I just checked mine and they are stamped. Get underneath the jeep and wipe off the lower portion of the shock. My fronts are stamped N66 underneath the word MAN. As far as the springs I would look for any remnants of a tag attached to them. If there aren't any tags you could contact ARB directly they may have a way to identify them by what they look like. As crazy as this sounds you could also pull up on the next wrangler you see. Get out and verify it's stock and then whip out a tape measure, then you'll know for sure how much lift you actually have.

OME ZJ/LJ lift, 33" MT MTZ on AR-23 wheels, front and rear JKS trackbars, 1" seat risers, MORE 1" BL and MML, factory Ipod adapter. Light khaki jeep club #72
