Over the years we have had a problem with some vehicles, where the Lift Frame would have to come down too far to rest on the top of the Crankstand. On some EZ Plus mounts (mostly Ford Superduty) when the Lift Frame was sitting on the top of the Crankstand, the mounting pins when unlocked, would shoot out UNDER the Clevis. We overcame this by cutting a block of 1.5" thick Urethane Cutting Edge scrap. Now with the new Drive Pro SOS, we have a different problem. When removing the plow, when oyu pull the handle to disengage the mounting pins, the Lift frame hangs in mid-air. It is a geometry problem. When you back the vehicle away, the Lift Frame slams down onto the top of the Crankstand, and it makes the back of the Lift Frame too high for the next time you go to mount the plow. Installing this snubber can solve your problem. VERY easy to install, you will need to drill a 1/4" hole to install it. You remove two nuts and carraige bolts holding the top of the Crankstand on, drill your 1/4" hole, install snubber with hardware provided, then reinstall the two bolts and nuts. It is a 5 minute job, if that.
