Thanks Hank! Nice pictures and description. This looks like it may be one of the next upgrades on my list.
After reading some other posts of Keystone owners having shackles to fail, while installing these I likley will beef up the mounting brackets to frame. Looking down frame on my entry side, my shackles have a appearance of leaning toward the center of trailer. Will get a straight edge and rule and see if it is just a perception.
