sure to use a bit of fuel tube to limit how far the shock compresses. A stock ax10 with a 50/50 droop set (spring under and above the piston inside the shock ) works very well.

Interesting. Think maybe I will try it. But will it not be bad ground clerance?

Most of your weight is on the axles.
When driving/crawling around, your hold-up springs(as in regular sprung or the springs over the piston in a semi-droop) are strong enough to hold the chassis up.
When the chassis gets hung up, the weight of the axles overpowers the droop springs (in a droop setup or the under-the-piston ones in semi-droop), the axles drop, gain traction, drive the chassis out of the bind. You NEED a slippery skid if you're making a belly dragger.

The reasoning behind using reverse springs in droop and semi droop is chassis weight transfer control. When sidehilling/going up inclines, the chassis will tend to fall over sideways or backwards. The springs, being strong enough to hold the weight of the chassis but not strong enough to support the axles, keep that in check.

These are 2 pictures of my WK in the first stages of being converted to droop. The shocks in these pics did NOT have droop springs. See how the chassis pulls back on the vertical and leans to the right on the other picture. I had very heavy oil in the shocks, had I taken more time to take the second picture, the lean would be more obvious.
