Have an esoteric question...Is there a way (other than jack up the vehicle and pull out the measuring tape) to calculate the maximum articulation of a spring set-up? I'm considering doing some suspension mods, and will need to get new shocks, and want to try and determine how much articulation will take place so I don't get the wrong shock set-up.

The basic idea is to add a shackle between the frame and the existing shackle, that bolts down for highway use, and can be freed for four wheeling. (It's similar to the tera-flex set-up, but won't pivot). I'd move the shakle hanger forward about 7.5 inches so when compressed, the stock shackle is in the right place.

I'm thinking that if I can calculate the max articulation of the leaf spring, I can add the extension of the second shackle, and get a close estimate of how much the shock needs to be able to move.

any thoughts or ideas would be greatly appreciated.

Thanks
