Hi zip thanks for the info ! It looks like the front and back shocks are similarly constructed. I'm going to remove my rears and replace the upper rubber mounts and trim the ure bumper . The rears do have more travel before hitting the bumper (fronts only travel one inch plus before hitting the bumper. I plan to reuse the front bumpers on one of my bucket loaders. I'll try and get a pic loaded of the front shock exposed later today. Thanks
